USE OF NATURAL AND MODIFIED KAOLINITE/ILITE AS ADSORBENT FOR REMOVAL METHYLENE BLUE DYE FROM AQUEOUS SOLUTION

In this study, the original interstratified kaolinite/ilite clay sample has been collected from altered basalt in Minas Gerais state, Southeast of Brazil. The natural sample was used in the intercalation process with dimethyl sulfoxide. The efficiency of the natural and modified kaolinite/illite cla...
