Validation of the Method for Testing the Penetration Performance of Liquid Cations(Li+、Na+、K+、Mg2+、Ca2+)in Protective Materials Using Ion Chromatography
Based on the national standard GB/T 23462-2009,this article conducts method verification on the test method for determining the permeability of liquid cations(Li+,Na+,K+,Mg2+,Ca2+)in protective materials by ion chromatography.The main content of the verification includes the standard curve,method detection limit,precision,and accuracy.Then,it conducts actual sample measurements according to the applicable scope of the standard.The verification results show that the linear relationship,detection limit,precision,accuracy,and uncertainty of the standard curves of Li+,Na+,K+,Mg2+,and Ca2+all meet the basic requirements of GB/T 27417-2017,and the laboratory's technical capabilities meet the technical index level required by this standard method,and this standard method has applicability and operability.
