Abstract

Abstract

Adsorption character and conditions of the five colorants on three different kinds of adsorbent (polycaprolactam powder,active carbon,anion exchange resin)were systematically investigated.Elution behavior of seven inorganic anions was also studied.The results shows that all the three kinds of adsorbent can be used for preseparation of seven inorganic anions in the five synthetic colorants.Recoveries are 95%~105% and matrix interference in ion chromatography is eliminated effectively.
