摘要
工业废水通过工业排污渠道直接排入河流海洋给生态环境造成了恶劣的影响。本文论述的"双硫腙(H2DZ)-醋酸正丁酯萃取-HNO3反萃取前处理体系"方法可在保持检测样本所含成分的同时对铅元素进行有效分离,并通过试验操作证明了方法的实用性,所得结果为铅元素测定处理提供借鉴依据。
Industrial wastewater directly discharged into rivers and oceans through industrial sewage channels has caused adverse effects on the ecological environment.In this paper,the method of＂dithizone（H2DZ）-n-butyl acetate extraction-HN03 reverse extraction pretreatment system＂can effectively separate the lead element at the same time of keeping the samples containing the samples,and proved the practicability of the method through the test operation.The results provide reference for the determination and treatment of lead elements.
