Effect of the near-infrared activated photocatalyst $ Cu_{2} $(OH)$ PO_{4} $ nanoparticles on the growth of harmful algal blooms causing Microcystis aeruginosa
Abstract The wide range existence of M. aeruginosa FACHB 905 strains in the aquatic environment becomes a great threat for the health of humans and animals; it also poses a great obstacle in the ecological ecosystem. Therefore, an effective, efficient, and environmentally friendly method of treatment is needed. In this work $ Cu_{2} $(OH)$ PO_{4} $ nanoparticles were successively synthesized from a mixture of Cu ($ NO_{3} $)2 and $ Na_{2} $$ HPO_{4} $ according to the results from Fourier-transform infrared (FT-IR), X-ray diffraction (XRD), ultraviolet/visible/near-infrared in diffuse reflectance spectroscopy (UV/Vis/NIR DRS), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS) tests. Furthermore, $ Cu_{2} $(OH)$ PO_{4} $ was used to mitigate the growth of M. aeruginosa FACHB 905 strains on a lab-scale, and the investigation on the growth of the harmful algal bloom (HAB) causing M. aeruginosa FACHB 905 strains was worked on. The $ Cu_{2} $(OH)$ PO_{4} $ is effective in inhibiting the growth of the strain by more than 97% at a concentration of 0.032 mg $ mL^{−1} $. Furthermore, analysis of the chlorophyll a content and polysaccharide asserted that a remarkable decrease from 9.40 mg $ L^{−1} $ and 37.66 mg $ L^{−1} $ for the control to 0.07 mg $ L^{−1} $ and 10.21 mg $ L^{−1} $ for the treatment media with 0.032 mg $ mL^{−1} $ $ Cu_{2} $(OH)$ PO_{4} $ has been achieved. The results affirm the effectiveness of the $ Cu_{2} $(OH)$ PO_{4} $ as suitable candidates for preventing HABs caused by the M. aeruginosa FACHB 905 cyanobacterium and other similar strains..
