摘要
Abstract
Divalent cations such as calcium ions in water can cause a certain hardness. A novel super-absorbent polymer with three-dimensional network and strong adsorption capacity was prepared by water solution copolymerization of acrylic acid (AA) and acrylic amide (AM). The resin was chosen as the adsorbent to remove hardness from hard water samples as 3 mmol/L as calcium ion. The removal property was assessed by investigating treatment of hard water with different amount of poly (acrylic acid) resin. The results show that the maximum adsorption amount of the resin is 108 mg/g, the adsorption rate of the resin increases with the increase of the amount of resin. The resin generally removes more than 76. 2% of the calcium ion from the tested water samples. This method provides water softening with a new techuplogy reference due to its widely resource and environment-friendly property.关键词
