Fractal-Like Kinetics Study of Adsorption on Multi-walled Carbon Nanotube

Authors

Abstract:

The fractal degree of adsorption on the multi-walled carbon nanotube has been investigated. The fractal-like Langmuir kinetics model has been used to obtain the fractal degree of ion adsorption on multi-walled carbon nanotube. The behavior of the fractal-like kinetics equation was compared with some famous rate equations like Langmuir, pseudo-first-order and pseudo-second-order equations. It is shown that the kinetic of adsorption onto multi-walled carbon nanotube can be used to obtain its spectral dimension, successfully.

Multi-Fractal Hierarchy of Single-Walled Carbon Nanotube Hydrophobic Coatings

A hierarchical structure is an assembly with a multi-scale morphology and with a large and accessible surface area. Recent advances in nanomaterial science have made increasingly possible the design of hierarchical surfaces with specific and tunable properties. Here, we report the fractal analysis of hierarchical single-walled carbon nanotube (SWCNT) films realized by a simple, rapid, reproduci...

Modeling of the adsorption kinetics of Basic Red 46 on single-walled carbon nanotube and carboxylate group functionalized single-walled carbon nanotube

The present study was carried out to investigate the potential of single-walled carbon nanotube (SWCNTs) and carboxylate group functionalized single-walled carbon nanotube (SWCNT-COOH) as alternative adsorbents for the removal of Basic Red 46 (BR 46) from contaminated water by using batch adsorption studies. Effects of some key operating parameters such as pH, ionic strength and contact time on...
