(2022-08-25)Activated iron media has been proven effective for treating a variety of environmental contaminants with more strengths and less drawbacks comparing to conventional zero-valent iron (ZVI) technology. Despite its success, ...
-
(Texas A&M University. Libraries, 1980)A series of transition-metal-ion forms of phosphates of quadrivalent elements having the general formula X^[IV]M(PO4)2*yH2O(S^[IV] = Zr or Ti; M = Cu(II), Co(II) and Ni(II)) have been characterized. The electronic absorption ...
-
(Texas A&M University. Libraries, 1992)The oxygen-sensitive, nickel and iron-containing enzyme carbon monoxide dehydrogenase (CODH) from clostridium thermoaceticum was purified without any significant loss of the activity present in the crude extract. The careful ...
-
(Texas A&M University. Libraries, 1980)The heats of K^+ - H^+ exchange have been measured calorimetrically on three samples of zirconium phosphate of widely differing crystallinity. The more crystalline exchangers both exhibit exothermic reaction over the full ...
-
(Texas A&M University. Libraries, )520-00The intercalation of ten different amines in ??-Zr (HPO4)2*H2O and the exchange of some transition metal complexes into some of the amine intercalates and other forms of zirconium phosphates has been investigated. ...
-
(Texas A&M University, 2008-10-10)One model system for the investigation of selectivity in inorganic ion exchangers is a group of synthetic analogues of the mineral umbite. Hydrothermally synthesized trisilicates with the general form A2BSi3O9.H2O, where ...
-
(Texas A&M University. Libraries, 1980)[alpha]-Titanium phosphate, Ti(HPO4)2 * H2O, has layered structure isomorphous with [alpha]-zirconium phosphate, Zr(HPO4)2 * H2O. Thus, solid solutions of the two compounds were prepared and their properties correlated ...

-
(Texas A&M University. Libraries, 1984)Luminescence probe studies were used to obtain information about the morphology and chemical properties of ion-containing polymers (ionomers). Studies were conducted in polyelectrolyte solutions and solid state ionomer ...
-
(Texas A&M University. Libraries, 1987)Ion-exchange membranes have found many uses for their special separation capabilities and are used currently in electrolysis and fuel cells, batteries, and chemical separations. Bilayer membranes have been particularly ...
-
(Texas A&M University. Libraries, 1981)The exchange of transition metal complexes {Co(NH(,3))(,6)}('3+), {Cu(NH(,3))(,4)}('2+) and {Cu(en)(,2)}('2+) between the layers of (alpha)-zirconium phosphate using butylamine intercalates has been investigated. The ...
-
(Texas A&M University. Libraries, 1982)The catalytic activity of metallic silver supported on zirconium phosphate has been examined in the reaction of ethylene oxidation in a flow reactor. The catalysts were prepared by ion-exchange of silver(I) ions in ...
