Summary, etc. <p><span>Pine needle biochar (PNB) has been examined as a promising cost-effective adsorbent using batch method for mitigation of Malachite green (MG) dye from synthetic wastewater. The effects of time of equilibration, equilibrium </span><em>p</em><span>H, dye concentration and temperature have been studied on adsorption of malachite green. Adsorption kinetics of MG onto PNB conformed to pseudo-first-order reaction. Adsorption of the dye onto PNB fitted well to Freundlich isotherm model indicating that multilayer adsorption and adsorption capacities (K</span><span>F</span><span>) are the highest (6837.40 mg/kg) at </span><em>p</em><span>H 7.0, intermediate (4073.61 mg/kg) at </span><em>p</em><span>H 9.0 and minimum (1196.05 mg/kg) at </span><em>p</em><span>H 4.6. Adsorption of malachite green regularly increased with increase in temperature. The evaluation of thermodynamic parameters indicate that adsorption of MG onto PNB was a spontaneous and endothermic reaction with increase in the disorderliness of the system. Fourier transformed infra-red spectroscopy (FTIR) studies indicate involvement of H-bonding and electron exchange between aromatic nuclei and electron donor groups onto PNB.</span></p>
