The result showed that the optimal condition of inorgano-absorbent manufacture as following: concentration of vitriol is 15%, the bentonite carrier must be soaked in the 0.4% La(superscript 3+) solution, the pH is 10, microwave radiation power is 340 W for 5 min. The optimal condition of organo-absorbent manufacture process as following: concentration of CTMA is 5%. The rate of wave must 166 W and the time of radiation is 6 mi In addition, the experimental results showed that with inorgano-absorbent the pH number is 3~6 and the reaction time is 45 min, the removal efficiency of phosphor will be up to 99% and the amount of adsorption will be up to 41 mg/g.
