| Abstract: | A fast practical determination method of phosphorus in titanic titanic of high content content titantium is reported in this paper. samples are solvated with nitric acid -ammonium fluoride,oxygenized with ammonium persulfate and extraced by ether. P(Mo2O7)6]7-direct spectrophdometry to determinate the microamounts of phosphorus. Compered with sereval other method,an excellent resrlt shows in the content rang of phosphours 0. 005-0. 0200%. This method ean be applied in the course of practical industrial production,the effect is satisfactory. |
