| This research represents a novel approach of water treatment using photocatalytic carbon nanotubes (CNTs) with antimicrobial properties to combat the problems associated with infectious microorganisms in drinking water. The synthesized TiO2/CNT was achieved by a proprietary electrochemical deposition method conducted in a 3- electrode setting, TiO2/CNT as the working electrode, Ag/AgCl: 3M KCl as the reference electrode and platinum counter electrode. Cyclic voltammetry (CV) was performed at various scan rates to vary the morphology of the coating and this was characterized using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDX), Thermo-gravimetric Analysis (TGA) and Raman spectroscopy. In addition, the photosensitivity of TiO2/CNT was also tested.;This TiO2-CNT was used to study the bactericidal growth rate of six different strains of gram positive (Bacillus substilis, Staphylococcus aureus and Staphylococcus 1 epidermis) and gram negative (Escheridia coli, Klebsiella pneumonia and Pseudomonas aeruginosa). These data will be utilized in the development of a water treatment system and for future advancement in water treatment science and technology which is becoming increasingly important in the face of pending water shortages. |
