Release study of growth regulator (Indole butyric acid) from Zn/Al- layered double hydroxide

Abstract

This study presents release of growth regulator (Indole butyric acid) from Zn/ Al –layers double hydroxides (LDHS) to different media as carbonate , phosphate and sulfate for different concentrations by using direct ion exchange method . knowing the effect of all media on release rate of anions from layers double hydroxides results were that the highest values of the percentage to be free in different circles were by the following sequenceNa2CO3> Na3PO4> Na2SO4 .The aim of this study to control the release of growth regulator free from between the layers to reduce environmental pollution problems .
