The adsorptive removal of a pollutant from water is significantly affected by the presence of coexisting ions with various concentrations. Here, we have studied adsorption of arsenate [As(V)] by calcined Mg-Fe-(CO)-LDH in the presence of different cations (Mg, Na, K, Ca, and Fe) and anions (CO, Cl, PO, SO, and NO) with their different concentrations to simulate the field condition. The experimental results indicated that Ca, Mg and Fe have a synergistic effect on removal efficiency of As(V), whereas PO and CO ions have a significant antagonistic impact. Overall, the order of inhibiting effect of coexisting anions on adsorption of As(V) was arrived as NO˂Cl

Nickel, an essential transition metal, plays a vital role in biological systems and industries. However, exposure to nickel can cause severe health issues, such as asthma, dermatitis, pneumonitis, neurological disorders, and cancers of the nasal cavity and lungs. Due to nickel's toxicity and extensive industrial use, efficient sensors for detecting Ni ions in environmental and biological contexts are essential.

Rationale: The complexation with dissolved organic matter (DOM) is a pivotal factor influencing transformations, transport, and bioavailability of mercury (Hg) in aquatic environments. However, identifying these complexes poses a significant challenge because of their low concentrations and the presence of coexisting ions.
Methods: In this study, mercury-dissolved organic matter (Hg-DOM) complexes were isolated through solid-phase extraction (SPE) from Hg-humic acid suspensions, and complexes were putatively identified using ultrahigh resolution Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS).

This study describes the preparation of novel hybrid aerogels derived from gelatin (Gel), incorporating Br-functionalized zirconium-based metal-organic framework (UiO-66-Br; MOF) as modifying agent to effectively eliminate phosphate and fluoride ions from aqueous environments. The adsorption performance of MOF decorated Gel (Gel-xMOF) hybrid aerogels was investigated under different conditions, including agitation time, adsorbent dosage, solution pH, initial phosphate and fluoride concentrations, coexisting ions, and temperature. The functional groups of the gelatin network, coupled with UiO-66-Br, enhanced the adsorption performance of phosphate and fluoride ions from aqueous solutions.

The present study aims to analyze the thermal regulation of the Ce/Ce ratio on the nanonetwork titania layer over the titanium (Ti) surface developed by the alkali-mediated surface modification approach. The effect of sequential heat treatment from 200 to 800 °C was evaluated for its surface characteristics such as morphology, phase formation, roughness, hardness, hydrophilicity, etc. Surface oxidation by temperatures up to 600 °C demonstrated a progressive increase in the Ce (CeO) content with a rutile TiO network layer over the Ti surface.

This study employs first-principles molecular dynamics (FPMD) simulations combined with the Voronoi tessellation method to explore the microstructure, transport properties, electronic properties, and Raman spectra of the NaF-AlF-CaF/LiF/KF systems with varying cryolite ratios, additive types, and concentrations. The results indicate that Na, Ca, Li, and K exist in a free state in the molten salts, while Al forms complex ion groups in the form of [AlF] with F, and free F also exists in the molten salts. In the NaF-AlF-CaF system, the average Al-F distance is slightly shorter than that in the other two systems, while the Al-F coordination number is higher in NaF-AlF-LiF.
