Abstract

Background: Chromium is one of the toxic HEAVY METALS that exist in trivalent and hexavalent forms in aqueous systems. HEXAVALENT CHROMIUM is highly toxic, carcinogenic and corrosive in nature. Adsorption is an effective method in chromium removal. The aim of this study is investigation of the HEXAVALENT CHROMIUM removal using SUGARCANE BAGASSE from synthetic solutions and determining of the sorption kinetics.Methods: The impact of pH, temperature, contact time, Adsorbent concentration and paricle size on chromium removal was carried out. Langmuir and Freundlich adsorption isotherms with sorption kinetics were investigated. Experiments were carried out with Tagochi method using Qualitik4.Finding: The maximum chromium removal was achieved in pH=2, temperature of 50oC, 500 mm adsorbent size, adsorbent concentration of 20g/l equal to 90.1%. Altogether adsorption capacity was increased with increasing temperature and adsorbent concentration and decreased with increasing pH. Adsorbent particle size does not an important effect on removal efficiency. SUGARCANE BAGASSE ADSORPTION KINETICS in chromium removal followed by second- order reaction and were in good agreement with Langmuir isotherm.Conclusion: the results showed appropriate adsorption capacity for sugarcane baggase in HEXAVALENT CHROMIUM removal as a significant pollutant.
