摘要
牙膏样品用HNO3-H2O2分解后,采用汞膜玻碳电极阳极溶出伏安法测定试样中的痕量铅。方法的回收率为96-106%,相对标准偏差为5.7%
Abstract: After being decomposed by HN03-H2O2, the dentifrice compositions were used to determine its trace lead by anodic stripping vol tammetry with mercury film glassy carbon e'ectrode. The recovery rate was 96-106%, the relative standard deviation was 5.7%.
