摘要
本文采用物理涂汞电极阳极溶出伏安法测定了中国南海北部海水中铅的表观络合容量为0.7~9×10^(-8)M。实验数据表明,南海北部海水中铅的络合容量比黄河口海水及青岛海水的络合容量稍大。铅可以和南海海水中的可溶性有机配位体形成稳定的螫合物。水柱的络合容量变化规律为表层最大,向下逐渐减小。此趋势同Romankevich 调查的世界三大洋溶解有机碳的垂直分布一致。
Determination of the apparent I ead complexation capacity by anodicstripping voltammetry with a physical—film mercury electrode,0.7~9×10^(-8)M.The data showed that the complexation capacity of South ChinaSeawater was greater than that in Huanghe Estuary and in Qingdao.Itwas found that Pb was really in non—labile camplexes with dissolvedarganic carbon.The complexation capacity profiles got maximum atsurface leyer and than decreased as the depth increased.It is similarto those got by Romankevich for the Pasific the Atlantic the Indian Ocean.
