Photocatalytic disinfection of and degradation of natural organic matters in river water using titanate nanotubes.

In this study, we synthesized and modified titanate nanotubes (TNTs) under different conditions of acid rinsing and calcination. The produced materials were then characterized by transmission electron microscopy, X-ray diffraction, ultraviolet-visible spectroscopy, temperature programmed desorption, inductively coupled plasma atomic emission spectroscopy, and Brunauer-Emmett-Teller analysis. The activity of material was evaluated via its application for disinfection of and removal of natural organic matters (NOMs) in river water.
