Disclosed is a method for treating phenol wastewater. The method includes the following step: adding a hydrophobic phthalocyanine as a catalyst, and H.sub.2O.sub.2 as an oxidant into the phenol wastewater. The hydrophobic phthalocyanine is obtained by decorating a hydrophobic group on a bacterial cellulose-metal phthalocyanine with a silane coupling agent; the bacterial cellulose-metal phthalocyanine is obtained by mixing a metal phthalocyanine into a bacterial cellulose medium, biologically culturing with an acetic acid bacterium, and then heating and reducing the mixture; and the metal phthalocyanine is nitro-sulfonic metal phthalocyanine.

Disclosed is a method for preparing a material of plant origin rich in phenolic acids, including at least one metal, including: preparing a material of plant origin chosen from: aquatic plants; materials rich in tannins; materials rich in lignin; and obtaining a material of plant origin, rich in phenolic acids, in which the ratio of the intensity of the vibration band of the CO bond of the COOH group and the intensity of each of the vibration bands the aromatic ring determined in FT-IR is between 0.5 and 4. The material of plant origin is brought into contact with an effluent including from 0.1 to 1000 mg/l of at least one metal, thus obtaining a material of plant origin rich in phenolic acids including from 1 to 30% by weight of at least one metal relative to the total weight of the material.

Disclosed is a method for preparing a solid material including manganese, the method including the following steps: a. bringing into contact an aqueous effluent including manganese, for example at least 5 mg/L, typically at least 5 to 50 mg/L, and preferably 7 to 25 mg/L of manganese, with an oxidizing agent, manganese, preferably at a temperature between 10 C. and 50 C., and obtaining an oxidized aqueous solution; b. adding a base to the oxidized aqueous solution obtained at the end of step a) until a pH of between 8 and 12, preferably greater than 9, and preferably from 9 to 10.5, and obtaining a solution including a precipitate; c. filtration of the solution obtained at the end of step b); and d. obtaining a solid material including manganese, and especially manganese (IV) and/or Mn (III).
