Chlorophenolic compounds are persistent contaminants commonly observed in contaminated soil and groundwater due to their high toxicity and low biodegradability. While the classical homogenous Fenton process suffers from high operating costs and excessive sludge formation, heterogeneous Fenton processes show a viable, cost‐effective solution to the oxidative dehalogenation of chlorophenolic compounds due to the use of solid‐based catalyst materials with much lower chemical costs and less sludge production. The catalyst materials used in the heterogeneous Fenton degradation of chlorophenols include monometallic iron materials (e.g. Fe oxides/sulfides, zero‐valent iron), multimetallic iron composites, and iron catalysts with support material. This chapter covers an extensive review of papers regarding the applicability of heterogeneous Fenton processes to the treatment of chlorophenolic compounds under different operating conditions, including catalyst type, size, and dose, chlorophenol type, pH, H2O2 requirements, and reactor configurations. In addition, reaction intermediate species and their biodegradability are discussed.
