Assessment of Novel Synthetized Nanozirconium Tungstovanadate as Cation Exchanger for Lead Ion Decontamination

Table 7

Details of IR spectrum of nano-zirconium tungstovanadate.

Wave number (cm^−1)	Significance
3000–3500	Hydroxostretcing vibrations (–OH groups)
1600–1630	Deformation vibrations of coordinated water (H–O–H bonding)
1400–1420	Vibrations due to metal hydroxyl groups (M–OH)
600–750	Superposition of metal oxygen stretching vibrations (W–O, Zr–O, V–O).
