| Abstract: | The research work of certified reference material for ZnS powder of infrared optical purpose was introduced. Based on the ZnS raw material, the certified reference material was prepared by purification method. After the homogeneity and stability were examined, the value of SO4 2- content was determined by ion chromatography. Three kinds of sulfate content certified reference material included three grades in the range of 0.1% to 0.5%, with the relative expanded uncertainties no more than 2% （k =2）. |
