摘 要:本文以甲基丙烯酸为原料制备多孔聚丙烯酸水凝胶,并将其用于吸附水中的Cu2+,该实验主要考察了pH、溶液中Cu2+的初始浓度和吸附时间对多孔聚丙烯酸水凝胶的吸附性能的影响。结果表明,水凝胶吸附Cu2+的主要影响因素是pH和Cu2+初始浓度,当Cu2+溶液pH为7时,溶液中Cu2+初始浓度为5g/L时吸附效果最佳。27845 毕业论文关键词:多孔聚丙烯酸水凝胶;吸附;铜离子
Study on The Adsorption Properties of Porous Polyacrylate Hydrogel to Cu2+ in Water
Abstract:In this paper,acrylic acid as raw material to prepare porous polyacrylate hydrogel adsorbent,And or the adsorption of Cu2+ in wastewater,the experiment of pH,Cu2+ initial concentration,adsorption time,the initial amount of substance Cu2+.Effect of adsorption was the amount of substance of the porous polyacrylate hydrogel.The results show that,pH and Cu2+ concentration are the main factors affecting the adsorption of Cu2+ hydrogel,when the solution pH is 7,when the initial concentration of Cu2+ solution is 5g/L,there is the best adsorption effect.
Key Words: Porous polyacrylate hydrogel;Adsorption;Copper ion
