Abstract Global concern over lithium (Li) in the environment has significantly increased due to its widespread uses. However, literature review on Li kinetics alkaline soils is scant. Hence, batch experiments were conducted quantify and simulate retention release of sandy clay loam soils. Sorption isotherms fitted using Freundlich Langmuir equations. Second-order two site (SOTS) multi-reaction ...

In the present work, the effect of initial pH of methylene blue solution on the kinetics of dye sorption from synthetic aqueous solution by a natural waste material namely: orange peels, was studied. Kinetic data were measured in batch conditions. Methylene blue uptake was time contact and solution initial pH dependent. Maximum dye sorption was found to occur at initial pH 9. Two simplified kin...

Based on the data of thermogravimetric analysis values oxygen index (3-δ) in manganite La 0.7 Sr 0.3 Mn 0.9 Fe 0.1 O 3-δ composition, obtained by solid-phase reaction technique, have been calculated. The sorption-desorption curves showed that processes release and absorption at p 2 = 10 Pa 400 are not reversible. minima derivative dδ/d t f ( T ) corresponding to maxima extraction rate indicate ...
