The intercalation of herbicide, 3,4-dicholorophenoxyacetic acid (3,4D), into zincaluminium- layered double hydroxide (LDH) for the formation of a new nanocomposite Zinc- Aluminium-3,4D (ZADX), was accomplished via anion exchange method. Due to the intercalation of 3,4D with LDH interlayer domain, basal spacing expanded from 8.9Å in the ZAL to 17.7-19.0 Å in the ZADX. The percentage loading of 3,4D in the ZADX is 51.4% (w/w). The FTIR spectra of the nanocomposite shows resemblance peaks of the 3,4D and Zn-Al-layered double hydroxide indicating the inclusion of 3,4D into the layered double hydroxide. Surface area of the resulting nanocomposite increased from 1.3 to 7.14 m2g-1with the nitrogen adsorption-desorption of type IV. © 2016 Trans Tech Publications, Switzerland.
