摘要
海洋沉积物中间隙水的元素分析测定,我国研究得不多,特别对于间隙水的微量金属元素测定就更少。六十年代初期,有人用压取法分析测定了沿岸及海湾间隙水中的几种常量元素及营养盐,但收集的资料是零星的,且方法也不够完善。
The concentrations of Zn,Cu,Pb,Cd,Sn,and Bi ions in interstitial waters from the East China sea have been measured.The"antiadsorption physical coating mercury film electrode inverse polarography system"was used for the measurement.The"dilution methed"was used to obtain the interstitial water.The concentrations of the above ions in the interstitial waters are about 2-6 times higher than that in the sea water.The high ion contents are in the muds in which the Eh was negative and the pH was around 7.6.The low ion contents are in the sand.Obyviously,it was caused by decomposition of bio-organic matter in mud,and the low pH and negative Eh transfer the Zn,Cu,Pb,Cd,Sn and Bi into the interstitial water.
