Adsorption of Malachite Green from Aqueous Phase by Tea Stalk Powder: Parameters, Kinetic, Isothermal, and Thermodynamic Studies

BioResources, 2023
Decolorization of malachite green (MG) from the aqueous phase was investigated using tea stalk powder. The adsorption efficiency decreased with the initial MG concentration, ionic strength of the solution, and heavy metal content.

l‐Leucine‐Based Layered Coordination Polymer Supports for Immobilizing Basic Salts to Yield Solid CO2 Adsorbents Resistant to Moisture and Oxidation

Chemistry – A European Journal, EarlyView.
A layered amino acid–based coordination polymer, (Zn(Leu)2), acts as a support that immobilizes diverse basic salts. The resulting solid sorbents remain nondeliquescent under humid, DAC‐relevant feeds while enabling CO2 capture. The interlayer‐immobilized sorbents exhibit high oxidative stability after accelerated oxidative aging, unlike conventional ...

Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...
