| Abstract: | The interaction for Gelatin with Silver(I) ion have been developmented by UV/Vis, IR spectra, TEM and conductance.electropheresis methods respectively. Where were also investigated that the effect of pHmedium, temperature and multicomponent concentration on interaction gelatin-silver. It is an autocatalysis reduction process that reaction of gelatin-silver, and a colloid system on any condition. It has maximum absorbance at 233 and 422nm. It is formed a multinucleate complex under suitable condition first, then reduced to metalic Ag particle and collectived to superfine colloidal gel, which is carried on positive charge, diameter of colloid particle about is 30nm and electrokinetic potential of double electrode layer is 0.014~0.016V. |
