Simultaneous Determination of Trace Silicon,Phosphorus and Arsenic as Heteropoly Acids with Rh6G by Spectrophotomtric Method Combined with Computer |
| |
| Abstract: | The optimum conditions were studied for silico phospho and arseno molybdic heteropoly acids to form ion associates with RH6G in the presence of polyvinyl alcohol.A spectrophotometric method has been established that can determine simultaneously trace Si,P,and As by means of solving super coupled equations with a computer.A computer program has been designed and applied to determine Si,P and As in carbon steel.The results are reliable. |
