The flocculation of coal (anthracite) suspension by a high molecular weight polyethylene oxide (PEO) has been studied and the results correlated with the adsorption of PEO at the coal/water interface. The effects of pH, inorganic salts, H-bonding agents, methylation and oxidation on the adsorption and flocculation behaviour have been determined. The mechanism of polymer adsorption would appear to be through hydrophobic interactions between the -CH2- groups in the polymer molecule and the coal surface. However, the small decrease in polymer adsorption obtained in the presence of H-bonding competitors suggests that H-bonding may have a minor role in the adsorption process. |
