1.Reagents:The chemicals used in this work were,ammonium molybdate,diammonium monohy-drogen phosphate,ascorbic acid,ammonium metavanadate,.zine powder and sodium hydroxide,etc.
All of these reagents were analytical grade and doubly distilled water was used.
2.Apparatus A Model pH s_2 meter (Shanghai Second Analytical Instruments Factory) was used to measure the pH of the solution.Absorption spectra and absorbances were recorded and measured on
a Model WFZ800-D3A spectrophotometer (Beijing Second Optical Instruments Factory).The X-ray diffraction spectrum were measured with a Model TURM6z X-ray spectrometer (Germany).
