摘　　要：根据古代青铜器铅提取液的性质及质谱仪对样品的要求,对国标中双硫腙分光光度法测铅进行改进,选用具塞试管代替分液漏斗,取消掩蔽剂,减少原溶液用量,结果表明该方法操作简便,校准曲线在较大铅浓度范围内线性较好,完全满足质谱测试前铅含量测定要求。According to the properties of lead purification solution and the lead-requirement of TIMS,the dithizone spectrophotometric method was improved,by using plug-tubes instead of separating funnels,canceling masking agents,reducing the original solution volume.The results show that the method is simple,convenient,which has a good linearity,and satisfied the lead-requirement of TIMS.
