【 摘 要 】

A novel organic-inorganic nanocomposite based on carbamate insecticide-zinc layered hydroxide modified with sodium dodecyl sulphate nanocomposite (ZLH-SDS-PRO) was synthesized through ion exchange method of propoxur with commercially available zinc nitrate at various concentrations. The intercalation of propoxur into the interlayer of zinc layered hydroxide modified sodium dodecyl sulphate (ZLH-SDS) was confirmed by PXRD analysis with the basal spacing of the pure phase nanocomposite at 33.1 Å. The propoxur anions suggested to be arranged in a bilayer form between the galleries of zinc layered hydroxide. The intercalation also supported by Fourier transforms infrared spectra (FTIR) that showing the resemblance spectra between the host and the resulting nanocomposite. The elemental analysis estimates the loading of propoxur anion in the nanocomposite to be 88.17 %. The surface area analysis revealed mesoporous-type material properties for both the host and resulting nanocomposite. The thermal study shows a significant improved thermal stability of the propoxur anion compared to its pure form. The effect of intercalation of propoxur on the morphology of the host, ZLH-SDS crystals was investigated by field emission scanning electron microscopy (FESEM).
