Modeling the sorption kinetic of metsulfuron-methyl on Andisols and Ultisols volcanic ash-derived soils: Kinetics parameters and solute transport mechanisms

Biosorption Potential of the Microchlorophyte Chlorella vulgaris for Some Pesticides

“…The bioremoval of these pesticides over a period of 60 minutes suggested that the probable mechanism as biosorption according to the finds of Komárek, whereas, in Long-term study, there was sufficient time for some mentalizations processes occurred and the algae may either have biosorbed, metabolized or facilitated the degradation of pesticides, or it can be attributed to a combination of all these mechanisms [22]. Exhaustive agricultural activates which depends on using agrochemicals as fertilizers and pesticides, also they increase the global food production but also the at the same time contaminate the environment extensively as suggested by Cáceres, Singh and Walker [23,24].…”

Effect of cations in the background electrolyte on the adsorption kinetics of copper and cadmium and the isoelectric point of imogolite

“…12. (12) where k int (mg·g -1 ·min -1/2 ) is the intraparticle diffusion constant and C is a constant related to the thickness of the surface layer [51,52]. The higher the value of C, the greater the boundary layer effect, which is related to intraparticle diffusivity.…”

Synthesis and evaluation of different adsorbents based on poly(methacrylic acid–trimethylolpropane trimethacrylate) and poly(vinylimidazole–trimethylolpropane trimethacrylate) for the adsorption of tebuthiuron from aqueous medium

“…In addition to this feature, this model also recognizes an adsorption process of chemical nature [39]. As shown in Table 3, Elovich model provides a reasonable fit for PVI and PMA due to reasonable regression coefficients between Qt and ln t (R 2 = 0.9599 and R 2 = 0.8959).…”
