Abstract
Nowadays, the shortening in accessibility of safe drinking water is a matter of worldwide concern due to various contaminants released into water bodies from industrial, human and animal sources, including microbial pathogens, which can be of greatest health concern. The use of chemical reagents like chlorine and ozone for disinfection of drinking water is widespread but results in disinfection byproducts (DBPs) that are carcinogenic and harmful to human health. Thus, the search for biosustainable alternatives to target this problem is of utmost relevance. For instance, cellulose-based biological raw materials have been used in different adsorbents for water treatment. In a similar fashion, the aim of this work is to employ biomass raw materials and hybrid materials to prepare bactericidal visible-light nanoporous composite materials. The idea is innovative and can result in low cost, effective treatment of water in areas of high risk of contamination around the globe. The composite materials will be obtained via metal-doping of exfoliated clay material prepared from a combination of Kaolinite clay and agro waste biomasses using the solvothermal method. The process is meant to develop new materials that have the ability to generate Reactive Oxygen Species (ROSs) for disinfection of pathogen-loaded water (AU)
