摘要
采用火焰原子吸收分光光度法测定地表水中的铜、锌、铅、镉时,通过消解、浓缩水样后测定铜、锌,能提高测量准确度;用共沉淀法对水样金属离子进行共沉淀捕集后测定铅、镉,有效提高了灵敏度,扩大了仪器分析运用范围。
The accuracy of determining copper and zinc and lead and cadmium in surface could be improved through digestion and water sample concentrate. The sensitivity of testing lead and cadmium after trapping the metal irons using co - precipitation method was effectively promoted. These would expand the usage of the equipment.
