Abstract:In this study ferric oxide sols solutions were prepared in presence of different electrolyte and their zeta potentials were measured by simplified electrophoreses method with protective semi membrane filters. The stability of these sols solution was affected by particles size and electrolyte pH.

Such pectin (5.77±0.02)%, fiber (24±0.01)%, lignine (10.790.03)% have been founded in the medicinal herb called ‘Angelica’. The average molecule mass of pholysugar was determined by the methodology of chromatography of chromatography of gel-filtration of the (15500-400000). It has founded first time that the glucose thermal galactose has connected as 1,4 connection in connection with the monomer assortment of neutral pholysugar founded in monosaccharide. The rhamnose-terminal, xylose-terminal are connected by 1,3 connection in the circulation of macromolecule of polysaccharide. Pectin of substance derivative compound to extract. In polysaccharide has to establish etherify carboxyl group (7.47)% and methoxyl group (5.14)% and etherification degree (51.4)%.
