Photocatalytic degradation of ciprofloxacin by synthesized TiO2 nanoparticles on montmorillonite: Effect of operation parameters and artificial neural network modeling
TL;DR: In this paper, the average size of TiO 2 nanoparticles was decreased from 60-80nm to 40-60nm through the immobilization on MMT and the predicted data from the designed artificial neural network model were found to be in a good agreement with the experimental data ( R 2 ǫ = 0.9864).

FTIR techniques in clay mineral studies
TL;DR: In this paper, the authors used FTIR techniques to distinguish between different types of clay minerals and to derive information concerning their structure, composition and structural changes upon chemical modification, and the selection of the sampling technique used depended on the purpose of the study and on the physical state of the sample.

The adsorption kinetics of the cationic dye, methylene blue, onto clay.
TL;DR: It was found that the pseudo-second-order mechanism is predominant and the overall rate of the dye adsorption process appears to be controlled by the more than one-step.

Equilibrium and kinetics studies of adsorption of copper (II) on chitosan and chitosan/PVA beads.
TL;DR: Results showed that chitosan and chitOSan/PVA beads are favourable adsorbers and properly correlated with the second-order kinetic model, which indicates that the chemical sorption is the rate-limiting step.
