The study include synthesis of hybrids nanocompound through a process intercalation of ascorbic acid in Ni/Al -LDHs by direct and indirect ion exchange. Nano layer, which make it has high ability to build up the useful ascorbic acidinter the layers direction on the human body. To limited the side effect of high concentration of ascorbic acidin human body. Characterization of this compound by X-Ray diffraction technique and FT -IR spectrophotometer before and after intercalation formation of nano compound, then cooperation to sure the form hybrid nanocompound and the two and three dimensional image of the above compound in (AFM) for the nano compound. The results showed the release of hybrids to specific liquids in different (Na2CO3, Na2SO4 ) concentration (0.5)M by direct ion exchange method. On the other hand the whole process is subject to model by pseudo-second order rate expression according to Lagregrans equation. It has been studied the percentage of rate release for both anionic (Ascorbic acid) from Ni/Al -LDHs. The results were as follows: High percentage of release in different liquid follows this arrangement: Na2CO3> Na2SO4. The result explains the ratio control release of anion from nanolayerhybrid prepare by indirect ion exchange process more hourly than release anion from nanolayershybridprepared by direct ion exchange.
