Aqueous pollutants of cesium, iodide, lead, zinc and chromate ions adsorbed on natural and Ag+(Pb2+) – or NH4+- exchanged clinoptilolite together with surfactant hydrophobized, Ca-alginate pelletized as well as MnOx – and FeO(OH) – clinoptilolites compared with the inland montmorillonite were assessed. The investigations of zeolites (clinoptilolite type) for the removal of various kinds of aqueous pollutants incl. radioactive ones lead to the conclusion that this natural resource can be considered for an alternative cost-effective adsorption material, either with or without surface treatment, depending on the type of water to be purified.

具有表面增强功能的斜发沸石,用于去除放射性核素和无机污染物

铯、碘化物、铅、锌和铬酸根离子吸附在天然和Ag + (Pb 2+ ) - 或NH 4 + - 交换的斜发沸石以及表面活性剂疏水化、海藻酸钙颗粒以及MnOx - 和FeO(OH ) – 评估了与内陆蒙脱石相比的斜发沸石。沸石(斜发沸石型)去除各种水污染物的研究,包括。放射性研究得出的结论是,根据要净化的水的类型,可以考虑将这种自然资源用作具有成本效益的替代吸附材料,无论是否经过表面处理。
