| Abstract: | Aluminophosphate zeolite (AlPO4-5)
coated or impregnated by clusters of TiO2 were prepared under
hydrothermal conditions (Temperature, ~150°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. |
