Adsorption of Copper Ions from Water via Sorption Materials from Agricultural Wastes
公开Exposure to high levels of dissolved heavy metals can lead to significant health risks and effective methods of filtering water are needed. One method used for removing heavy metals from water is the use of sorption materials derived from agricultural waste. These materials include activated carbons, glucose hydrochars, CELF lignins from poplar, maple and bagasse, and subcritical water extraction coffee waste. It was found that the glucose hydrochars, the maplewood and bagasse lignins had the ability to absorb a small amount of copper ions. The other materials caused the test solutions to become discolored, rendering the UV spectroscopy readings inconclusive. Activating the glucose chars using pyrolysis increased the adsorption capacity and eliminated the slight colorization.
