文摘

Porous poly(glycidyl methacrylate) (PGMA) was prepared via water-in-oil (W/O) emulsion polymerization and was grafted with thiol groups. The removal of mercury (Hg) ions from water was evaluated using the functionalized PGMA. First, PGMA was synthesized and functionalized. Then, FTIR was used to assess the bonding of thiol groups with PGMA. SEM was used to analyze the porous characteristics of the material. To determine the effect of the pH on the Hg adsorption to functionalized PGMA, Hg adsorption tests were performed by varying the solution pH from 2 to 10. Additionally, a Hg adsorption test was performed by changing the initial Hg concentration.
