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

Journal 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.

Sustainable and Efficient Removal of Organic Dyes From Water Using a Graphene Oxide‐Conjugated PEGylated Polystyrene Resin

Journal of Applied Polymer Science, EarlyView.
A graphene oxide‐functionalized PEGylated polystyrene (PS‐PEG@GO) resin is developed as a recoverable, reusable adsorbent for cationic dye removal from water. Combining efficient multi‐dye adsorption with simple filtration‐based recovery and stable reuse, it retains over 90% removal for CV and MB and 89.19% and 85.15% for R6G and RB after 20 cycles ...

Adsorption mechanisms of pigments and free fatty acids in the discoloration of shea butter and palm oil by an acid-activated Cameroonian smectite

Scientific African, 2020
Discoloration mechanism of shea butter and palm oil was studied by the adsorption of pigments and free fatty acids onto a Cameroonian clay. Adsorbent characterization was performed using ICP-AES, FTIR, SEM, N2 gas adsorption and CEC.

Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.

Tipos de participación política y bienestar subjetivo: Un estudio mundial

Estudios Sociológicos, 2017
El bienestar subjetivo ha sido descrito como, tal vez, “la variable dependiente fundamental” de las ciencias sociales, por lo cual no resulta sorpresivo que una buena parte de la literatura empírica sobre el tema se ha enfocado en identificar sus ...

Remediation of Organic Pollutant for Wastewater Treatment by Employing Sustainable Graphene Oxide/NiO‐ZrO2/Zeolite Ternary Composite Material

CleanMat, EarlyView.
Graphene oxide/NiO‐ZrO2/zeolite ternary composite was synthesized hydrothermally. Efficient adsorption of Congo red onto GO/NiO‐ZrO2/zeolite composite was studied. ABSTRACT The present study employs a novel method for the synthesis of graphene oxide (GO) based ternary composite utilized for the adsorption of Congo red (CR), an anionic dye molecule. The
