摘要
研究了在聚乙烯醇存在下,Pb(Ⅱ)—二甲酚橙—甲基紫三元络合物体系光度法测定痕量Pb(Ⅱ)的新方法.该法灵敏试高(ε=4.8×105L·mol-1·cm-1),选择性好,用于人发中铅的测定结果满意.
In this paper the spectrophotometric determination of trace with the ternary comples system of Pb(Ⅱ)-xylenol orange-methyl violet has been introduced.The method has good selectivity (ε=4.8×10~5 L·mol^(-1)·cm^(-1)) and precision.It has been used to determine trace lead in human,hair with satisfactory results.
