Micro-nano bubbles assisted laccase for biocatalytic degradation of bisphenols

Bisphenols are important industrial materials for example the production of plastics, but also well known their adverse health effects, in particular bisphenol A (BPA) is an endocrine disruptor. The widespread use plastics has raised concerns. Therefore, removal bisphenols from wastewater sparked interest scientific community. This work introduces a novel hybrid technique micro-nano bubbles assisted laccase (MNB-Lac) to degrade water. feasibility MNB-Lac using BPA as model contaminant was evaluated by comparing with MNB, Lac, ultrasound (UL), UL-Lac, and UL-MNB-Lac. Comprehensive investigations were carried out understand specific influences key process parameters including initial pollutant concentration, temperature, air intake, pH, outlet pipe length, Lac concentration on degradation. alkaline environment extended length could improve degradation efficiency further. exhibited 2.3–6.2 folds higher less time than other above under optimal parameters. mechanism revealed that generation hydroxyl radical, high O2 solubility, mass transfer induced MNB play roles enhancing catalyzed Lac. successfully used treating B, C, mixture three efficiency. Subsequently, these products analyzed GC–MS. potentially represents innovative technology considerable advantages cleanup phenolic contaminated Furthermore, findings provide new insights into enhancement performance oxidizing enzyme introducing technology.
