Titanium dioxide pigments

Graphite / Titanium Dioxide Composite

Nanosized titanium dioxide (TiO2) in its anatase form is the most frequently studied and as well as used photocatalyst. There are several syntheses procedures which enable to achieve photocatalytic TiO2. The solgel method utilizing titanium alkoxides is used most often. Alternative precursors such as titanium tetrachloride and titanyl sulphate are also frequently employed. Nowadays the environm...

Investigation photocatalytic removal efficiency of phenol in Shadegan pond by thin layer of titanium dioxide nanoparticles sensitized with natural pigments

Phenolic compounds, such as phenol, are found to be significant in agricultural and industrial wastewater, especially in petroleum and petrochemical industries. Since these industries make up a large share of foreign exchange earnings, we have ignored from the huge contamination of them. we produces a large amount of wastewater from these industries and dispossessed them without proper purifica...

Titanium Dioxide in Sunscreen

Titanium dioxide has been used in various industrial and cosmetic applications due to its unique elemental properties. This substance has a refractive index higher than most other compounds (n = 2.6142, in comparison to water at 20°C n = 1.33). This allows titanium dioxide to have an iridescent and bright quality. It has been used in the cosmetics industry for “whitening” and “thickening” in mu...

Carcinogenicity Assessment of Titanium Dioxide

Introduction Titanium dioxide is a white mineral that is used to color paints, plastics, paper and other materials and is approved by the FDA as both a direct (with restricted uses) and indirect food additive. It is a non-genotoxic poorly soluble particulate. As such it has been found to not cause cancer by various routes in a number of animal models except for the rat. Titanium dioxide, as wit...
