Remediation of Cr(VI)using C₃N₄/DEU-51(Fe)under sun light irradiation
Abstract
A hybrid nanocomposite namely C₃N₄/DEU-51(Fe) was developed to reduce the Cr(VI) from a textile industry wastewater. C₃N₄/DEU-51(Fe) exhibited a good cristalinity. The photocatalytic reaction of the carboxyl groups of the composite is in center and it is associated with the C-H-vibration. The optimal doping content of C₃N₄/DEU-51(Fe) was determined to be 1.2 mg/L to treat 1.6 mg/L Cr(VI) with a maximum yield of 98% at a sun light power of 80 mW/m2 after 15 min at 42 °C in summer. After 5th times sun light experiments, the C₃N₄/DEU-51(Fe) was reused with a yield of 97%. The Cr(VI) reduction was explained with the Langmuir-Hinshelwood (L-H) kinetic model.
