Removal of titanium dioxide nanoparticles by coagulation ...

To investigate the possibility of removing titanium dioxide nanoparticles (TiO2 NPs) from water by coagulation, as well as to find the optimal coagulant and experimental conditions for TiO2 NP removal, four types of coagulant were adopted: polyferric sulfate (PFS), ferric chloride (FeCl3), polyaluminum chloride (PACl), and alum (Al2(SO4)3). It was found that the removal of TiO2

The buildings that clean our air - TDMA - Titanium Dioxide ...

When used in a particular way, titanium dioxide’s ability to remove pollutants directly from the air offers a huge opportunity in the fight to cut pollution levels. This is particularly relevant in cities, which have both high levels of pollution and a huge number of buildings. There are limitations to using titanium dioxide on surfaces in the fight against local air pollution, but it can be ...

Removing Oxide Coating From Titanium - Products Finishing

01.12.2006  Titanium oxide is extremely stable and difficult to remove when formed. It cannot be removed by typical heat treatment (i.e., like a bright annealing of a stainless steel to remove heat tint and other oxidation products). Although I have not tried it, one chemical recipe I have seen for cleaning titanium is a mixture of nitric acid at about 40% by volume and hydrofluoric
