Synthesis And Characterization Of Nanocomposite: 2-4-Dichlorophenoxy Acetate-Zinc-Aluminium Hydrotalcitelike Layers
A direct intercalation of 2,4-dichlorophenoxyacetate (2,4-D) into Zn-Al-Iayered double hydroxide (ZAL) was carried out by spontaneous self-assembly technique to produce Zn- AI-2,4-D nanocomposite (ZAD). The aging process was done by conventional and microwave-assisted methods. For both methods, t...

| الملخص: | A direct intercalation of 2,4-dichlorophenoxyacetate (2,4-D) into Zn-Al-Iayered double
hydroxide (ZAL) was carried out by spontaneous self-assembly technique to produce Zn-
AI-2,4-D nanocomposite (ZAD). The aging process was done by conventional and
microwave-assisted methods. For both methods, the results showed that the intercalation
process resulted in the expansion of the interlayer spacing from 10.7 A in ZAL to around
19.0 - 24.6 A in ZAD. Sharp and intense peaks for 003 and 006 reflections indicate wellordered
layered structure which exhibit some common features of layered materials, e.g.
narrow, symmetrical and strong peaks at low 20values and weaker, less symmetric peaks
at higher 20 values. Further characterization of the resulting materials including organicinorganic
content, surface area and porosity, thermal analysis and morphology, were also
carried out. |
