Controlled-release of Avermectin from Organically Modified Hydrotalcite-like Compound Nanohybrids

The intercalation of avermectin (AVM)into sodium dodecyl sulfate(SDS)modified hydrotalcite-like com-pounds(HTlc) was carried out using an evaporating solvent enhanced intercalation method to obtain AVM-SDS-HTlc nanohybrids. It was found that the nanohybrids could well control the release of avermectin, showing the nanohybrids are a potential pesticide controlled-release formulation.The release of avermectin from AVM-SDS-HTlc nanohybrids is dependent on the pH.temperature and the presence of electrolyte in release me-dium. Acidic medium and higher temperature and the presence of electrolytes may induce the higher release rate of avermectin. The release process of avermectin from AVM-SDS-HTlc nanohybrids can be described by pseudo-first-order release kinetics, and the activation energy of release is 279 kJ/mol.
