| 摘 要： | 为给渤海湾北部海域重金属铜环境容量研究提供科学依据，采用阳极溶出伏安法对该海域12个站位表层海水样品的表观铜络合容量(ACuCC)和条件稳定常数(K)以及络合容量指数(CCI)进行了测定和计钟：。得到该海区表层海水的表观铜络合容量在228．0～673．4nmol／L之间，平均值为437．5nmol／L，条件稳定常数对数值(IgK)变化范围在7．41～8．84之间，平均值为7．89，络合容量指数在72．69％～92、92％之间，平均值为82．93％。表明该海域表层海水对重金属铜具有较强的络合能力。

| Abstract: | Using anodic stripping voltammetry (ASV),the apparent copper complexation capacity (ACuCC), conditional stability constant (K) and the complexation capacity index (CCI) of 12 seawater samples collected in the North of Bohai Bay in 2003 were investigated and calculated. The ACuCC values in the area were between 228.0 and 673.4nmol/L, the mean value being 437.5nmol/L, the lgK values were between 7.41 and 8.84, with a mean of 7.89. The CCI values were between 72.69% and 92.92%, the mean being 82.93%. Which shows that there is a strong complexation ability for Copper in the North of Bohai Bay. |
