In the present study, simultaneous gross immobilization of radioactive Cs and Sr in zirconium phosphate was investigated by two methods. “dry method,” a mixture HZr2(PO4)3 with varying amounts CsNO3 Sr(NO3)2 heat-treated at 700 °C for 5 h to prepare + immobilized samples. At 0.3 0.15, leaching 1 mol·dm−3 HCl solution treated 160 24 were 2.9 × 10−4 g·m−2 3.9 g·m−2, respectively. “autoclave aqueo...

This paper discusses the effects of sodium hypophosphite concentration, pH and temperature on deposition rate. This paper also discusses the evaluation of coating strength, surface and subsurface by varying the bath parameters, percentage of phosphate, plating temperature and pH of the plating solution. Taguchi technique has been used for the analysis. In the experiment, Nickel chloride which i...

Enantioselective nickel-catalyzed arylative cyclizations of substrates containing a Z-allylic phosphate tethered to an alkyne are described. These reactions give multisubstituted chiral aza- and carbocycles, and are initiated by the addition of an arylboronic acid to the alkyne, followed by cyclization of the resulting alkenylnickel species onto the allylic phosphate. The reversible E/Z isomeri...

The protection of metallic surface is commonly done with zinc phosphate in acid aqueous phosphate solutions containing zinc ions and phosphoric acid, as well in addition of other metallic ions (nickel, chromium, calcium, niobium etc.), in presence of accelerators as nitrate ions, hydroxylamine sulfate, benzotriazole and others. The present article is a study on the surface structure of zinc pho...

There has been a considerable amount of interest in the ion-exchange properties layered zirconium phosphates. Potential applications remediation nuclear waste have renewed these inorganic materials, due to their high stability under acidic conditions typically found legacy pools. It well documented that substitution metals with different ionic radii into frameworks materials can alter chemical ...
