的三个温度下测定了珠江口20个水

样的密度。结果表明,测定值皆高于相应条件下国际标准海水状态方程的计算值,在海水盐

计算密度的偏差随盐度的降低而增大,与盐度的变化成直线相关:与(Ca2+)/S、SO

42-/S比和比碱度之间皆呈指数曲线相关。珠江口水样(Ca2+)/C1、SO4

2-/C1和比碱度平均值分别超出大洋水平均值17.8%、8.21%和152%,其余的Na+/C1、

K+/C1和Sr2+/C1比值与大洋水无明显差别,基本类同。珠江口海水的高碱度、高

(Ca2+)/C1和高SO42-/C1是造成其海水密度正偏差的主要因素。经计算机拟

合,首次导出了珠江口海水密度的状态方程,该方程计算值与实验值的平均标准偏差为±2.

Abstract The density and salinity of 20 seawater samples co

llected from the Zh

ujiang Estuary were measured with a high precision magnetic float densimeter at

15.536℃,19.602℃ and 24.976℃, respectively. The major ion content of calci

um, magnesium, strontium SO42-, alkalinity, pH, chlorinity and salinity

etc. were also determined. All the measured densities were higher than those cal

cul

ated by the international Equation of State of Seawater, 1980. The average diffe

rence between the measured and computed densities increase with the decrease of

salinity. The arerage difference of density varies from 2.4 to 54.0×10-3k

g/m3 in salinity ranging from 0.08 to 33.446.The relationship between the aver

age difference and the ratio of Ca

2+/S,SO42-/Cl or specific alkalinity appeared to be exponential with

salinity. The mean Ca2+/Cl ratio, SO42-/Cl ratio and specific alk

alinity were 17.8%,8.21% and 152% higher than their corresponding average values

in ocean seawater. The Na+/Cl ratio, K+/Cl ratio and Sr2+/Cl ratio

were similar to those in the ocean. It was the high Ca2+/Cl ratio, SO

42-/Cl ratio and specific alkalinity that resulted in the higher measured

densities of seawater than the calculated densities in the Zhujiang Estuary. The

resulting densities of all samples were then fitted to the following equation o

f density (×10-3kg/m3):d=a+bS0.5+cS2, where S is salinity, a, b

, c and e are temperature—dependent parameters. The

average standard deviation between the calculated densities from this equation a

nd the experimental values is 2.5×10-3kg/m3. The density difference can

also be estimated from the equation d(10-3kg/m3)=a'+b'[Ca×10-3

]0.5+c'[Ca×10-3]+e'[Ca×10-3]2,where a',b',c' and e' a

re temperature—dependent parameters, with an average standard deviation of 1.4

×10-3kg/m3.

9.60℃ and 24.976℃, respectively. The major ion content of calcium, magne

The average difference of density varies from 28.2 to 120.5×10-3kg/m3

The relationship between the average difference and ratio of (Ca2+)/S or

. The specific alkalinity exceeds that of the average value of ocean seawater 60

Investigation on Boron in the Seawater of Jiaozhou Bay

(Ocean University of Qingdao, Qingdao, 266003)

Abstract Dissolved Boron in the seawater of Jiaozhou Bay is

studied for the first time. Boron content has been determined with sensitized r

eaction of emulsorthe OP micelle curcumin method newly developed by us. The an

alysis of the samples collected during October, 1989 and May, 1995 shows that th

e Boron in the seawater of Jiaozhou Bay varies from 3.24 mgkg-1 to 3.87ngkg-1, t

he average ratios B(mgkg-1)/CI and B(mgkg-1)/S are 0.204±0.009×10-3 and 0.113

±0.005×10-3, respectively, lower than those in ocean waters. The ratios B (mgk

g-1)/CI and B(mgkg-1)/S vary from 0.181 to 0.215 and 0.100 to 0.120 separately.

The concentration distribution of Boron in the seawater of Jiaozhou Bay shows th

at the low value regions are nearby Li Cun river mouth and Cang Kou Bay, but the

high value regions are in the northeastern part, Jiaozhou Bay mouth and both si

des of the Bay. The dissolved Boron in the seawater of Jiaozhou Bay is mainly de

rived from the external seawater and the high salinity brines. Without the river

s flowing into the sea throughout the year, the salinity distribution in seawate

r of Jiaozhou Bay varies vary small. In proportion to Boron in the Yellow Sea, t

he average percentage removal of Boron in the seawater of Jiaozhou Bay is 8.65%.

The percentage removal of Boron was calculated using the concept of the theoret

Abstract The determination of Boron in the medium of nonionic surfactant soluti

on(water content 85%) was investigated for the first time. The optimum experimen

tal conditions were determined through experiments. The classic curcumin method

of Boron determination was improved. Boron in seawater can be determined by thi

s micellar enhanced spectrophotometric method to avoid the interference of salin

ity. Experimental results showed that the sensitivity of determination was enhan

ced greatly(E=1.5×105), the linear range was broadened(0~1.2μg/25mL), and th

e colored complex compounds remained stable for up to 50 hours.

Abstract Three fractions of<1.0μm,<0.4μm and <5000Dalton

truly dissolved fraction was relatively stronger than that in larger size fract

in larger size fraction was relatively stronger for the Changjiang freshwater s

lton(corresponding to 1.5nm) by filtration and crossflow ultrafiltration. The dy

eared fast, however, those in <0.4μm and <1.0μm filtrates appeared slowly.

For t

filtrates and ultrafiltrates were slow. The complexation of lead in the Changj

nd <0.4μm and <1.0μm filtrates of the Huanghe River samples were determined by

the reaction between lead and colloid. The rate was controlled by liquid film d

t letwards and the isotherms shift upwards as ionic strength or salinity of the

media is NaC1O4>NaC1>seawater, which indicates that there is a complexation ef

Abstract Based on the samples collected in May 1996, this

study summarizes the levels and distributions of dissolved trace amount of alumi

num in the Yalujiang Estuary. The concentration range of dissolved aluminum in t

concentration and distribution of aluminum in the estuary,the flocculation of d

Higher temperatures favor the formation of higher alcohols, especially ethanol.

Abstract We incubated Zooxanthella microadriz tica at 1

8±1℃, and determined the change of DOC in the solution during its culture usin

g the UV/persulphate oxidation method. The results suggested that there was a li

near relationship between DOC and the weight of Zooxanthella microadriz tica

during the index stage of

its bloom. The experiment of the limitation of nutrient indicated that the incr

ease of weight of Zooxanthella microadriz tica was very slow and DOC increas

ed

negatively when there was no phosphate added. The more the phosphate was added,

the more rapidly Zooxanthella microadriz tica increased. And the accumulati

on a

nd releasing velocity of DOC was more rapid also. When the concentration of phos

phate was 10μmol/L,the proportion of DOC released from Zooxanthella microadr

iz tica cells to the whole compounded carbon of photosynthesis was the highest

摘 要 利用差热分析(DTA)和程序升温还原(TPR)技术

研究了活性炭担载钼基催化剂在制备

和预处理过程中的性质变化。DTA结果表明,催化剂在焙烧过程中产生了新相,这种新相与

活性组分和载体间的相互作用有关,助剂K和Ni的引入对这种相互作用有明显的影响。K/C样

品的TPR结果表明,K本身不被还原,但它可以改变催化剂中其它物种的还原行为。C担载Mo

基催化剂的TPR谱一般由四个正峰和一个负峰组成,正峰归属为不同Mo物种和载体本身(包括

其中的某些杂质)的还原,负峰则归属于氧化的C载体表面脱附出的CO,Mo担载到活性炭上后

变得更加难还原了。K的引入大大促进了低温下可还原Mo物种(主要是八面体Mo)的形成,而

抑制了那些仅在高温下才能被还原的Mo物种(主要是四面体Mo)的产生。这可能是影响催化剂

在CO加氢反应中的选择性的一个重要因素。

Abstract Differential Thermal Analysis (DTA) and Temperatur

e Programmed Reduct

ion (TPR) techniques have been employed to study the property change of the carb

onsupported molybdenumbased catalysts during the preparation and pretreatmen

t process. It is shown from the DTA results that a new phase, which is related t

o the interaction between the active component and the support, may be formed du

ring the calcination of the Csupported Mo catalyst. The introduction of the K

and Ni promoters has noticeable effects on the interaction. The TPR results from

the K/C samples indicate that K is not itself reduced, but it may modify the re

d

uction behavior of other metal compounds. The TPR spectra of Csupported Moba

sed catalysts generally consist of four positive peaks and one negative peak. Th

e positive peaks are attributed to the reduction of different Mo species and the

support itself (including some of its impurities). The negative peak is contrib

uted to CO desorption from the surface of the oxidized carbon support. The Mo is

more difficult to be reduced after being supported onto the carbon support. The

introduction of K greatly promotes the formation of Mo species reducible at rel

atively low temperatures while it retards the generation of Mo species that are

reducible only at high temperatures. This may be an important reason that is res

ponsible for the selectivity of the catalysts in CO hydrogenation.
