Development of Bio-Degradable Adsorbent Having Nano-Size Molecular-Recognition Sites and Actual Clean-Up and Analysis of an Aqueous Environment

Abstract

We have to develop an adsorbent for the sake of removing nitric acid and phosphoric acid from natural river water to reduce this environmental problem. Although only a small amount of the adsorbent was applied to a river, 81 of nitric acid and 52 of phosphoric acid were removed from the natural river water continuously for 3 months.
