| dc.description.abstract | Nowadays, mining and electroplating industry are the most significant source of water pollution. Heavy metals pollutant which releases into environment, have resulted in various environmental impacts. In this study, adsorption of Zn2+ onto the adsorbent (KOH-treated, HCl-treated, and untreated sugarcane bagasse) was examined. During the removal of Zn2+ process, the batch technique was used and the effect of pH of the solution, the adsorbent dosage, initial concentration of Zn2+ and contact time were investigated. The optimum conditions for the highest percent removal of Zn2+ of 76% were achieved at pH 5, 1.0 g adsorbent dosage, contact time of 90 min and 100 mg/L initial concentration of Zn2+ solution. The maximum adsorption capacity was 8.80 mg/g after 90 minutes contact time with an initial concentration of 250 mg/L, 1.0 g adsorbent dosage and optimum pH of 5.0. Data obtained from batch adsorption experiment fitted well with the Langmuir isotherm model. The adsorption kinetic followed the pseudo-second-order equation which demonstrated a chemisorption process between sugarcane bagasse and Zn2+. The characterisation studies were performed using Fourier Transform Infrared Spectroscopy (FTIR). The major functional groups found in the sugarcane bagasse is CO stretch. KOH-treated sugarcane bagasse before adsorption has higher functional group C=O stretch, C=C stretch, C-H bending and O-H stretch compare to untreated sugarcane bagasse before adsorption. It was concluded that the KOH-treated sugarcane bagasse had higher adsorption capacity for Zn2+ compared with the HCl-treated and untreated sugarcane bagasse. The KOH-treated sugarcane bagasse was an inexpensive and environmentally friendly adsorbent for Zn2+ ions removal from aqueous solutions. | en_US |
