Zirconyl chloride octahydrate

In acid medium, fluoride reacts instantaneously with zirconyl-dye lake which is composed of zirconyl chloride octahydrate, ZrOCl2 8 H20, and sodium 2-(parasulfophenylazo)-l,8-dihydroxy-3,6-naphthalene disulfonate (SPADNS), displacing the Zr2+ from the dye lake to form a colorless complex anion, ZrF62 and the dye. As a result, the color of the solution lightens as the concentration of F increases. 

Zirconyl-acid-SPADN reagent is made by combining equal volumes of sodium 2-(parasulfophenylazo)-l,8-dihydroxy-3,6-naphthalene disulfonate (SPADN) with zirconyl-acid reagent. The former is prepared by dissolving 1 g of it in 500 mL distilled water. The latter is made by dissolving 0.14 g zirconyl chloride octahydrate in 50 mL of distilled water followed by addition of 350 mL cone. HC1 and dilution to 500 mL.

More recently, a similar procedure for the preparation of zirconia-coated silica microspheres was employed by Tsurita and Nogami, who coated 3-pm silica spheres with zirconia derived from zirconyl chloride octahydrate. The resulting zirconia-silica spheres were subjected to thermal treatment in order to bring about crystallization and the subsequent development of the porous structure within the material. 

Zirconyl-acid reagent Dissolve 133 mg zirconyl chloride octahydrate Zr0Cl2.8H20, in about 25 ml distilled water. 

There are several forms of metal(IV) phosphates, including amorphous, crystalline, and pellicular. However, here only the preparation of amorphous zirconium phosphate is described. Phosphoric acid (10 % w/w. 162 ml) was added to zirconyl chloride octahydrate (14.4 g in 112 ml of demineralized water), and stirred at room temperature for 4 h. The resulting gel was washed repeatedly with demineralized water (3 x 500 ml) and centrifuged each time.

The use of zirconyl chloride octahydrate (ZrOCl2 8H2O) as an intestinal phosphate binder in place of aluminum compounds has also been reported (Graff and Bumel 1995).
