Toxicity assessment of anatase and rutile ,

Titanium dioxide nanoparticles (TiO 2 NPs), in the two crystalline forms, rutile and anatase, have been widely used in many industrial fields, especially in cosmetics Therefore, a lot of details about their safety issues have been discussed by the scientific community Many studies have led to a general agreement about TiO 2 NPs toxicity, in particular for anatase form, but no ,...

US3701417A

To remove a colored titania impurity from kaolin clay, the impure clay is formed into a well-deflocculated aqueous slip A small amount of a soluble source of polyvalent cations, eg, calcium chloride, is dissolved in the slip An anionic organic polyelectrolyte is added and the slip is agitated until titaniarich flocs form and settle out from the deflocculated slip...

Smoluchowski coagulation equation

In statistical physics, the Smoluchowski coagulation equation is a population balance equation introduced by Marian Smoluchowski in a seminal 1916 publication, describing the time evolution of the number density of particles as they coagulate (in this context "clumping together") to size x at time t Simultaneous coagulation (or aggregation) is encountered in processes involving ....

water treatment

The scope of flocculation with sludge contact is immense: clarification, specific precipitations (carbonate removal, silicon removal,), colour removal, iron or manganese removal, clarification as part of pre or post treatment in aerobic or anaerobic biological water purification treatment...

Preparation of TiO2 nanoparticle from Ti

On the other hand, floc precipitation efficiency was better for TiCl4 if compared with FeSO4 The optimum concentration of TiCl4 for pilot-scale flocculation was found to be equal to 21 g/L DWT (Dye wastewater titania) size was 15-20 nm, mainly doped with carbon atoms and exhibited a dominant anatase structure DWT was similar to P-25 in ....

Properties: Titanium Dioxide

Two main types of titanium dioxide are used industrially, rutile and anatase Due to poor mechaincal properties they are generally used for optical properties as pigments for paints, plastics, ceramic glazes and enamels etc Other uses include oxygen sensors, photovoltaics and antimicrobial coatings...

Application of differential bio

Differential flocculation acts based upon the difference in the settling rates of two minerals So, the application of the bacterial cells, spent medium, extracellular protein, and polysaccharide derived from a cell-free extract of Bacillus licheniformis were investigated to remove hematite and goethite from kaolin and quartz The zeta potentials and settling behaviors of the minerals in the ....
