| Abstract: | In this paper,the process of determining the content of phosphorus using Phospho\|vanado\|molybdate method is reported.The phosphorus in mixed fertilizers is extracted via neutral ammonium citrate solution and reacting with ammonium molybdate(in HNO 3 solution)to produce a yellow complex substance.The content of phosphorus is determined by differential spectrophotometry at 420nm. |
