Pollution caused due to the leaching of heavy metal ions in aqueous environment has become a real concern in the present scenario. Therefore, purification of drinking water before consumption is essential for maintaining a healthy life. Among various approaches employed for this purpose, filtration by membranes and adsorption on specific substrates have been found to be two very promising techniques due to their efficiency, ease of operation, cost effectiveness and requirement of low operational space. A large variety of materials have been utilized to date in fabricating these membranes and adsorbents. However, it has been observed very recently that filtration membranes and adsorbents containing aromatic conjugated polymers (ACPs), polyaniline and polypyrrole in particular, exhibit superior metal ion removal efficiency. Such membranes and adsorbents also possess high surface areas and charge and site density within their structure to attract and attach metal ions. Herein, the recent research activities involved in the fabrication and utilization of ACP-containing membranes and adsorbents for the removal of heavy metal ions from wastewater are summerized.

芳烃共轭聚合物用于去除废水中的重金属离子：简短评论

在当前情况下，由于重金属离子在水性环境中的浸出而引起的污染已成为真正的问题。因此，饮用前净化饮用水对于维持健康生活至关重要。在用于该目的的各种方法中，由于膜的过滤效率和操作简便性，成本效益以及对操作空间小的要求，已经发现通过膜过滤和在特定基材上的吸附是两种非常有前途的技术。迄今为止，已经在制造这些膜和吸附剂中使用了各种各样的材料。然而，最近已经观察到，包含芳族共轭聚合物（ACP），特别是聚苯胺和聚吡咯的过滤膜和吸附剂表现出优异的金属离子去除效率。这样的膜和吸附剂在其结构内还具有高的表面积以及电荷和位点密度，以吸引和附着金属离子。在此，涉及用于从废水中去除重金属离子的含ACP的膜和吸附剂的制造和利用的最新研究活动是夏季化的。
