An Ft-ir Study of Calcium-exchanged Montmorillonite Treated With Polyacrlamide and Polyethylene Oxide.
Miner and Metall of Proc 1990 Nov; 7(4):206-208
The U.S. Bureau of Mines is using fourier-transform infrared (ft-ir) analysis to investigate the bonding mechanism that occurs during the dewatering of clay slurries. High-molecular-weight polymers are used as flocculating agents in these processes. This investigation presents the results of an ft-ir study of calcium-exchanged montmorillonite treated with polyacrylamide (pam) and polyethylene oxide (peo). Both thin film and attenuated total reflectance (atr) spectroscopic techniques were employed to study this clay-polymer system. Results suggest pam is adsorbed to the clay via the nitrogen atom of the polymer. A water bridge is involved in the bonding between the clay and peo. Evidence also suggests that peo may be adsorbed directly onto the surface of the clay.
