Involvement of process parameters and various modes of application of TiO₂ nanoparticles in heterogeneous photocatalysis of pharmaceutical wastes – a short review

Abstract

In recent years, the occurrence of persistent organic compounds in industrial as well as municipal effluents is becoming a serious threat to the environment. The detrimental effects can be minimized with the help of photocatalysis.

Development of a mathematical model to predict different parameters during pharmaceutical wastewater treatment using TiO2 coated membrane

“…Several immobilization techniques are adopted to reuse and recycle the nano particles, among them immobilization of nano particle on the membrane surface has become promising technique (Sarkar et al, 2014b). Earlier studies have shown that membrane can be used for immobilization of foreign material to incorporate catalytic property on the membrane surface (Ho and Zydney, 2000;Nunes et al, 1996).…”

Influence of TiO2 morphology on the photocatalytic efficiency of direct Z-scheme g-C3N4/TiO2 photocatalysts for isoniazid degradation

“…In past decades, titanium dioxide (TiO 2 )-based heterogeneous photocatalysis has been used for the efficient degradation of organic compounds, dyes, pesticides and pharmaceuticals [1][2][3][4][5][6][7][8][9].…”

Photocatalytic degradation of sulfamethoxazole in visible irradiation using nanosized NiTiO 3 perovskite

“…Recently, Advanced Oxidation Processes (AOPs) based on generation of strongly reactive hydroxyl radicals ( * OH) have received a large interest for the removal of pharmaceuticals from waste water [8][9][10]. Among the AOPs, heterogeneous photocatalysis is considered as a promising process for pharmaceuticals active ingredients treatment operating under ambient temperature and pressure [11][12][13][14][15].…”
