ABSTRACT

The aim of this investigation is to determine the adsorption behavior of chromium (VI)
on Tuncbilek activated carbon sample. The effects of the Cr concentration (25-100 ppm),
temperature (297-325 K) and pH (2.5-9.8) on adsorption were investigated systematically. It
was found that the effectiveness sequence of the parameters was initial Cr(VI) concentration,
temperature and pH. Increasing the pH from 2.5 to 9.8 causes a decrease in adsorption. But
it is obvious that adsorption was increased by increasing the initial Cr concentration and
temperature. The multilinear mathematical model was also developed in this study to predict
successfully the Cr adsorption values of activated carbon within the experimental conditions.
