APPLICATIONS OF BRAZILIAN ILLITE-KAOLINITE IN NATURAL AND INTERCALATED FORMS AS ADSORBENTS TO REMOVAL OF ZINC FROM AQUEOUS SOLUTIONS: KINETIC AND THERMODYNAMIC STUDIES

The capability of natural and modified-Illite/kaolinite for zinc adsorption from aqueous solution was investigated in the present paper. The new hybrid material was composed of the natural clay using the intercalation process with dimethyl sulfoxide. The objective of this study was to examine the ad...
