Adsorption kinetics of victoria blue onto perlite

Abstract

The effects of various experimental parameters such as initial dye concentration, temperature and pH on adsorption capacity of victoria blue on perlite have been investigated. The extent of dye removal increased, with the increase in initial concentration, pH and temperature of the dye and contact time. Adsorption measurements show that the process is fast and the adsorption data were modeled using the first order kinetic equation. The results indicate that perlite could be employed as a low cost alternative to commercial adsorbents in wastewater treatment for the removal of colour and dyes. The activation energy was calculated as 2.4 kJ/mol.
