Summary: The use of new synthetised materials as adsorbents for wastewater disposal is important, and the Hydrotalcite-like compound Mg-Al-CO3 (HT2) shows high adsorption capacity for malachite green (MG). All factors, including MG concentration, pH, and contact time, influence the adsorption process. The second-order kinetic model and Langmuir isotherm model are suitable for describing the adsorption behavior, and the adsorption of MG dye on Hydrotalcite is a spontaneous and endothermic physical process according to thermodynamic studies.

Summary: The performance of a nanocomposite adsorbent, comprised of nickel ferrite, zinc oxide, and alpha alumina nanoparticles on a graphene oxide substrate, was investigated for the removal of malachite green. The composites were characterized using various spectroscopy and imaging techniques, confirming the presence of particles and preservation of particle structure in COM4. The adsorption efficiency was examined under various conditions, showing maximum adsorption using the Langmuir model at pH 7 and ambient temperature. The adsorption mechanism was proposed to involve surface functional groups, electrostatic interactions, H-bonding, 7C-7C interactions, and permeation of dye molecules into the pores of the adsorbent. The adsorbent exhibited good performance for multiple cycles after washing with ethanol.

Summary: The decolorization of malachite green (MG) from the aqueous phase was examined using tea stalk powder. The adsorption efficiency decreased with the initial MG concentration, ionic strength of the solution, and heavy metal content. A suitable initial MG concentration of up to 200 mg/L can be accepted since adsorption efficiency of more than 95% is achieved. Different adsorption kinetic models were employed to fit the experimental data, and the pseudo second-order model provided the best fit. The calculated adsorption capacities using the pseudo second-order model were close to the experimental data for different initial MG concentrations ranging from 24.27 to 158.7 mg/g. The Langmuir isotherm fit well, and thermodynamic investigation revealed that the adsorption of MG by tea stalk powder was feasible, endothermic, and spontaneous. Regeneration/adsorption experiments showed that the tea stalk powder retained more than 95% efficiency after six cycles using NaOH as the desorbent, indicating its potential for multiple uses. In conclusion, tea stalk demonstrates significant potential as a cost-effective adsorbent for the removal of MG.

Summary: In this study, Ti3C2Tx MXene was used as an adsorbent for the removal of Malachite Green dye. The effects of adsorbent dose, pH, contact time, and dye's initial concentration on the removal efficiency were investigated. The Freundlich model was found to be the best fitting model for the adsorption isotherms, while the pseudo-second-order model was the best fit for the adsorption kinetics. The removal efficiency was found to be influenced by the adsorbent dose, pH, contact time, and dye's initial concentration.

Summary: An alternative methodology based on the combination of microextraction with flame atomic absorption spectrometry (FAAS) is reported for the determination of Pd2+ in environmental samples. The method involves the use of CTAB as a surfactant and precipitating agent to form a complex with Pd2+ in the presence of iodide. The results show that this solvent-free microextraction is simple and sensitive for the preconcentration and determination of micrograms per liter of Pd2+ in various environmental samples.

Summary: A promising new activated carbon was produced from corncobs using boric acid-based chemical activation. This activated carbon showed good adsorption capacity for both organic pollutant methylene blue and inorganic pollutant cadmium ions. The adsorption mechanisms of these pollutants on the activated carbon were discussed, considering factors such as pH, thermodynamics, and regeneration parameters. The results showed that the adsorption of cadmium ions was affected by pH and primarily occurred through electrostatic interaction, while the adsorption of methylene blue was pH-independent and involved pi-pi dispersion forces and partial hydrogen bonding. The study also revealed that temperature had a positive effect on the adsorption of both pollutants. The activated carbon demonstrated high adsorption capacities for methylene blue and cadmium ions.
