| Abstract: | For fast analysis, the influences of co-existing components on P-V molybdenum yellow colorimetry method used to determine P content in N-P compound chemical fertilizer were tested; tests were also done for comparison of P-V molybdenum yellow colorimetry method and molybdophosphoric acid quinoline weight method. The method of P-V molybdenum yellow colorimetry was set up for determination of water soluble P and effective P in N-P compound chemical fertilizer. This method is simple, fast and accurate, water soluble P and effective satisfying central control analysis, also suited to the determination of P in phosphoric acid-ammonium. |
