Rp-Synthesis and Characterization of Nano hybrid Compounds and Kinetic Controlled Release Study for regulater growth Andole Butyric Acid From .pdf

Soil Pollution by growth regulaters or other pollutants then poured in to ground water is consider as the most important reasons that affects on human health. To control this problem we synthesis nano hybrid compounds through intercalation of  (Indole butyric acid) inside Zinc/Aluminum layers double hydroxide by using direct ion exchange method. Then control the rate release of this anionic in to aqueous solution as carbonate, phosphate and sulphate  for different concentration by using direct ion exchange method . This layers have high ability to anionic exchange prison this anionic among its layers then control rate release in to specific liquids.

They had character  this compounds by X-Ray powder diffraction used Bragg law to measure the : (d) , Fourier Transform Infrared Spectroscopy (FT-IR)  and (SEM) there techenque were proved the nano hybrid formation .

The results showed the release of nano hybrids to specific liquids in diffierent concentration as well as diffierent acid functions by direct ion exchange method. It was found to be contorted by parabolic diffusion at the beginning of the process. On the other hand , the whole process is followed by pseudo-second order rate expression according to Lagregrans equation .

It has been studied the percentage of rate release for anionic              (IBA^– ) from Zinc/Aluminum layers double hydroxide .

The results were as follows :

_ High percentage of release in different liquid follows this arrangement :

Na₂CO₃ > Na₃PO₄ > Na₂SO₄

_ High percentage of release in different concentration to the same  liquid follows this arrangement :

0.600 > 0.060 > 0.006

The effects clarified that the kinetic ion exchange for the number of percentage release to anionic (IBA^– ) from the layers of nano hybrid compound  that synthesis in precent ethanol is being faster than other nano hybrid compound synthesis in precent watery if show nano hybrid compound synthesis in watery parabolic diffuision from other nano hybrid compound synthesis in ethanol and the release time highter  nano hybrid compound synthesis in watery is highter than nano hybrid compound synthesis in ethanol.
