Inactivation of escherichia coli under fluorescent lamp using TiO2 nanoparticles syntesized via sol gel method (Penyahaktifan Escherichia coli di bawah Lampu Pendarfluor menggunakan Nanozarah TiO2 yang Disintesis melalui kaedah Sol Gel)

Titanium dioxide nanoparticles were synthesized by using sol gel method and their physico-chemical properties were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and UV-Vis spectrophotometer. The photocatalytic propert...
