A novel method was developed for phenol degradation and the regeneration of phenol-saturated granular activated carbon (GAC) in bench-scale tests. The degree of phenol degradation in solutions was as high as 75.3% when using persulfate/electrochemical/FeCl2 (PS/Electro/Fe) system under optimal conditions (1000 mg/L Na2S2O8 and 500 mg/L FeCl2 at 15 V). Based on these results, the regeneration of phenol-saturated...
A new method of ultraviolet light (UV) activated persulfate (PS) oxidation was investigated to regenerate granular activated carbon (GAC) in drinking water applications. The improvements in iodine and methylene blue numbers measured in the GAC after ultraviolet- (UV) activated persulfate suggested that the GAC preloaded with natural organic matter (NOM) was chemically regenerated. An experimental...
