Abstract

The synthesis and Rhodamine B removal efficiency of monazite monoclinic BiPO₄ by hydrothermal route using Bi(NO₃)₃·5H₂O, K₂HPO₄·3H₂O and HNO₃ as staring materials were presented in this work. The obtained samples were characterized by X-ray powder diffraction, high-resolution transmission field-emission scanning electron microscopy and diffuse reflectance UV-Vis spectrometry. The results showed that, by selecting suitable reaction parameters, the pure monazite monoclinic phase of BiPO₄ was received readily at hydrothermal temperature as low as 130 ^oC, considerably lower than that reported previously. The obtained monazite monoclinic phase of BiPO₄ powders exhibited a high removal efficiency of 96% for 150 min under 365nm-UV irradiation. The mechanism of the Rhodamine B photodegradation reaction over the synthesized monazite monoclinic BiPO₄ was also proposed.
