Determination of Phosphorus in Iron Phosphate by Continuous-flowing Analyzer Method
Phosphorus in iron phosphate was detected by continuous-flowing analyzer,and compare with HG/T 4701-2021 method.The results showed that the phosphorus concentration was linear with the absorbance in the range of 0 μg/mL to 200μg/mL and the linear correlation coeffi-cient r was 1.0000,the recovery rate is from 99%to 101%.There is no significant difference in both methods.
