对硫酸钼锑溶液加抗坏血酸后溶液有时出现草绿色或兰色的现象进行了研究。查明：去离子水中的可溶性硅是主要影响因素；采用将钼酸铵直接溶于硫酸溶液中的改进方法是克服这一现象的有效措施；溶解钼酸铵的硫酸溶液酸度为３．３２～８．５５ｍｏｌ／Ｌ时，对所配试剂质量均无影响。
The phenomenon of grass green or blue sometimes appeared after solution of ascorbic acid and molybdenum sulfate antimony was studied. It is found that the soluble silicon in deionized water is the main influencing factor; the improved method of directly dissolving ammonium molybdate in sulfuric acid solution is an effective measure to overcome this phenomenon; the acidity of sulfuric acid solution dissolving ammonium molybdate is 3.32 ~ 8.55mol / L, the quality of reagents with no effect.
