Preparation of MOEAMCl and MAAm Based Hydrogels and Effective Use in Anionic Dye Adsorption

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 16, April 20, 2025.
ABSTRACT In this study, hydrogels based on [2‐(Methacryloyloxy)ethyl]trimethylammonium chloride (MOEAMCl) and methacrylamide (MAAm) were synthesized for the removal of anionic dyes from aqueous solutions. Following detailed characterization, the use of hydrogels for methyl orange (MO) adsorption was investigated.

A comment on the derivation of the Langmuir isotherm for the adsorption kinetics [PDF]

open access: yes, 1991
The justification for the use of the Langmuir isotherm, basically an equilibrium relation, to relate the subsurface concentration C(t) at time t to the adsorbed surface concentration T(t) depends, in many adsorption kinetics models, on the presence of ...

Composition‐Tunable Lignocellulosic Aerogels From Eucalyptus spp. Bark for Oil and Cu2+ Adsorption

open access: yesJournal of Applied Polymer Science, EarlyView.
Composition‐tunable lignocellulosic aerogels are produced from Eucalyptus spp. bark by combining cellulose, lignin, and microfibrillated cellulose without post‐synthetic functionalization. The resulting porous architectures show contaminant‐dependent performance: CEL favors cooking‐oil uptake, CEL‐M favors pump‐oil uptake, and CEL‐L‐M provides the ...

Calixarene-based langmuir monolayers : from crystallization templates to metal organic networks [PDF]

open access: yes, 2015
Molecular self-assembly plays a pivotal role in biological processes and living organisms can be considered as the result of the self-assembly of discrete molecular building blocks into sophisticated functional structures.

Characterization of Molecularly Imprinted Polymers with the Langmuir−Freundlich Isotherm

open access: yes, 2016
The majority of binding models that have been applied to molecularly imprinted polymers (MIPs) have been homogeneous models. MIPs, on the other hand, are heterogeneous materials containing binding sites with a wide array of binding affinities and ...
