Some end users are concerned about the content of P,Fe and K in hydrogen peroxide products.An analysis method of P,Fe and K contents in hydrogen peroxide products by inductively coupled plasma emission spectrometer was proposed.Firstly,standard addition method was used to determine the content of P in the product,and the spike recovery test was carried out at the same time.The contents of Fe and K in the product were determined by standard method,at the same time,the standard deviation of Fe and K and the conformity of detection limit of the method were verified.Secondly,the influence factors and solutions in the experiment were proposed.Experiment results showed that: the contents of P,Fe,K and other trace elements in hydrogen peroxide products were analyzed by inductively coupled plasma emission spectrometer.The comprehensive advantages of this method are obvious.
