Carbon disulfide-modified pine needle as a novel biosorbent was investigated to remove Cu2+ from aqueous solution in batch experiment.The results indicated that when the solution pH was 7.0,adsorbate dosage was 0.4g,contact time was 60min,100mL wastewater containing 50mg/L Cu2+,the removal rate of material was 94.7%.The kinetic adsorption process of Cu2+ on pine needle modified by carbon disulfide was mainly ion exchange adsorption.Langmuir equation could simulate the material process of isothermal adsorption of Cu2+,indicating its adsorption was monolayer adsorption.
