Degradation of 2,4-dichlorophenol by melamine amine cellulose- immobilized lacasses, TAPPI JOURNAL October 2017

ABSTRACT: Epoxidized dialdehyde cellulose (EDC) was prepared and grafted with melamine to obtain melamine grafted epoxidized dialdehyde cellulose (EDC-melamine); the products were characterized by various methods and were used as carriers to immobilize laccase. Results show EDC-melamine can immobilize laccase effectively and have higher enzymatic activity compared with EDC. Furthermore, the enzymatic activity of EDC-melamine was  found to be as high as 865 U•mg-¹, compared with 140U•mg-¹ for EDC. The removal efficiency of 2,4-dichlorophenol (2,4-DCP) for EDC-melamine immobilized laccase was about 71.5% at 40°C for 4 h at 10.0 mg•L-¹ and dosage of  laccase = 0.2 g/L. The removal efficiency can remain greater than 63%, even after six cycles.

Application: This topic provides a new method to immobilize laccases. The product can be used to treat  wastewater polluted by phenol and shows excellent performance.
