摘　　要：在氨 -氯化铵介质中 (pH =10 .5 ) ,镉 - 8-氨基喹啉配合物于 - 0 .86V处产生灵敏的吸附波 ,其二阶导数波高与镉的质量浓度在 0 .0 0 1～ 0 .2mg/L范围内呈良好的线性关系 ,检出下限为0 .0 0 0 6mg/L。该方法用于环境水样微量镉的测定 ,其结果与其它方法吻合。In the present of medium ammonia-ammonia chloride (pH=10.5),the complex of cadmium-8-aminoquinoline brings about sensitive adsorption wave at the point of -0.86V. Its 2 nd order derivative wave height is better linear with mass density of cadmium in the range of 0.001～0.2mg/L.The lower detection limit is 0.000 6mg/L.This method is used to determine trace cadmium in environmental water sample getting the same result obtained by orther determination methods.
