摘要
本文提出了一个以硝酸银-明胶-乙醇为氢化铅吸收显色液测定微量铅的新的分光光度法。该方法试剂毒性小、操作简便快速、灵敏度较高,氢化铅发生率达87％。用于分析沉积物样品,取得了较好的结果。
A new silver salt spectrophotometry is presented to determine microamount of lead, in which the generated lead hydride is absorbed by an absorbing solution of silver nitrategelatin-ethanol, The adventages of this method are low toxicity of reagents, simple and fast operation, high sensitivity, That the yield obtained for the lead hydride generation is 87%. Determination of lead in deposit samples shows better results.
