Influence of the concentration of Cr in the leachate and quantity of Pb(CH3COO)2 of Pb(NO3)2 on the reaction of synthesizing yellow chrome was also studied. Finally, according to the criterion and standard method in GB3184-82, some yellow chrome synthesized in the experiments was sampled and the concentration of PbCrO4 in these samples was determined. The following conclusion can be drawn from these experiments.

根据中华人民共和国国家标准GB3184-82中的规定铅铬黄颜料的技术质量指标和检测方法，测定了铬黄样品中铬酸铅含量的厂迄回【、矾士牢位论父泅仰yW盯皿'S川mS达标情况，结论如下：门）反应中重铬酸盐的浓度并不需要达到前人所提出的150～2509·L'的范围，在一定条件下低于此浓度时对铬黄生成反应并无不利影响。
