Abstract

Rice husk ash (RHA) product was chemically modified and utilized for the adsorption of toxic dye from water. The textile dye (crystal violet) was removed from aqueous media using Rice Husk Ash (RHA) and Chemically Modified Rice Husk Ash (CMRHA) as adsorbents. The effects of stirring time, dye concentration, adsorbent dose, pH and temperature on the adsorption capacity were studied. The chemical modification of RHA enhanced the absorption efficiency from 88.9% to 99.1% at pH 6 and room temperature by using 2g/L of adsorbents. Thermodynamics study indicated that the process is exothermic and spontaneous. The kinetics study indicated that the adsorption process for the two adsorbents best fitted to the pseudo-second order kinetics model. The equilibrium data were tested with Langmuir, Freundlich, and Temkin equations. It was investigated that data best fitted to the Langmuir and Temkin models, which indicated for chemisorptions process and heterogeneous surface of the adsorbents.
