▎ 摘  要

NOVELTY - Photodegradation catalyst comprises 35-50 pts. wt. multi-element compound base material, 10-15 pts. wt. compound polymeric ferric sulfate, 3-5 pts. wt. polyacrylamide, 8-12 pts. wt. 3% dimethyl sulfoxide aqueous solution, 3-5 pts. wt. sodium persulfate, and 10-15 pts. wt. triethanolamine. The preparation of the photodegradation catalyst comprises (i) mixing the multi-element compound base material and polyacrylamide uniformly and adding it into the 3% dimethyl sulfoxide aqueous solution, heating in a water bath at 45-60 degrees C and stirring for 15 minutes at 150-180 revolutions/minute to obtain mixed solution A; and (ii) mixing the compound polymeric ferric sulfate and triethanolamine uniformly to prepare mixture B, adding mixture B into mixture A, adding sodium persulfate, and stirring at constant speed for 40-60 minutes. USE - The catalyst is useful for organic sewage treatment (claimed). ADVANTAGE - The catalyst has excellent photocatalytic activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing photodegradation catalyst, comprising mixing the multi-element compound base material and polyacrylamide uniformly and adding it into the 3% dimethyl sulfoxide aqueous solution, heating in a water bath at 45-60 degrees C and stirring for 15 minutes at 150-180 revolutions/minutes to obtain mixed solution A, mixing the compound polymeric ferric sulfate and triethanolamine uniformly to obtain mixture B, adding mixture B into mixture A, adding sodium persulfate, and stirring at constant speed for 40-60 minutes.
