Abstract

The comparison of phenol adsorption with activated carbon from coffee residue has been conducted. The first step in this study is coffee residue activation with ZnCl2 in 85oC during 7 hours. The coffee residue was dryed in 24 hours at 110oC and after that it was dissolved by activated carbon with 10% HCl and pH neutralized by using aquades 65oC. The activated carbon was determinate at pH 2-6, with time 15-60 minutes and phenol concentration 2-10 mg/L. From that result would be processed with isotherm Freundlich’s equation. The optimum conditions result obtained at pH 4, time 30 minutes and adsorption capacity of 1.733 mg/g. The activated carbon has been used into waste samples which have addition of phenol and obtained result 2.4751 mg/L from 6.4778 mg/L for waste water A. W. Sjahranie hospital and 0.0560 mg/L from 2.0068 mg/L for Karang Mumus River.Keywords: Phenol, adsorption, activated carbon, coffee residue
