Abstract

This study use composite ZnO/Ca3(PO4)2 material was synthesized by using the sol-gel method. Composite material ZnO/Ca3(PO4)2 is made from beef tailbone which is heated at a temperature of 300  for 10, 90, 120, and 240 minutes. Samples were characterized using X-ray diffraction ( XRD ), Fourier transforms infrared ( FTIR ) dan UV - Visible ( UV-Vis ). Quantitative analysis of XRD spectra showed the lowest crystal size with a diameter of 21.71 nm on heating for 90 m. The results of the FTIR spectrum show the vibration of the PO4 and ZnO bond at wavenumber 1039 cm-1 and 400-500 cm-1. The best percentage of degradation is indicated by small crystal size and high infrared absorption by O-H bonds. The degradation results reached 93.98% in just 5 minutes with an energy gap of 3.84 eV. Based on these results, the ZnO/Ca3(PO4)2 composite is one of the promising and potential catalyst materials to solve the problem of industrial waste pollution, especially methylene blue.

Abstract

ZnO/Al2(SO4)3 synthesized by mechanical alloying method (1, 10, and 15 hours) was applied as methylene blue (MB) photodegradation. Fourier transform infrared (FTIR), X-Ray Diffraction (XRD), and Uv-Visible (Uv-Vis) were used to characterize the Physico-chemical properties of the composites. The results of XRD and FTIR characterization showed an average crystal size of 50.02 nm and the lowest transmittance value (%) at 10 hours milling, the degradation efficiency was much influenced by crystallinity speed, functional groups, and milling time. In this study, the optimal degradation based on the results of the Uv-Vis was shown by the sample ZnO/Al2(SO4)3 for 10 hours milling with a degradation percentage of 84.87%. Furthermore, it was found a ZnO/Al2(SO4)3 composite with a very short degradation time of 20 minutes. In order to reduce water pollution in environments, composite based on natural material is a promising solution due to their ability to break up pollutant radical compounds bonding.
