Hybrid humic acid/titanium dioxide nanomaterials as highly effective antimicrobial agents against gram(-) pathogens and antibiotic contaminants in wastewater.

摘要: Abstract Humic acids (HAs) provide an important bio-source for redox-active materials. Their functional chemical groups are responsible several properties, such as metal ion chelating activity, adsorption ability towards small molecules and antibacterial through reactive oxygen species (ROS) generation. However, the poor selectivity instability of HAs in solution hinder their application. A promising strategy overcoming these disadvantages is conjugation with inorganic phase, which leads to more stable hybrid nanomaterials tuneable functionalities. In this study, we demonstrate that humic acid/titanium dioxide nanostructured materials prepared via a versatile situ hydrothermal display activity against various pathogens behave selective sequestering agents amoxicillin tetracycline antibiotics from wastewater. physicochemical investigation combination techniques were utilized, included TEM, BET, 13C-CPMAS-NMR, EPR, DLS SANS, shed light on structure-property-function relationships nanohybrids. The proposed approach traces technological path exploitation organic biowaste design at molecular scale multifunctional nanomaterials, useful addressing environmental health problems related water contamination by pathogens.
