With the change of environmental impacts and pollutants, the amount of heavy metal ions found in water bodies have increased. These heavy metal ions pose risk to both the environment and humans because they can bioaccumulate in the environment. In order to remediate waters contaminated with heavy metals, a safe and effective removal process must be found. Napthoquinone sulfonic acid (NQSA) semicarbozone (SC) and thiosemicarbozone (TSC) ligands are attached to anion exchange resin beads to create chelating resins. The removal of two heavy metal ions will be studied using the chelating resins to determine their effectiveness at removing the ions from solution at two environmentally relevant pH values. A dry weight distribution, D<sub>w</sub>, value is calculated to measure the amount of metal removed from the solution. It is anticipated NQSA-SC and TSC resins will provide an effective means of remediating metal ions from aqueous sources.
