以水溶液中Cu(Ⅱ)为吸附对象,考察了合成的β-环糊精微球(β-CDPs)对Cu(Ⅱ)的吸附性能.研究了p H值、吸附温度、吸附时间、吸附剂用量及共存离子和离子强度等条件对β-CDPs吸附性能的影响,同时考察了β-CDPs的再生性能.最后,进行了β-CDPs对实际水样中Cu(Ⅱ)的吸附分析.结果表明,合成的β-CDPs在最佳条件下对Cu(Ⅱ)具有良好的吸附性能,β-CDPs对Cu(Ⅱ)吸附率最大可达87.45%,且可再生使用.将该微球用于实际水样中Cu(Ⅱ)的吸附研究,对电镀废水的最大吸附率为68.10%,对游泳馆废水的最大吸附率可达77.50%.
The adsorption properties of Cu (Ⅱ) on β-cyclodextrin microspheres (β-CDPs) were studied by using Cu (Ⅱ) as adsorbent in aqueous solution. The effects of p H value, adsorption temperature, adsorption time, And the influence of coexisting ions and ionic strength on the adsorption properties ofβ-CDPs were studied.At the same time, the regeneration performance ofβ-CDPs was investigated.Finally, the adsorption analysis of Cu (Ⅱ) The synthesized β-CDPs had good adsorption properties to Cu (Ⅱ) under the best conditions, and the adsorption rate of β-CDPs to Cu (Ⅱ) was up to 87.45% In the sample Cu (Ⅱ) adsorption study, the maximum adsorption rate of electroplating wastewater was 68.10%, and the maximum adsorption rate to the swimming pool wastewater was 77.50%.
