Lanatus)}, volume={14}, url={https://journals.nust.ac.zw/index.php/zjst/article/view/150}, abstractNote={<p>This study focuses on investigating the effectiveness of water melon rind in phenol removal from aqueous solution. The effects of various parameters (pH, initial phenol concentration, biosorbent dosage and contact time) on phenol adsorption were investigated. The pH of 2, initial phenol concentration of 40 mg/L, biosorbent dosage of 0.6 g and contact time of 6 h also deduced to be the optimum conditions for the adsorption process. The maximum phenol removal under optimized conditions was 85%. The sorption data fitted to the Freundlich isotherm with a regression coefficient of 0.9824. The kinetics was best described by the intraparticle diffusion model and Elovich equation with regression coefficients of 1 and 0.8461 respectively showing that the reaction is chemisorption on a heterogeneous surface and the intraparticle diffusion rate only is the rate determining step. The study revealed that water melon rind have a potential of removing phenol from industrial wastewaters. </p>}, number={1}, journal={Zimbabwe Journal of Science and Technology}, author={Chigondo, Fidelis and Matara, Mathias and Zulu, Laurencia and Nyamunda, Benias C. and Chigondo, Marko and Chipise, Liberty}, year={2022}, month={Dec.}, pages={92–99} }
