On Kinetics of Phage Adsorption [PDF]
Biophysical Journal, 2007 Adsorption of lambda-phage on sensitive bacteria Escherichia coli is a classical problem but not all issues have been resolved. One of the outstanding problems is the rate of adsorption, which in some cases appears to exceed the theoretical limit imposed by the law of random diffusion.

FABRICATION OF Mg-Zn-Al HYDROTALCITE AND ITS APPLICATION FOR Pb2+ REMOVAL
Acta Polytechnica, 2019 The fabrication of Mg-Zn-Al Hydrotalcite (HT) was carried out by the co-precipitation method at various molar ratios. The Mg-Zn-Al HT compound at the optimum molar ratio was then calcined to determine the effect of calcination on the Pb2+ adsorption. The

Surfactant adsorption kinetics in microfluidics [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance Surfactant adsorption to interfaces is a dynamic process of relevance for foaming, emulsification, and detergency. Although the process has been described for centuries now, the rational measurement of adsorption and desorption constants, as well as the modeling of the binding mechanism, is still subject to many assumptions.

Implications of apparent pseudo-second-order adsorption kinetics onto cellulosic materials: A review
BioResources, 2019 The pseudo-second-order (PSO) kinetic model has become among the most popular ways to fit rate data for adsorption of metal ions, dyes, and other compounds from aqueous solution onto cellulose-based materials.
