Using a cationic adsorbent, I was able to remove an anion and a cation at the same time in my research. I used a cationic polymer gel to remove arsenic (both arsenate and arsenite) and manganese at the same time utilizing adsorption. When I started this endeavor, my research goal was to remove only arsenic. However, after successfully removing the two most common forms of arsenic in the environment, arsenate and arsenite, I went on to conduct studies utilizing cationic polymer adsorbent to remove manganese. I investigated the removal of cadmium using the same adsorbent after simultaneous removal of arsenate, arsenite, and manganese. Cadmium was also successfully removed. This breakthrough of removing anion and cation concurrently with a single adsorbent is groundbreaking because it has never been done before.

使用阳离子吸附剂，我能够在我的研究中同时去除阴离子和阳离子。我使用阳离子聚合物凝胶去除砷（砷酸盐和亚砷酸盐）和锰，同时利用吸附。当我开始这项奋进时，我的研究目标是只去除砷。然而，在成功地去除了环境中两种最常见的砷形式，砷酸盐和亚砷酸盐后，我继续进行利用阳离子聚合物吸附剂去除锰的研究。我研究了镉的去除使用相同的吸附剂后，同时去除砷酸盐，亚砷酸盐，锰。镉也被成功清除。这种用单一吸附剂同时去除阴离子和阳离子的突破是开创性的，因为它以前从未做过。
