A well-ordered nanohybrid nanocomposite was formed when the concentration of BNOA was 0.08�M and the molar ratio of Zn to Al, R�=�2. Basal spacing of layered double hydroxide containing nitrate ions expanded from 8.9 to 19.5�� in resulting of Zn�Al-BNOA nanocomposite was obtained indicates that beta-naphthoxyacetate was successfully intercalated into interlayer spaces of layered double hydroxide. It was also found out the BET surface area increased from 1.13 to 42.79�m2�g?1 for Zn�Al-LDH and Zn�Al-BNOA nanocomposite, respectively. The BJH average pore diameter of the synthesized nanocomposite is 199�� which shows mesoporous-type of material. CHNS analysis shows the Zn�Al-BNOA nanocomposite material contains 36.2�% (w/w) of BNOA calculated based on the percentage of carbon in the sample. Release of BNOA from the lamella of Zn�Al-BNOA was controlled by the zeroth and first order kinetics at the beginning of the deintercalation process up to 200�min and controlled by pseudo-second order kinetics for the whole process. This study suggests that layered double hydroxide can be used as a carrier for organic acid herbicide controlled release formulation of BNOA. � 2016, Springer Science+Business Media New York.
