  • What is the adsorption capacity of cationic polyacrylamide (PAM)?
  • The adsorption of cationic polyacrylamide (PAM) increases with pH from 5.50 to 11.00, temperature from 25 to 55 °C and ionic strength from 0 to 0.1 mol L −1. The sepiolite sample calcined at 200 °C has a higher adsorption capacity than the other calcined samples.
  • What factors affect adsorption of Pam onto sepiolite from aqueous solutions?
  • The adsorption of PAM onto sepiolite from aqueous solutions has been investigated systematically as a function of some parameters such as calcination temperature of sepiolite, pH, ionic strength and temperature.
  • What is the nature of ammonium ion adsorption by sepiolite?
  • Nature of ammonium ion adsorption by sepiolite: analysis of equilibrium data with several isotherms Properties and applications of palygorskite-sepiolite clays Adsorption of polyelectrolytes onto oxides-the influence of ionic strength, molar mass, and Ca 2+ ions Colloid. Surf.
  • Does sepiolite have a positive zeta potential?
  • Sepiolite is slightly negatively charged in this pH range, the adsorption of a large amount of positively charged PAM onto the surface of sepiolite gives rise to a reversal in zeta potential. As more positively charged PAM is attached onto the particle surface, the zeta potential becomes more positive.
