Surfactant-induced adsorption of Pb(II) on the cracked structure of microplastics.

Journal of Colloid and Interface Science, 2022
Surfactant molecules can change the hydrophobic nature of microplastic surfaces, thereby affecting the adsorption of heavy metals in the environment onto the microplastics.

Surfactant adsorption dynamics

International Reviews in Physical Chemistry, 2001
Advances in techniques for investigating dynamic adsorption of surfactants at the air-water interface are discussed. Of particular interest are the maximumbubble-pressure method, and the interrogation of adsorption layers on an overflowing cylinder (OFC) cell using ellipsometry, surface-light scattering, laser Doppler velocimetry and neutron reflection.

Surfactant adsorption dynamics

Journal of Colloid and Interface Science, 1982
Abstract The rates of adsorption of surfactants on solid surfaces were investigated in a packed bed apparatus. Using a nonequilibrium linear isotherm, adsorption and desorption coefficients were obtained by fitting observed peaks from slug input experiments.

Electrokinetic investigation of surfactant adsorption

Journal of Colloid and Interface Science, 2007
Fuerstenau [D.W. Fuerstenau, in: M.L. Hair (Ed.), Dekker, New York, 1971, p. 143] has already discussed the role of hydrocarbon chain of surfactants, the effect of alkyl chain length, chain structure and the pH of the solution on the adsorption process of surfactants. Later Kosmulski [M.
