Abstract

The main objective of this study is to investigate the kinetic sorption of humic acid (HA) from aqueous solution onto the polyvinyl di fluoride Nano fiber. Batch adsorption experiments were carried out using HA solution as an adsorbate under variety of concentration in the range of 20-100 mg/L. It was observed that the amount of humic acid adsorbed decrease with an increase in the HA concentrations. The kinetic experimental data proportionally correlated with the pseudo-second-order kinetic model with a rate constant in the range of 0.024-0.065 g mg-1 min-1.
