Ftir Analysis Of Adsorption Of Poly Diallyldimethyl

Jun 01, 2008 When macromolecule polymer is adsorbed on surface, kaolinite particles may be flocculant due to the bridging effect. There are cation flocculant characteristic bands on the spectrum of kaolinite but no obvious shifting. Thus, the adsorption of poly diallyl-dimethyl-ammonium chloride on kaolinite surface is physical adsorption.
