“…The carboxylation reaction by oxygen is disregarded for some reasons: (1) low reaction temperature (À5-0°C) in the absence of air (oxygen), (2) no color change due to oxidation, (3) absence of characteristic asymmetric and symmetric carbonyl stretching bands (both strong at 1600 and 1430 cm À1 , respectively). 17 As for carbonation, some FTIR analyses have been reported related to the characteristic peaks of the carbonate ion. The characteristic peaks at 1673, 1350, and 1305 cm À1 are reported for sodium hydrogencarbonate ion.…”

“…It is worth to remark that CMC used in this work was as sodium salt. The assignments are according with reports of IR spectroscopy studies of CMC (Bono et al 2009, Heydarzadeh et al 2009, Vasile et al 2004. Before, the main assignments for PHEMA were disscused.…”
