摘要：PURPOSE:To recover inexpensively the adsorption performance of an anion exchange resin in a simple operation by bringing the anion exchange resin deteriorated by treating the waste water contg., phenol into contact with an aq. alkali soln. CONSTITUTION:An anion exchange resin wherein the adsorption performance of phenol is decreased by using it as an ion exchanging agent and performing repeatedly the adsorption and the desorption of phenol alternately is brought into contact with an aq. dilute alkali soln. such as an aq. caustic soda soln. in the ordinary temp. In such a way, the adsorption performance of phenol is economically recovered by a simple operation and the recovering yield of phenol is increased and this adsorbent can be used for a long period.
