ChemInform Abstract: THE LANGMUIR‐FREUNDLICH EQUATION IN ADSORPTION FROM DILUTE SOLUTIONS ON SOLIDS

Synthesis, characterization, and evaluation of selective molecularly imprinted polymers for the fast determination of synthetic cathinones

“…In general, the Freundlich isotherm model demonstrates that the monolayer single-solute adsorption from dilute solutions on heterogeneous solid surfaces show quasi-Gaussian distribution of adsorption energies. 47,48 Besides, the related parameters of MIPs to 4-MDMC at different temperatures are better than those of NIPs, which also suggest an excellent imprinting effect owing to the presence of a large number of selective binding sites on the MIPs.…”

Preparation of molecularly imprinted polymers for artemisinin based on the surfaces of silica gel

“…That was why MIPs exhibited the better specific adsorption ability, while NIPs contained irregularly arranged sites and showed nonspecific adsorption. Langmuir-Freundlich isotherm describes the monolayer singlesolute adsorption from dilute solutions on heterogeneous solid surfaces showing quasi-Gaussian distribution of adsorption energies (Jaroniec et al, 1983). It was selected to correlate the experimental data of adsorption isotherm of MIPs for artemisinin and its equation is written as follows:…”

Multicomponent dye adsorption onto carbon using a solid diffusion mass-transfer model

“…Other early investigations demonstrated there is no "perfect" isotherm. Some approaches are totally predictive (Butler and Ockrent, 1930;Jain and Snoeyink, 1973; Myers and Prausnitz, 1965; Kidnay and Myers, 1966;Jaroniec et al, 1983).…”

“…Another group of researchers studied surface heterogeneity and energy distribution on the sorbent surface (Jaroniec et al, 1983;Jaroniec, 1982;Rudzinski et al, 1983; Price and Danner, 1987) but again assumed interactive and competitive effects were zero. Rudzinski et al (1973Rudzinski et al ( ,1973 and Oscik et al (1976) made a registry of surface sites incorporating topography and heterogeneity.…”
