“…After 15 min of reaction, a phenol removal efficiency equal to 79%, 100%, 98%, 100%, 100% and 100% was obtained in the case of phenol, 4-methyl phenol, 4-chlorophenol, 2,5-dimethyl phenol, 2,4,6-trimethyl phenol and 2,4,6-trichlorophenol, respectively. Horová et al [77] obtained the complete removal of phenol by wet peroxide oxidation. In particular, they used iron modified zeolites as a catalyst, and a reaction time of 5 h.…”
