Treatment of paper wastewater by palm kernel shell-based activated carbon adsorption

Abstract

In this study, removal rates of phenol which causes toxic and impurities were investigated in the paper industry wastewaters using the adsorption technique. Palm shell activated carbon (PSAC) was used as adsorbent in the all experiments. Variables such as the contact time, the dose of adsorbent was chosen as the parameter. In the result of experiments, pH 6, an hour's time and 3 g/L adsorbent dose were found to be suitable for optimum removal. In these circumstances, removal was obtained in 70.58 % rate of phenol. The obtained experimental data were described with a linear regression model. In addition, when specifying explained both Langmuir model of phenol adsorption process with isotherm studies, I. order kinetic model showed that a better fit II. order kinetic model for PSAC of phenol adsorption event with kinetic studies
