Synthesis of a layered organic-inorganic nanohybrid of 4- chlorophenoxyacetate-zinc-layered hydroxide with sustained release properties
A zinc-layered hydroxide-4-chlorophenoxy acetate (4CPA) organic-inorganic nanohybrid was prepared using a simple direct reaction of 4CPA anions with ZnO under an aqueous environment to be used as a controlled release formulation of the herbicide, 4CPA. The concentration of the active agent, 4CPA, wa...
