摘要
对国标５７５０ － ８５ 双硫腙分光光度法中消化水样时铅的灰化损失进行了探讨， 针对某些污染严重的水样， 改进了消化处理的条件， 有效地消除了灰化损失， 提高了铅加标回收率， 保证了分析测试数据的精密度和准确度。
The ashing loss of Pb in water samples has been studied in digestive method for determination of lead by dithizone spectrophotometry(GB 5750-85).After the digestive conditions are improved,the digestive loss of Pb in some polluted water samples is prevented.The recovery of Pb rised ,the accuracy and precision of the analytical date are guaranteed.
