| 摘要: |
| 对硫酸钼锑溶液加抗坏血酸后，溶液有时出现草绿色或蓝色的现象进行研究表明：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在3.32～8.55mol L-1H2SO4时，对所配试剂质量均无影响。 |

| Abstract: |
| This paper studies the phenomena that when ascorbic acid is added to the
mixtural solution of sulphuric acid,ammonium molybdate and potassium antimony tartrate,grass green color or blue color occurs in the solution.It has been detected that the
soluble silica in the deionist water is the main influencing factor.Directly adding ammonium molybdate into sulphuric acid solution is an effective way to prevent the occurence
of green color in the mixtural solution.When the acidity of sulphuric acid solution
ranges from 3.32 to 8.55 mol L-1H2SO4,it has no effect upon the quality of prepared
mixtural reagent. |
