Abstract:A method of FIA(Flow Injection Analysis) employed to measure the phosphorus content in the technological process of numid-phosphorue acid has been described in this paper. This mixture of ammonium molybdate and ammonium vanadate is served as a developer and a solution 0.48 molL~(-1) hydrochloric acid as the carrier steam, in the method, which has been applied to the acid-solution and the extracted residual solution. The content of phosphorus ranging from 0 to 500rag/1 is able to be determined with satisfied results, which can be printed out directely directly by a computer. The datas obtained from the method are in agreement with those from the neutral titration.
