Recently, I have done an experiment. In this work, the Al and Zr salt mixtures has refluxed in presence of dilute nitric acid medium with cellulose for 72h. when we analysed cellulose material using XRD spectrum, there is a new peak observed at 2theta = 6.5 degree with high intensity. What reflects in this sharp XRD peak at 6.5. Is there any possibilty to get Zirconium aluminium oxide [Zr5Al3]O0.5 loaded onto cellulose polymer. Could anyone calrify me what kind of metal (Zr and Al) complex can formed onto cellulose polymer and what kind of explain we can give reason for the formation of this XRD (2theta = 6.5 degree)?
provide more: sample details, instrument setting and diffractogram (SRM and sample), or maybe elemental analysis.
Dear Barathi,
When calculated by using the Bragg's law for 2theta=6,5°, the interlayer distance found around 13-15 A°. This is an interlayer distance which is relatively long. May be you can search in a database including the elements of Zr, Al and oxygen.
as i know cellulose has two peaks at 15.4 and 22.6 2theta you must post drx spectra for more exploration.
Thanks for all to post your comments.
I have checked database, some peaks are related to Al and Zr oxides.But i could not come to know the peak shows at 6.5 degree in XRD spectrum. XRD peaks related to cellulose is observed in this XRD Spectrum.
Still i am stuggling to indentify the peak shows at 6.5 degree.
Anyhow, thanks for all your suggestions.
Can you share your soft pattern so that I can have a look and to have possible reasoning for it.,..
as i see your rx pattern you have both C12H13NO4 and Al3Zr2, the compound C12H13NO4 have peaks :
No. h k l d [A] 2Theta[deg] I [%]
1 13,16000 6,711 100,0
2 9,73000 9,081 5,0
3 5,24000 16,907 80,0
4 4,43000 20,027 100,0
d-spacing about 13.16 A° , perhaps good luck for searching
Thank you so much Khalid Dakshi.
I would be grateful if provide me those compounds PDF file no.
The peak shows at 6.5 degree only i could not get it till now..Could you help me to find out that peak..
Once again thank you so much for your valuable comments.
It seems to me some artefact in one of the pattern apear as a peak at lower angle. But may not be a peak stemming from your sample..
please this is the refrence number for compounds : 00-046-1896 as C12H13NO4 and 03-065-6868 as Al3Zr2. but you shood have a repetitive DRX analysis that corespond at peak B.
otherwise as Mr Bhange D.S. say it is necessary that this result is generated several times for the same series of samples
Thanks a lot to Bhange DS and Khalid Dakhsi for your support and valuable suggestions.
