A review of a certain class of theoretical models describing the kinetics of pollutants sorption
onto various sorbents is presented. These assuming the rate of surface reaction as the rate …

The kinetics of adsorption for Langmuir and Freundlich isotherms has been explored
theoretically on the basis of Statistical Rate Theory (SRT). The Modified Pseudo-First-Order …

The past decade has seen a boom in environmental adsorption studies on the adsorptive
removal of pollutants from the aqueous phase. A large majority of works treat kinetic …

One of the first reported equations to describe adsorption at equilibrium is the Langmuir
model (J. Am. Chem. Soc. 1918, 40, 1361–1403). Initially, the model was used to describe …

In this work, a grafted (with carboxylic groups) chitosan material was synthesized and the
adsorption mechanism of a basic dye (Remarcyl Red TGL denoted as CR) and a heavy …

Adsorption is an important phenomenon, underlying a number of processes of great
environmental and technological significance. The vital role of adsorption in industry and …

Two novel chitosan (CS) adsorbents were prepared in powder form, after modification with
the grafting of itaconic acid (CS-g-IA) and cross-linking with either glutaraldehyde (CS-g-IA …

Natural zeolite as a low cost clay was tested for removal of crystal violet known as a noxious
dye. Five characterization techniques were used for this study Optimizing and modeling of …

The kinetics of adsorption processes at the solid/solution interface has been studied by
using a fractal-like concept. For the first time, one possible physical meaning for fractal-like …

The pseudo first-(PFO) and second-order (PSO) kinetic models have been extensively
applied to study the kinetics of interfacial processes, for example, separation or removal of …
