Adsorption has been widely applied in wastewater treatment for heavy metal removal. Due to the high cost of adsorbent materials, various types of materials including agricultural, industrial wastes and naturally abundant materials have emerged as low-cost adsorbents in recent years. However, enhancement processes need to be developed to improve the adsorption capability of the raw materials. It is still a challenge to find an economic material with high adsorption capacity. This paper demonstrates a strategy to activate a recycled waste material using a simple activating process, while significantly improving the adsorption capacity of cadmium from wastewater.

使用来自废印刷电路板的二元位点离子交换材料去除有毒镉

吸附已广泛应用于废水处理以去除重金属。由于吸附材料成本高昂，近年来出现了包括农业、工业废物和天然丰富材料在内的各种材料作为低成本吸附剂。然而，需要开发增强工艺以提高原材料的吸附能力。寻找具有高吸附能力的经济材料仍然是一个挑战。本文展示了一种使用简单的活化过程来活化回收废料的策略，同时显着提高了废水中镉的吸附能力。
