| Abstract: | This paper mainly studie the contents determination of organic phosphorus and inorganic phosphorus in the organic phosphate synthesis by lanthanum nitrate precipitation titration, in order to monitor the reaction, the seperation and the purification. This method is fast, simple and convenient, with high accuracy. Inorganic phosphorus and organic phosphorus in the organic phosphate synthesis are analyzed by ammonium phosphomolyb date spectorphoto metry and La~(3 ) titration. The conparasion of the two methods show that the results of determination are basically equal. |
| Keywords: | La~(3 ) Precipitation titration Organic phosphorus Inorganic phosphorus |
