摘要：

K+ doped graphitic phase carbon nitride sludge-based composite (AC/K-CN) was prepared by calcination method using flocculation sludge of water-based ink wastewater, melamine and potassium carbonate as raw materials. The crystal structure, morphology and photoelectric properties of the composite were characterized by XRD, UV-Vis DRS, FTIR, XPS, BET, SEM and PL. The composite was applied to remove cationic blue X-GRRL from aqueous solution under visible-light irradiation. The results showed that the photocatalytic activity of AC/K-CN on cationic blue X-GRRL was higher than that of pure graphite phase carbon nitride (g-C3N4) or carbonized sludge (AC), which is attributed to the effective electron-hole separation of the composite. Compared with AC and pure g-C3N4, AC/K-CN composite increased the degradation rate of cationic blue X-GRRL with a mass concentration of 20 mg/L by 43.17% and 46.76% under simulated sunlight. © 2020, Editorial Office of FINE CHEMICALS.
