| Abstract: | The arsenic and heavy metal element lead in food additives ammonium dihydrogen phosphate have been determined by the inductively coupled plasma atomic emission spectrometry(ICP-AES) method. The best measurement conditions were studied by conducting experiments. The standard curve method was used to do quantification. The standard addition recoveries were 98.12%~99.54%. The relative standard deviations (RSDs) were 0.33%~1.2%. The detection limits were 0.010 76~0.035 05 mg/L. The method has the advantages of simplicity, fast speed and good reproducibility. |
