固定化漆酶纤维素纳米晶复合水凝胶的制备及其除污性能的研究
Preparation of Immobilized Laccase Cellulose Nanocrystal Composite Hydrogels and Their Decontamination Properties
摘要
Abstract
Water pollution has become a major challenge in contemporary environmental management,causing not only significant economic losses but also posing threats to human production and daily life.Among various pollutants,recalcitrant phenolic compounds are particular problematic due to their high chemical oxygen demand,high toxicity,and chemical stability.Furthermore,their inhibitory effects on microbial activity future increase the difficulty of wastewater treatment.Traditional homogeneous catalysts suffer from drawbacks such as low catalytic activity,sludge generation,and non-reusability.Hydrogels,featuring unique three-dimensional network structures,demonstrate high pollutant removal efficiency and excellent recyclability,and thus have been widely used in wastewater treatment.Enzymatic catalytic treatment methods,characterized by high catalytic efficiency,mild reaction conditions,low requirements for wastewater quality and equipment,and reusability,also provide significant advantages in wastewater treatment.In this work,laccase was incorporated into a three-dimensional network structure of hydrogels via polymerization reactions.By introducing cellulose nanocrystals to modulate the permeability and mechanical properties of the hydrogels,a heterogeneous hydrogel catalyst is prepared.The study investigated the effects of various components on hydrogel properties and analyzed the degradation efficiency of laccase-cellulose nanocrystal hydrogel toward four typical organic phenolic compounds.It summarized relevant technical parameters to provide guidance for hydrogel-based heterogeneous catalysts.关键词
