Abstract
Abstract
Pectin isolated from orange kisar (Citrus sp) peel has been used as phenol adsorbent. The ability of the pectin as phenol adsorbent was examined at several contact times, pHs, and phenol concentrations. Determination of phenol adsorption was carried out by UV-Vis spectrophotometry method. The optimum conditions of phenol adsorption by the pectin were obtained at the contact time of 20 minutes, pH 3.0, and phenol concentration of 25 ppm. Phenol adsorption by the pectin follows the nonlinear model of the Freundlich adsorption isotherm with the correlation coefficient (r2), Freundlich’s constant (KF), and indicator of concentration dependence (n) were 99.51%, 0.6439 (mg/g) (L/mg)(1/n), and 1.620, rescpectively.
