How to study polymer adsorption on basal plane surfaces of kaolin?

It is extremely difficult if not impossible to study polymer adsorption on individual type of basal plane surfaces of kaolin by TOC analysis. A quartz crystal microbalance (QCM-D) is used to study polymer adsorption on silica and alumina as model basal planes of kaolin.

Does kaolin adsorb H-Pam?

Al-PAM and Fe-PAM show similar adsorption characteristics, exhibiting a higher adsorption amount than H-PAM at polymer dosages lower than 25 ppm, which corresponds to a better flocculation performance of kaolin by these two polymers than by H-PAM. At 50 ppm, the amount of H-PAM adsorbed by kaolin is much higher than that of Al-PAM and Fe-PAM.

What is the adsorption rate for Al-Pam & Fe-Pam?

For Al-PAM and Fe-PAM, adsorption measurements were performed at 100 ppm since there was a continuous increase in d50M of kaolin suspension with increasing polymer dosage up to 100 ppm in flocculation studies on oil sands tailings. Thus 100 ppm was chosen for Al-PAM and Fe-PAM.

Is Al-Pam a good solution for kaolin sands tailings?

With the success of Al-PAM for treating fluid fine wastes using thickening and filtration technology, another novel organic–inorganic hybrid polymer, Fe (OH) 3-polyacrylamide (Fe-PAM) was recently synthesized and found to be as effective as Al-PAM in flocculating both kaolin suspensions and laboratory extraction oil sands tailings.
