Pollution of phenol compounds is a serious problem for the environment. Phenols are toxic and hazardous materials because they have high toxicity in water causing disturbance to aquatic ecosystems and human health. Biosorption is a simple and efficient method to solve the problems caused by phenol compounds. Biosorption is a process of absorbing solids derived from natural materials that can bind to compounds in a solution. The biosorption method used is batch using banana peels (Musa balbisiana Colla) as biomass. Optimization of parameter for the absorption of phenol compounds studied are pH and concentration. The results show that optimum conditions at pH 4 obtained with the absorbed concentration of 1.82 ppm and the optimum concentration of 50 ppm. The analysis of phenol compounds absorption is measured by using a spectrophotometer UV-Vis at a maximum wavelength of 265 nm and for the characterization of biosorbents is determined by using FTIR.
