Removal of phenols and aromatic amines from wastewater by a combination treatment with tyrosinase and a coagulant.
TL;DR: Results indicate that the combination of tyrosinase and a cationic polymer coagulant is effective in removing carcinogenic phenols and aromatic amines from an aqueous solution.

Removal of phenols from wastewater by soluble and immobilized tyrosinase
TL;DR: An enzymatic method for removal of phenols from industrial wastewater was investigated and immobilized tyrosinase, immobilized by using amino groups in the enzyme on cation exchange resins, can be used repeatedly.

Effects of peat humic acids on the catalytic oxidation of pentachlorophenol using metalloporphyrins and metallophthalocyanines
TL;DR: In this paper, the effects of peat humic acids (HAs) on PCP oxidation were investigated using HP-β-cyclodextrin as a model for the hydrophobic portions in HAs.
