季胺盐萃取分离光度法测定水质中痕量铅的研究

DETERMENATION OF TRACE LEAD IN WATER BY EXTRACT SEPARATION PHOTOMETRIC METHOD WITH CAPRIQUAT

使用季胺盐萃取水中痕量铅,其它金属离子不被萃取,避免了使用毒性氰化钾。建立了水质中痕量铅定量分析的分光光度法。

Abstract Extraction of trace lead in water by use of capriquat. Other metal ions wouht not be extracted. the poisonous potassium cyanide would not be used. The spectrophoto-metrie method detected trace lead in water was established.
