摘要
Abstract
Objective] To establish a method for the rapid determination of the phosphorus in feed-grade phosphate.[Method]The concentration of phosphorus in phosphate was determined by spectrophotometry method .Different types of feed-grade phosphate samples were detected and compared by national standard method.[Result] The optimized detection condition was as follows: 420 nm detection wavelength, 0.5 -1.0 mol/Lchromogenic acidity, color developing temperature greater than 15 ℃, and 20-30 min color developing time.Under this condition, the recovery rate was 97.5%-100.1%.The results of two methods all met the requirement of standard.[Conclusion] Phosphorus content in feed-grade phosphate detected by spectrophotometry method is proved to be easy, rapid and accurate.关键词
