Smectite-polymer composites from cationic polyacrylamide (PAM S,τ40 Cl) were prepared to investigate the adsorption behavior of the smectite after the intercalation procedure. PAM S,τ40 Cl solutions with two different concentrations (γ = 5.18 g/L corresponds to 4.3 mmol/L and γ = 3 g/L corresponds to 4.3 mmol/L) were used to manufacture smectite-PAM + S,τ40 composites.
Adsorption of Polyacrylamide on Smectite, Illite,
Interactions between polyacrylamides (PAMs) and clay minerals are the primary reactions in most applications of the water‐soluble polymers. Our main objectives were to study (i) the effects of charge...
Deng et al. [33] studied the adsorption of anionic, non-ionic and cationic polyacrylamides on smectite clay as a function of pH and polyacrylamide concentration. The amido groups on nonionic
Bonding between polyacrylamide and smectite - ScienceDirect
A smectite clay (<2 μm) was separated from a Texas bentonite (Southern Clay Products Inc., Gonzales, Texas) by centrifugation and saturated with Ca 2+.The smectite had a cation-exchange capacity of 81.2 cmol(c) kg −1 and a total surface area of 787 m 2 g −1.Three polyacrylamides were used: nonionic PAM 903N, cationic PAM 494C containing 20% cationic N,N,N-trimethyl-aminoethyl acrylate
The adsorption and readsorption isotherms are similar until c* p, while the adsorption is much higher than readsorption for concentrations higher than c* p. Therefore, if the polymer concentration of the mobility control bank is greater than c* p , the total polymer loss during field applications can be reduced by preinjecting a polymer bank of ...
Sustainable post-industrial land restoration and re
There are five commercially available polyacrylamide (PAM) gels on the market which could be suitable for aiding the restoration of land which is limited by water and nutrients. The gels have different formulations which make some more suitable to the Welsh or Irish climates and others to the Spanish site.
