Abstract

Aluminophosphate zeolite (AlPO4-5) coated or impregnated by clusters of TiO2 were prepared under hydrothermal conditions (Temperature, similar to 150 degrees C; Pressure is autogenous). These composite materials were subjected to a systematic characterization using X-ray diffraction, Fourier transform infrared spectroscopy, Scanning electron microscopy and BET surface area measurements. The encapsulation of TiO2 in the AlPO4 zeolite framework was confirmed by the profile analysis of X-ray diffraction patterns. The resultant products were employed successfully in the degradation of Indigo carmine dye. The effect of pH and the efficiency of composite materials on the degradation of Indigo carmine dye have been worked out. The decrease in the chemical oxygen demand proved the decomposition of harmful organics present in the dye solution.
