| Research Abstract |
A COMPOSITE OF TITANIUM PHOSPHATE-POROUS CARBON WAS PREPARED FROM AMINO PHOSPHATE CHELATE RESIN BY ADSORBING TI(IV) AND CARBONIZATION AT 773 K AND 873 K. THE COMPOSITE HAD POTENTIAL FOR ADSORPTION AND DECOMPOSITION OF ORGANIC COMPOUNDS IN WATER. REMOVAL OF METHYLENE BLUE IN THE AQUEOUS SOLUTION WAS CONDUCTED BY A BATCH TEST WITH IRRADIATION OF BLACK LIGHT. PLATINUM WAS ADDED INTO THE COMPOSITE AS PROMOTOR. CRYSTALLINE TIP2O7 AND METALLIC PT WERE FOUND IN THE COMPOSITE. THE DIAMETERS OF THESE CRYSTALLINE PARTICLES WERE LESS THAN 30 NM. PT PROMOTED GASIFICATION OF THE POLYMER CHAIN OF THE CHELATE RESIN.
THE REMOVAL RATE OF METHYLENE BLUE WAS INCREASED BY CO-EXISTING PT. THE REMOVAL RATE CONSTANT K WAS EXPRESSED BY FIRST ORDER KINETICS. THE REMOVAL RATE CONSTANT PER WEIGHT OF TI IN THE COMPOSITE K' WAS ALMOST CONSTANT EVEN THOUGH PT CONTENT WAS INCREASED.
