摘要: Abstract The adsorption of sodium dodecylsulfonate and tetradecylsulfonate on aluminum hydroxide gels at different pH was studied by a) the rest method b) electrophoretic mobility method. These were produced adequate dilution coagulating solutions obtained neutralizing chloride solution (0.1 m ) with hydroxide. Coagulating characterized neutralization ratio r = [NaOH]/ [Al T ]. shapes experimental isotherms are result two-dimensional condensation heterogeneous surfaces. values free energy changes transfer one CH, group from adsorbed condensed layer to depend surface coverage; they vary 1.3 kT 2.0 . nature normal bond between species adsorbing surfaces is mainly electrostatic. specific areas decrease 1200 2 g −1 500 as increases.
