Various strategies have been developed for the removal of synthetic dyes from the
wastewater of the textile industry due to their stability as well as their negative effect on the
environment. Enzymatic wastewater treatments as environmentally safe processes have many
benefits. An enzyme suitable for use in the treatment of wastewater from the textile industry
is horseradish peroxidase (HRP) because it can degrade different types of dyes. Immobilized
enzymes have many advantages over free enzymes in solution such as higher stability and the
opportunity to be removed easily from the reaction mixtures. Consequently, immobilized
enzymes can be used more than once. Many different materials are used as a carrier for
enzyme immobilization, so if residual material is used as a carrier, waste valorization will be
achieved. In this study immobilized commercial HRP was used for decolorization of
anthraquinone dye Acid green 40 (AG 40). Waste material – potato peels were used as a
carr...ier for the immobilization of HRP. Potato peels were oxidized with sodium periodate to
introduce aldehyde groups that can react with the primary amino groups of the enzyme to
form Schiff bases, resulting in covalently immobilized HRP. The success of the oxidation
was verified by the 2,4-dinitrophenylhydrazine (DNPH) test, and subsequently, the oxidized
potato peels were characterized by SEM and FTIR. After oxidation, the influence of the mass
of the immobilization carrier on enzyme activity and immobilization efficiency was
investigated. The optimal conditions of pH, hydrogen peroxide concentration, concentration
of AG 40, and enzyme activity were determined for decolorization of AG 40 with
immobilized HRP. Adsorption of AG 40 on the carrier was also determined. In addition, the
operational stability of the enzyme was determined. The results obtained show that oxidized
potato peels are a promising material that can be used as a carrier for the immobilization of
HRP.
