The research is to explore the properties of poly (2-hydroxyethyl methacrylate), namely pHEMA, when treated with bases, acids, and select metal salts (1M condition). Perchlorate Cu(II) and Ni(II) salts yield the largest swelling, while acetate and sulfate have a negative effect. In 0.1M condition, the anionic impact is moderate, although perchlorate salts still display a little increased swelling. Perchlorate effect is also pronounced from perchloric acid, confirming enhanced swelling effect resulting from the perchlorate anion. Chelating modality was investigated by FT-IR. The interaction of pHEMA with Cu(II) salts led to the formation of a new band at 1632 cm-1. Florescence study also indicates that the Cu(II) strongly quenches the intensity of pHEMA’s emission, while Ni(II) only gives a mild quenching. The recycling capability is confirmed by reconditioning in water to remove the metal ions and the obtained gel can be used to uptake metal ions again.
