Abstract: The study present the synthesis nano compound through a process intercalation of insecticide (chlorpyrifos) in Mg/Fe-LDHs by indirect ion exchange. Characterization of this compound (chlorpyrifos, Mg/Fe-LDHs and nano compound) done by DXR technique and FT-IR spectrophotometer before and after intercalation formation of nano compound, then cooperation to sure the form nano hybrid organic-inorganic compound and the two and three dimensional image of the above compound in Atomic Force Microscope (AFM) for the layer and nano compound. The aim of this study, is the synthesis hybridnano compounds can be controlled release insecticide (Chlorpyrifos) by ion exchange process for limited of environment pollution. The results appeared the release of hybrids to specific liquids in different (Na2CO3, Na2PO4) concentration (0.5 m) by direct and indirect ion exchange method. It was found to be contorted by parabolic diffusion at the opening of the process then again the whole process is governed by pseudo-second order rate appearance according to Lagregrans equation addition the studied percentage of rate release for both anionic (Chlorpyrifos) from Mg/Fe-LDHs The results high percentage of release in different liquid follows this arrangement: Na2CO3Na2PO4.
