标准摘要
[中文适用范围]: 本标准规定了测定橡胶中铅含量的原子吸收光谱法。 本方法适用于生胶和橡胶制品。 可测定的铅浓度没有限制。 只要对测试部分的质量和/或所用溶液的浓度进行适当的调整,就可以确定高浓度或低浓度。 使用标准添加方法可能会降低检测下限。 [外文原描述]: This document specifies an atomic absorption spectrometric method for the determination of the lead content of rubbers. The method is applicable to raw rubber and rubber products. There is no limit to the concentration of lead that can be determined. High or low concentrations can be determined, provided that suitable adjustments are made to the mass of the test portion and/or the concentration of the solutions used. The use of the standard-additions method might lower the bottom limit of detection.
