Özet: Adsorption is a preferred method for the removal of dyes from aqueous solutions. In this study, Adsorption of Direct Red BWS obtained from the textile plant onto the peanut shell was investigated. Temperature, initial dye concentration, initial pH, and adsorbent dose were selected as affecting parameters for adsorption. S/N (Signal/Noise) values were calculated and the effective level of the parameters were determined using Taguchi L9 orthogonal array. Then, Analysis of Variance (ANOVA) has been used to identify the significant parameters. The study revealed that initial pH was the most effective parameter followed by initial concentration, adsorbent dose, and temperature. The temperature is found to be the least significant parameter in adsorption experiments. The optimum levels of parameters are temperature 23 oC, initial dye concentration 150 mg.l-1, initial pH=2.5 and, adsorbent dose 50 mg respectively and adsorption capacity is qe=50.57 mg.g-1.
