Modification of Nano-Titanium Dioxide Film and Processing Experimental Study of Tannery Waste Water
Modification Nano Meter Titanium Dioxide Photocatalysis Tannery Wastewater
2011/12/16
This paper was prepared by liquid phase deposition of quartz sand load nanometer titanium dioxide film, in which quartz sand as the carrier, and to Fe3+,Zn2+ as doping on the membrane was modified. Th...
Extraction of Iron Oxides from Sediments Using Reductive Dissolution by Titanium(III)
Dissolution Dithionite Extraction Goethite Hematite Reduction Titanium(III)
2012/1/4
A new iron oxide dissolution method designed to measure the abundance of “free” Fe oxide phases and associated elements in soils and sediments has been tested. The method employs a ternary complex of ...
Synthesis and Properties of Titanium Oxide Cross-Linked Montmorillonite
Cross-linked smectite Montmorillonite Pillared interlayer complex Porosity Thermal stability Titanium oxide
2012/1/13
Titanium was introduced into the montmorillonite structure by cation exchange with polymeric Ti cations, formed by partial hydrolysis of TiCl4 in HCl. On further hydrolysis and heating, TiO2 pillars i...
Amorphous and Crystalline Titanium and Iron-Titanium Oxides in Synthetic Preparations, at near Ambient Conditions, and in Soil Clays
Anatase Goethite Hematite Iron Pseudorutile Synthesis Titanium
2012/2/10
A series of mixed iron and titanium oxide coprecipitates ranging in composition between 0 < Ti/Ti + Fe < 1 was synthesized and aged under varying conditions of pH, temperature and time in order to est...
Vanadium-Titanium-Bearing Mixed-Layered Clay from Potash Sulphur Springs, Arkansas
Mixed-layer Titanium Vanadium
2012/2/10
A unique vanadium-titanium-bearing mixed-layered clay is currently being mined as an ore of vanadium at Potash Sulphur Springs, AR. The clay contains 80% expandable portion and has both a 14.22 and 18...
Titanium as Free Oxide and Substituted Forms in Kaolinites and Other Soil Minerals
Titanium Free Oxide Substituted Forms Kaolinites Soil Minerals
2012/2/20
Titanium in TiO2 minerals was differentiated from that isomorphously substituted into minerals by the use of dihydrogen hexafluorotitanate (hydrofluotitanic acid, H2TiF6), which selectively dissolved ...
A Method for Removing Titanium Dioxide Impurities from Kaolin
Removing Titanium Dioxide Impurities Kaolin
2012/2/20
The removal of titanium minerals from kaolin can be accomplished by treatment with dispersing agents in an amount in excess of that required to produce maximum deflocculation of the kaolinite particle...
