Abstract
Micropollutants are a growing concern regarding contamination of groundwater resources. Heavy metals such as cadmium are steadily increasing in concentration in various natural water sources. These heavy metals seep into drinking water and is very difficult to remove via normal commercially available filtration methods. These pollutants are non biodegradable; implying that they accumulate in living tissue which leads to the problem of biomagnification. Thus, they possess a threat to the ecosystem. Existing treatment methods in wastewater plants are insufficient to remove heavy metals. There is a significant need to invent cheap and effective methods for micropollutant/heavy metal removal. These methods should also preferably use biological agents instead of chemical ones. In this work, the adsorption of cadmium in biochar and water hyacinth has been analysed and compared.
