Abstract

Because of the serious environmental issues associated with colorants in the current study, the elimination of Malachite Green dye was studied on different montmorillonite clays modified with ferric and titanium dioxide to produce sufficient low cost adsorbents under optimal operational parameters. The data on rate constant study were fitted on pseudo-first-order and pseudo-second-order model adsorption kinetics equations. Maximum Malachite Green dye removal molecules up to 88 and 99.6%, respectively was accomplished by adsorption of the dye molecules onto fe-modified montmorillonite and Tio2 immobilized on fe-modified montmorillonite clays at optimum conditions (pH=7, agitation time=150 min, amount of adsorbents=1g/L and initial MG concentration=50 mg/L). The kinetic adsorption study showed that for initial MG dye concentration 50 mg/L, pseudo-second-order kinetic is more favorable. More than 95% removal for Malachite Green dye showed that Tio2 immobilized on fe-modified montmorillonite clay is an effective promising compound and also inexpensive for treatment processes. The key benefits of this approach include high removal, simplicity, minimal dosage requirements, and high adsorbent adsorption capacity. After five consecutive cycles of regeneration of Tio2 immobilized on fe-modified montmorillonite clay, only a 2.1% reduction in MG removal efficiency was observed. Tio2 immobilized on fe-modified montmorillonite was found to be a highly innovative recyclable adsorbent for MG removal. The empirical correlation achieved the best fit of predicted% MG removal from (AS) using fe-modified montmorillonite clay, yielding the highest value (R2 = 0.992).
