Immobilization of laccase on chitosan functionalized halloysite nanotubes for degradation of Bisphenol A in aqueous solution: degradation mechanism and mineralization pathway.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
As a hazardous organic chemical raw material, Bisphenol A (BPA) has attracted a great deal of scientific and public attention. In this study, the chitosan functionalized halloysite nanotubes immobilized laccase (lac@CS-HNTs) was prepared by simultaneous adsorption-covalent binding method to remove BPA for the first time. We optimized the preparation of lac@CS-NHTs by controlling one-factor variable method and response surface methodology (RSM). The cubic polynomial regression model via Design-Expert 12 was developed to describe the optimal preparation conditions of immobilized laccase. Under the optimal conditions, lac@CS-NHTs obtained the maximum enzyme activity, and the enzyme loading was as high as 60.10 mg/g. The results of batch removal experiment of BPA showed that under the optimum treatment condition, the BPA removal rate of lac@CS-NHTs, FL and heat-inactivated lac@CS-NHTs was 87.31 %, 60.89 % and 24.54 %, respectively, which indicated that the contribution of biodegradation was greater than adsorption. In addition, the relative activity of lac@CS-NHTs dropped to about 44.24 % after 8 cycles of BPA removal, which demonstrated that lac@CS-NHTs have the potential to reduce costs in practical applications. Finally, the possible degradation mechanism and mineralization pathway of BPA were given via High-performance liquid chromatography (HPLC) analysis and gas chromatography-mass spectrometry (GC-MS) analysis.
