The decrease in the equilibrium sorption of Pb(II) and nonionic surfactants (oxyethylated alcohols OS-20 and alkylmonoethers ALM-10) in H-form of Purolite C 106 cation exchanger was observed due to their presence in the same solution. The sorption of Pb(II) both in the form of free cations and in the form of Pb(II) bonded with surfactant takes place. The sorption of Pb(II) bonded with OS-20 is higher compared with that of Pb(II) bonded with ALM-10. In the presence of ALM-10 the sorption of Pb(II) free cations prevails. Increasing the acidity from pH 5 to pH 3, increases the rate of the sorption of surfactant. Due to the presence of surfactant the rate of Pb(II) sorption also increases, while without surfactant it decreases with an increase in acidity.
