The study describes the bacth experiment on technical diret red dyes removal from aqueos solution which use cellulose acetat prepared from Ananas comosus leaves. The Adsorption investigations were carried out in various of time, adsorbent mass, adsorbate concentration, and temperature. The adsorption kinetics followed a pseudo second order reaction. The equilibrium adsorption data was best presented by the Freundlich isotherm. The calculated thermodynamic parameters indicate that the ongoing adsorption process was endothermic and non-spontaneous in nature.
