Staff View: Hybridisation of chlorophenoxyherbicides with layered double hydroxide for the formation of layered organic-inorganic encapsulated agrochemical nanocomposites.

Hybridisation of chlorophenoxyherbicides with layered double hydroxide for the formation of layered organic-inorganic encapsulated agrochemical nanocomposites.

Agrochemicals of phenoxyherbicides-type, namely 2-chlorophenoxyacetate (2CPA) and 2,4,5 trichlorophenoxyacetate (TCPA) were encapsulated separately into zinc-aluminium-layered double hydroxide inorganic interlamellae for the formation of new organic-inorganic hybrid nanocomposites materials, N2CPA a...
