摘要：A controlled release formulation for carbamate insecticide, isoprocarb was successfully developed using zinc layered hydroxide modified with sodium dodecyl sulphate (ZLH-SDS) as host material, resulted in the formation of inorganic-organic nanocomposite material with sustained release properties. The controlled release study was found that phosphate solution yielded highest percentage release compared to sulphate and chloride solutions. The release of isoprocarb from its nanocomposite was found to occur in a controlled manner, governed by first order (phosphate solution) and pseudo-second order (sulphate and chloride solutions). The maximum amount of isoprocarb released from the nanocomposite into solutions was found to be 90.1 %, 59.1 % and 54.0 % for phosphate, sulphate, and chloride solutions, respectively. This formulation allow the automatic release of the active agent to the target at a controlled rate and maintain its concentration in the system within the optimum limits over a specified period of time, thereby providing great specificity and persistence without diminishing efficiency.
