Acid Green 25 removal from wastewater by organo-bentonite from Pacitan
Source abstract
Abstract
The capability of surfactant modified-bentonite for adsorption of dyestuff from aqueous solution was investigated. The so-called "organo-bentonite" was obtained by modifying the raw bentonite obtained from Pacitan, Indonesia using cetyl trimethylammonium bromide (CTAB) and later employed as adsorbent for Acid Green 25 removal. Isotherm and kinetic experiments were carried out on three different temperatures (30, 40 and 50 °C). Langmuir and Freundlich models were chosen for isotherm equilibria data correlation, of which the former showed better suitability. On kinetic data representation, pseudo-first and second order models were used, with the last model gave better correlation.
