制备了一种新型的钙-海藻酸钙包埋BaSO4-CR(CABSC)杂化吸附剂。通过对两种阴离子染料和两种阳离子染料吸附性能的考察，研究了它们的吸附选择性和吸附机理。采用间歇吸附技术研究了两种阳离子染料(EV和MB)在水溶液中的吸附行为。考察了时间、pH、温度和离子强度对吸附的影响。此外，该材料还用于处理两个实际的阳离子染料废水。我们的研究表明，该吸附剂在染料废水处理过程中具有潜在的应用前景。
A new hybrid adsorbent of calcium-alginate encapsulated BaSO4-CR (CABSC) has been prepared. The adsorption selectivity and mechanism were studied by investigating the adsorption performance of two anionic and two cationic dyes. The adsorption of two cationic dyes (EV and MB) from aqueous solutions was examined using a batch sorption technique. The effects of time, pH, temperature and ionic strength on the adsorption were examined. Besides, this material was applied in the treatment of two practical cationic dye wastewaters. Our study shows that the sorbent could be a potential candidate for utilization in dye wastewater treatment processes.
