Adsorption Kinetic of Malachite Green Dye from Aqueous Solutions by Electrospun Nanofiber Mat

Abstract

A resin of 2-aminophenol-formaldehyde (2-A-Ph-F) was prepared and characterized by FT-IR technique. This resin was loaded on polystyrene (PS) as a matrices using DMF solvent, after that the polymer solution was used in electrospinning process in order to result electrospun nanofiber mat (2-A-Ph-F)/PS which has been used as adsorbent surface for studying the adsorption kinetic of malachite green dye (MG) at different temperatures to observe the behavior of this adsorption system. Generally, there is an increase in the values of rate constants with increasing temperature and the experimental results obeyed very well Lagergren's equation. So, the activation energy value (Ea) was estimated by Arrhenius equation, while the diffusion mechanism and the rate controlling steps explained according to Weber's intraparticle diffusion model.

“…In recent years, nanofiber technology has been one of the most important research topics in the field of pollutant removal [18] . This is due to the fact that electrospun nanofiber membranes are excellent adsorbent materials because of their high surface area, porous structure and strong mechanical properties [19][20] .…”

Adsorption behavior of Crys tal Violet dye in aqueous solution using Co+2 hectorite composite as adsorbent surface

“…The adsorption capability of some reactive dyes by activated carbon is known to be relatively poor. The sewage treatment process utilizing clay-basic [21], AC-ZnO nanos tructure [22], cotton [23], Ultraviolet-activated sodium perborate [24], halloysite nanotubes [25], electrospun nanofiber mat [26], chitosan [27], and natural zeolite-basic [18] has thus been the subject of Previous s tudies. Because of their large surface area and molecular sieve composition, Clay-based materials are efficient organic cation pollutant adsorbents [3].…”
