Extraction of cobalt ions from aqueous solution by microgels for in-situ fabrication of cobalt nanoparticles to degrade toxic dyes: A two fold-environmental application
Muhammad Shahid,Zahoor H. Farooqi,Robina Begum,Muhammad Arif,Muhammad Arif,Ahmad Irfan,Ahmad Irfan,Muhammad Azam +7 more
TL;DR: In this paper, the mechanism of the adsorption process was investigated by pseudo 1st order, pseudo 2nd order and intra-particle diffusion modeling, and in situ reduction of Co2+ ions loaded into the polymer microgel was carried out to get hybrid system for catalytic degradation of 4-nitrophenol, Eosin and Methylene blue.

Modification of multi-walled carbon nanotubes with tannic acid for the adsorption of La, Tb and Lu ions
TL;DR: In this paper, an environmental friendly sorbent was prepared by modifying multi-walled carbon nanotubes with tannic acid, and the adsorption of La(III), Tb (III) and Lu(III) as a function of contact time, initial solution pH, and quantity of adsorbent was studied using a batch technique.

Competitive biosorption of zinc(II) and cobalt(II) in single- and binary-metal systems by aerobic granules.
TL;DR: The kinetic modelling of metal sorption by granules has been carried out using Lagergren equations and regression analysis of pseudo second-order equation gave a higher R(2) value, indicating that chemisorption involving valent forces through the sharing or exchange of electrons between sorbent and sorbate may be the rate limiting step.

Equilibrium, kinetics and thermodynamic studies for sorption of chlorobenzenes on CTMAB modified bentonite and kaolinite.
TL;DR: The sorption of chlorobenzenes by cetyltrimethylammonium bromide modified bentonite and kaolinite was investigated and followed pseudo-second-order kinetics, suggesting that sorption could be described by a distribution process.
