Evaluation of the potential of agricultural waste products for the treatment of textile dye contaminated water

Abstract

In this study, the peels of waste agricultural products (banana, orange, potato) used as biosorbent in order to remove textile dyes from aquatic solutions. Biosorption of the commonly used textile dye such as Acid Red P-2BX (AR) was investigated by the peels of different agricultural products. The waste peels of banana, orange and potato were prepared as dried and ash biosorbent. The effects of pH, biosorbent type, dye concentration, biosorbent dosage and temperature on dye biosorption were tested at batch scale level. The best removal of dye was performed by the banana peel. Biosorption by dried banana peel for AR dye was found to be 73.58% at optimum conditions. It was concluded that dried banana peels were effectively used in the treatment of textile dye- contaminated water.
