Textile and clothing industry effluents are a major source of water pollution, and it is important to filter these effluents to prevent contamination. This study introduces the use of carbon-based membranes coated with graphene oxide (GO) and reduced graphene oxide (RGO) on cellulose surfaces for efficient dye filtration. The results show high filtration rates of 98% and 94% for methylene blue and rose bengal dyes, respectively, making it an eco-friendly method for treating industrial dye-contaminated water.
Textile and clothing industry effluents are the primary source of water pollution, affecting aquatic animals and plants. The need of the hour is to filter these effluents to avoid contamination. Nanofiltration using carbon-based membranes is an effective method in dye filtration. The present work describes graphene oxide (GO) and reduced graphene oxide (RGO) coated cellulose surfaces for dye filtration. These sheets exhibited high porosity, large surface area, high flexibility, inexpensive, easy to fabricate, and successfully employed for efficient nano dye filtration. The novelty of the present work is the filtration of most industrially used dyes such as methylene blue and rose bengal. Results confirm the filtration up to 98% and 94% for both Methylene Blue (MB) and Rose Bengal (RB) dyes, respectively, and the eco-friendly mode of treating industrial dye-contaminated water.
