摘要
利用硝酸银溶液对D001大孔型磺酸基聚苯乙烯阳离子树脂进行浸渍处理,制备出硝酸银负载型阳离子交换树脂。将离子树脂作为载体,对水溶液中的溴离子进行吸附性能测试。通过改变吸附剂用量、吸附时间和吸附温度,探究不同吸附条件对吸附剂吸附水中溴离子性能的影响。结果表明:该吸附剂使用的优化条件为吸附剂添加量1 g、吸附时间40 min、吸附温度25℃。在该优化条件下,吸附剂对水中溴离子的吸附量为64.97 mg·g^(-1),吸附率可达99.96%。
The D001 macroporous sulfonate polystyrene cationic resin was used to prepare a silver nitrate load cation exchange resin.Taking the resin as the carrier,the adsorption properties of the bromine ions in the aqueous solution were tested.The influence of different adsorption conditions on adsorption of bromine ions was explored by changing the amount of adsorbent,adsorption time and adsorption temperature.The experimental results showed that the optimization conditions were as follows:the adsorbent 1 g,adsorption time 40 min,adsorption temperature 25℃.Under this optimization conditions,the adsorption amount of bromide ions was 94.97 mg·g^(-1),the adsorption rate was 99.96%.
