用阳极溶出伏安法研究天然水中铅与有机物作用的特性(英文)

THE STUDY OF CHARACTERIZATION OF LEAD-ORGANIC MATTER INTERACTION BY ANODIC STRIPPING VOLTAMMETRY IN NATURAL WATER

将内蒙古的呼伦湖、中国南海北部的所有水样通过０．４５μｍ过滤，用阳极溶出伏安法进行测定．在天然ｐＨ下，测定了铅的表观络合容量和条件稳定常数．呼伦湖的络合容量（Ｃ．Ｃ）比海水大，ｌｏｇＫ相近，海水的Ｃ．Ｃ极大值在表层，随深度增加而减小．

All samples were filtered(0.45μm),and were determined by anodic stripping voltammetry in Hulun Like of Inner Mongolia,Northern water of South China Sea.Under natural pH,apparent complexation capacity( C.C ) of Pb,conditional stability constants(log K ) were determined.The C.C of Hulun Lake was greater than seawater ,log K were similar.The C.C of seawater is maximun at the surface layer,decreasing with depth.
