| description | Layered double hydroxide or hydrotalcite-like compound is a material that can be used to as a support for controlled release formulation and become an ideal solution to solve environmental problem arise from agrochemical. In this study, synthesis of CaAl-3, 4 Dichlorophenoxyacetic acid was successfully attained by the coprecipitation method with the molar ration of Ca to Al; R=2 at different concentration of 3,4-Dichlorophenoxyacetic acid. The pH for synthesis this nanocomposites is 13 ± 0.05 and kept in constant. The result obtained from the PXRD spectra showed that the basal spacing for the nanocomposite was increased from 8. 7 6 A to 15 .4 7 A. Other than that, FTIR spectrum of the synthesis of CaAl- 3, 4-D nanocomposite showed the similarities of CaAl-LDH and the pure 3,4-D absorption bands which confirm the 3,4-D inserted into LDH interlayer. Besides that, there were also disappearance of the nitrate peak and formation of new peak which indicates the C=O stretching. For controlled release study, 3,4-D more efficient release in aqueous solution of Na2CO3 compare to NaCl with percentage release is 20.65%. |
