Comparative Assessment of the Graphene Oxide and Reduced Graphene Oxide Influence on the Zeta Potential of Selected Bacteria in Drinking Water Environment

摘要

Microbial adsorption to solid surfaces plays a fundamental role in bioengineering, food processing,environmental protection, medicine and medical biotechnology as well as power industry and water filtration [1]. It is generally accepted that nanomaterials are providing great opportunity to develop bioactive sorbent materials which can be used as electrodes in fuel cells as well as separation media in water purification to remove inorganic and organic pollutants from contaminated water. They offer a number of advantageous physicochemical properties. On a mass basis,they can be characterized by much larger surface area and surface bioactivity than their bulk counterparts [2]. Nanomaterials can also be functionalized with various chemical groups which allow selectively targeting key biochemical constituents of waterborne bacteria and viruses [3].
