✦ Synopsis

Investigation has been carried out on the kinetic dependences of the adsorption process of aliphatic amidpolyamine (lamide-1, L-1) on three kinds of bleached pulp (sulfate pulp of hard wood and sulfate and sulfite pulp of soft wood) a t temperatures of 0,20,40, and 6OoC within a concentration interval of 0.030 g/liter + 0.500 g/liter. It has been established that the kinetic process can be described by the Elovich-Tyomkin exponential kinetic equation. The activation energy is of the order of 4.12-4.42 kJ/mol and the entropy factors substantially affect the process speed. The coefficients of the correlations describing the effect of the L-1 solution concentrations on the coefficient of heterogeneity ( a ) and the initial adsorption speed ( V,) have been determined.
