    Status of arsenic contamination in the groundwater of nawalparasi west district and Remediation Using ZnCL2 Activated sugarcane bagasse as bioadsorbent
    (2024-06) Ghimire, Khag Raj; : Dr. Bhoj Raj Poudel
    Groundwater sources contaminated by arsenic represent a global threat to the environment and living organisms, including humans. Exposure to arsenic for a long period would have a severe health impact. Various conventional techniques are being applied to treat arsenic contaminated water, which are either expensive or less efficient. So, there is a need to develop cost-effective alternative technologies for the removal of arsenic. This research will investigate the possibility of using agro-waste like sugarcane bagasse as a readily available, affordable, eco-friendly bioadsorbent for remediation of toxic pollutants from water. The main target of this study is to develop a novel adsorbent from sugarcane bagasse by ZnCl2 activation. As it is reported that Nawalparasi West district in Lumbini Province has a high concentration of arsenic in ground water, the performance of bio-adsorbent will be examined by 30 different samples from arsenic contaminated area of Nawalparasi. The material which will be developed in this research from sugarcane bagasse is supposed to be efficient and selective for specified arsenic. The batch experiment will be carried out under varying experimental conditions. The kinetics of the adsorption reaction and the adsorption isotherm will be studied. The experimental results will be applied to the treatment of ground water samples from Ramgram municipality, Nawalparasi west district.
