Flower-like Co3O4/C3N5 composite as solid-phase microextraction coating for high-efficiency adsorption and preconcentration of polycyclic aromatic hydrocarbons and polychlorinated biphenyls in water

Sensitive detection of environmental pollutants that are harmful to organisms is of great significance for prevention of related diseases. In this work, a flower-like Co3O4/C3N5 composite as solid-phase microextraction fiber coating was developed for extraction of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). The Co3O4/C3N5 composite was derived from the multilayer stacked flower shaped Co(OH)2/C3N5 that …
