Abstract
The use of cheap, efficient and environmentally friendly adsorbents has served as an alternative source of carob in order to remove dye-stuffs from waste water. This study has researched the potential use of carob powder as alternative adsorbent for the removal of methylene blue from wastewater. Experiment parameters pH, ultrasonic frequency, particle size, contact time, temperature and initial concentration of dissolved methylene blue (MB) dye were investigated. Thereafter, Box-Behnken design experiment was applied the adsorption experiments. The equilibrium time was 267.63min for methelene blue dye. The results showed that physisorption seemed to play a major role in the adsorption process. The adsorption process of methylene blue on carob powder was found to rate of adsorption decreases with increasing temperature and the process exothermic. Regression analysis results demonstrated that is good for the experimental data to the non-linear model with correlation coefficients of (R2) value of 0.8899 and 0.9830. The maximum adsorption value was determined as 256,4355 mg/g. This result appears to be important when compared with other studies reported in the literature. According to the results of the study was observed carob bean can be used as an alternative adsorbent.
