Chromium Removal from Aqueous Solution Using Natural Clinoptilolite

Water, Journal Year: 2023, Volume and Issue: 15(9), P. 1667 - 1667

Published: April 25, 2023

This work investigates the applicability of clinoptilolite, a natural zeolite, as low-cost adsorbent for removing chromium from aqueous solutions using fixed bed studies. To improve its removal performance inorganic pollutant, is pretreated with NaCl to prepare it in homoionic form Na+ before undertaking ion exchange Cr3+ solution. also evaluates if treated effluents could meet required effluent discharge standard set by legislation target pollutant. sustain cost-effectiveness wastewater treatment, spent regenerated NaOH. It was found that clinoptilolite has two-times higher Cr adsorption capacity (4.5 mg/g) than as-received (2.2 mg/g). Pretreatment enabled treat more volume (BV) (64 BV) at breakthrough point 0.5 mg/L concentration and achieve longer time (1500 min) first run, compared (32 BV; 250 min). suggests pretreatment rendered Na+. Although an initial 10 mg/L, were still unable limit less 0.05 US Environmental Protection Agency (EPA).

Green synthesis of thiourea derivatives from nitrobenzenes using Ni nanoparticles immobilized on triazine-aminopyridine-modified MIL-101(Cr) MOF

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Aug. 10, 2023

Abstract Nanohybrid metal–organic frameworks (MOF) have recently been considered next-generation catalysts regarding their unique features like large surface-to-volume ratio, tailorable geometry, uniform pore sizes, and homogeneous distribution of active sites. In this report, we address the triazine-aminopyridine-modified 3D Cr-centred MOF MIL-101(Cr)-NH 2 following a post-synthetic modification approach. The excellent chelating ability triazine-aminopyridine was applied to immobilize Ni ions over host matrix MOF. as-synthesized material physicochemically characterized using various analytical techniques FT-IR, electron microscopy, EDS, elemental mapping, XRD, ICP-OES. Subsequently, has catalytically employed in synthesizing new thiourea derivatives by reacting nitrobenzene phenyl isocyanate. catalyst isolated centrifugation recycled 6 consecutive runs without momentous loss its reactivity.

Recent Progress in Conjugated Polymers-Based Donor–Acceptor Semiconductor Materials for Photocatalytic Hydrogen Evolution from Water Splitting

Catalysts, Journal Year: 2023, Volume and Issue: 13(5), P. 850 - 850

Published: May 8, 2023

Exploration of high-efficiency stabilization and abundant source-conjugated polymers semiconductor materials with suitable molecular orbital energy levels has always been a hot topic in the field photocatalytic hydrogen evolution (PHE) from water splitting. In recent years, constructing intramolecular donor–acceptor (D–A)-conjugated architecture copolymers proved as one most excellent photocatalyst modification tactics for optimizing PHE properties because unique advantages, including easy regulate band-gap position, fast transfer charge carrier architecture, superior sunlight absorption capacity range, large interfacial areas, so forth. Therefore, this minireview, we summarize latest research progress D–A First, briefly overview fundamental description principles construction heterostructures system. After that, application reaction over different classes organic semiconductors have discussed detail. At last, present development prospects future potential challenges are proposed. We hope minireview some parameter values further developments intermolecular special structured material research.
