The intercalation of herbicide, 2,4,5- tricholorophenoxybutyrate (TBA), into zincaluminium- layered double hydroxide (ZAL) for the formation of a new nanocomposite ZAT, was accomplished via anion exchange method. Due to the intercalation of TBA with ZAL interlayer domain, basal spacing expanded from 8.9Å in the ZAL to 23.3 Å in the ZAT. The percentage loading of TBA in the ZAT is 45.5 % (w/w). The FTIR spectra of the nanocomposite shows resemblance peaks of the TBA and Zn-Al-layered double hydroxide indicating the inclusion of TBA into the layered double hydroxide. Surface area of the resulting nanocomposite increased from 1.3 to 15.6 m2g-1 with the nitrogen adsorption-desorption of type IV, indicating the mesopore type of material. © (2014) Trans Tech Publications, Switzerland.
