| چکیده | ||
| In the present study, Hydrilla verticillata biomass was investigated as a novel biosorbent for the uptake of basic dye malachite green from its aqueous solution. Kinetic and equilibrium studies were carried out in batch process. Batch adsorption experiments were conducted to study the effect of pH, temperature, sorbent dosage, initial dye concentration, and contact time for the removal malachite green dye. The dye uptake was maximum for the initial pH of 8, temperature of 30oC, sorbent dosage of 0.55g, initial dye concentration 200mg/l and contact time – 150 min. The kinetic studies were well modeled using pseudo first order and second order with isotherm studies. | ||
