Removal of Basic Red 2 from Industrial Effluents Using Natural Iraqi Material

Abstract

The use of natural Iraqi porcellanite as a cheap, abundantly and ecofriendly adsorbent has been studied as an alternative substitution of activated carbon for the removal of dye from industrial wastewater. This material was successfully used to remove the basic red 2 dye from aqueous solution in a batch equilibrium adsorption technique.

Various factors such as adsorbent dose, contact time, pH, initial dye concentration and particle size of adsorbent were taken into account at room temperature, and promising results were obtained.

The well known Langmuir and Freundlich isotherm models were applied for the equilibrium adsorption data and the various isotherm parameters were evaluated. The monolayer saturation capacity for adsorption basic red 2 was found to be 66.22 mg/g adsorbent.
