Wastewater treatment by aminated peroxidase in alginate hydrogel

Abstract

Phenols are highly toxic organic compounds found in wastewater due to various industries’ pollution. Its removal is of great importance for human and animal health. Enzymatic wastewater treatment has several advantages over traditional methods. Enzyme immobilization onto solid carriers enables its reusability and lowers the cost of treatment. In this work, immobilized horseradish peroxidase on chemically modified alginate hydrogel was tested for phenol removal. The reusability of the tested immobilizate was monitored in repeated cycles. After five consecutive cycles, the remaining activity of the immobilized enzyme was 54%. The obtained result shows the potential for using this immobilizate for wastewater treatment.
