Abstract

The removal of metanil yellow dye was studied through adsorption on meosporous aluminophosphate molecular sieves at different experimental conditions like contact time, pH, dye concentration and adsorbent dosage. The experimental values were adopted to adsorption kinetic and adsorption isotherm equations for understanding the rate and mechanism of adsorption process. The adsorption process was well fitted with pseudo first second kinetics and Langmuir adsorption isotherm. The maximum adsorption capacity of metanil yellow on adsorbent was 75 mg/g. This study concludes that the mesoporous aluminophosphate material is a good material for removal of metanil yellow dye.
