Comparison of adsorption affinity of anionic and cationic polyacrylamides for montmorillonite surface in the presence of chromium(VI) ions - Springer

For determination of anionic polyacrylamide concentration in the solution the reaction of polyacrylamide with hyamine proposed by Crummet and Hummel was applied. It is based on the spectrophotometric measurements of absorbance generated by the PAM reaction with hyamine 1622 ( N -benzyl- N,N -dimethyl-2-{2-[4-(2,4,4-trimethylpentan-2-yl)phenoxy]ethoxy}ethanaminiumchloride).
