The excessive usage of herbicide in agricultural industry has known to cause unexpected side effects both on human and environment. This present study investigates the viability of using nano-Hydroxyapatite as a catalyst in the photodegradation of the herbicide Atrazine. Nano-hydroxyapatite (nHAp) was synthesized using cow bone as the calcium source via simulated body fluid (SBF). Physical and morphological characterization was done using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The SEM analysis results indicates the formation of globular precipitated nHAp with 22 to 114 nm particle diameter size. The FTIR and XRD results confirmed the presence of functional groups and crystal structure associated to presence of hydroxyapatite. The photodegradation of the Atrazine herbicide results showed a steady increase in efficiency with the increasing amount of catalyst and UV exposure time. The highest degradation efficiency of 52% was achieved with 0.7 g nHAp for 2.5 hrs exposure. This study showed that Atrazine herbicide can be effectively treated with the proposed method to reduce the environmental impact of the herbicide by converting it into potentially less dangerous by-products that can be less harmful.
