Herein, a novel and comprehensible approach has been
suggested to degrade the emerging micropollutants such as synthetic dyes. In
this study, a continuous UV-C irradiation has been used to treat the aqueous
matrix of synthetic pollutant dyes under highly alkaline environment (pH
>13.0). In this HA-AOP, the treatment rate and degradation efficiency are
primarily found to be affected by the type of pollutant dye present in the
matrix, concentration of XOH or pH and UV-C fluence rate. In addition, the
kinetic study indicates that HA-AOP or UV-C/XOH(X=Na or K) process follows zero
order reaction kinetics during the degradation of parent pollutant species. The
explored approach is quite auspicious due to its tremendous potential to handle
versatile aqueous matrices containing natural organic materials, inorganic
salts, fatty matters, surfactants and many more things. Overall, unlike other
AOPs, this novel UV-C/XOH(X=Na or K) based HA-AOP could be highly utilized for
the effective treatment of various alkaline wastewater streams.
