Study on the Adsorption Effect of ZnCl₂-Modified Pomelo Peel Powder on Wastewater Containing Pb (II)

Abstract:

The modified pomelo peel powder was prepared by using chemical modification methods of ZnCl₂ soaking and heating.The removal rate of Pb (II) ion in simulation of wastewater by the modified pomelo peel powder was tested. The effects of pH of wastewater, initial concentrations of Pb (II) ion, adsorbent dosage,temperature and time on adsorption of Pb (II) ion was studied. Results show that when Pb (II) ion initial concentration at 100 mgL^-1, pH of wastewater at 3.5-5.5, adsorption time at 100min, adsorbent dosage at 15gL^-1, temperature at 35°C, the removal rate of Pb (II) ion in simulation of wastewater by the modified pomelo peel powder was more than 95%.
