METHOD FOR PRODUCING ABSORBENTS

摘要

This organic adsorbent is used for recovering or removing heavy metallic ions. The mixed organic material is composed of polymer which is dissolved in the solvent, and trioctylphosphine oxide dissolved in acetone, and mixing mixture of the two compounds of the volume ratio of 1:0.5-2. The paste produced with this mixture is drying at 15-60 deg.C for 5-60 min., dipping the solid body such as rashing ring into the paste or spraying the surface of the solid body with them, and removing the solvent. The adsorbent is dipping in the water.
