摘要
以丙烯酸β-环糊精酯共聚物为吸附剂,采用分光光度法测定该吸附剂对亚甲基蓝和碱性品红溶液的静态吸附效果,考察了吸附时间、体系pH值等对吸附量的影响。结果表明:常温下,亚甲基蓝的较佳吸附条件为静态吸附时间约7h、体系pH=8.0时,最大吸附量达到166.3mg/g;碱性品红的较佳吸附条件为静态吸附时间约7h、体系pH=10时,最大吸附量达到137.9mg/g。该共聚物对亚甲基蓝染料吸附性能更好。
The static adsorption of adsorbent for Methylene Blue and Fuchsin Basic were determined by spectrophotometry with acrylic acid-β-cyclodextrin esters copolymer as adsorbent. Effects of adsorbing time, pH and temperature on adsorption amount of copolymer were studied . The results show thatthe optimum experimental conditions of adsorption at room temperature are as that adsorbance Q for Methylene Blue reached maximum 166.3 mg/g when absorbing time is 7 h and pH is 8.0, adsorbance Q for Fuchsin Basic reached maximum 137.9 mg/g when absorbing time is 7 h and pH is 10. So the copolymer has better adsorption properties for Methylene Blue than Fuchsin Basic.
