Removal of Cr(VI) from acid wastewater by BC/ZnFe2O4 magnetic nanocomposite via the synergy of absorption‐photocatalysis

The tensile testresults showed that the MF resins modified with BG and PVA improved the tensile strength of theimpregnated paper. In comparison with pure kraft cellulose paper laminates, the aramid paper corelaminates displayed comparatively higher tensile strength. Antifouling test results indicated that modifiedMF resin laminates had no obvious change while the MF resin laminate was stained. Thermal stability ofthe modified resins was investigated by thermogravimetric (TG) analysis and the results showed that thechar yield of modified MF resin was higher than that of the unmodified MF resin due to the addition ofBG. The modified MF resin laminates exhibited better flame retardancy properties through the analysis oflimiting oxygen index (LOI), vertical burning and cone calorimetry (CONE) compared to the MF resinlaminate. In addition, the flame retardancy of laminates was further enhanced when prepared with corematerials of aramid paper.
