Abstract
In order to solve the increasingly serious problem of printing and dyeing wastewater pollution, a kind of novel, efficient, and reusable spunlaced viscose/polyaniline-ZnO/GO fibrous membrane was fabricated in this work. Specifically, spunlaced viscose/polyaniline conductive fibrous membrane was firstly prepared by in-situ growth method, followed with the growth of zinc oxide (ZnO) and graphene oxide (GO) via the hydrothermal route to obtain spunlaced viscose/PANI-ZnO/GO fibrous membrane (SV@PANI-ZnO/GO membrane). The results show that the decolorization rate of SV@PANI-ZnO/GO membrane for methylene blue (5.0 mg/L) was 97.4% within 120 min, and the decolorization rate remained above 76.7% after five cycles. Moreover, the reaction process conformed to a quasi-first order kinetic model with the apparent rate constant of 0.0209 min–1. Meanwhile, the free radical capture experiment revealed that the main reactive species in the decolorization process was .OH. This work may provide a new method for designing photocatalytic materials for environmental applications.
