摘要
作业场所空气中铅的测定,除了采样外,酸消化过程也是非常重要的步骤。深入分析酸对铅测量结果的影响,结果表明酸含量对测量结果影响不大,但消化液、高氯酸与硝酸在对测量结果的具体影响上不尽相同,略有差异,总体上都是随着酸含量的增加,测量结果逐渐略微偏低,因此实际的工作中应当尽量把酸蒸发完全。
Besides sampling, acid digestion is another important factor during the the workplace. Acid effect on lead measurement was analyzed completely. The results process of measurement of lead in showed there was no much effect, specifically lead containment decreases in a small degree with the increase of acid volume, but for digestion liquid, perchloric acid and nitric acid, slight difference existed between them. Therefore, acid distillation should be done completely in the daily work.
