Abstract :
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.
