The surrounding environment is largely contaminated with phenols, and consequently qualitative and quantitative determination of phenols in water is of interest. In the current report, a low cost, naked-eye, portable and disposable cellulosic strips-based sensor was fabricated to detect phenols in aqueous media. The cellulosic filter paper was mole...

The preparation of aggregation-induced emission-type copper nanoclusters (CuNCs) capped with polydopamine (PDA) is described. PDA was formed via in situ polymerization of dopamine in the presence of alkaline polyethylenimine. The PDA-capped CuNCs (PDA-CuNCs) exhibit orange fluorescence with maximal emission at 580 nm upon excitation at 340 nm, a st...

Simultaneous fluorometric determination of iron(III) and copper(II) without the use of any masking agent or additional treatment is achieved by using N-doped carbon dots (NCDs). The NCDs were hydrothermally prepared, have strongest excitation/emission peaks at 320/406 nm and a 47% quantum yield. Excitation-tunable emission is found to depend on sol...

The present work aimed to provide a novel chemosensor for ferric ion detection in human serum samples using nano-structured Mg-Al layered double hydroxide intercalated with salicylic acid (Mg-Al LDH-SA) as a sensitive fluorescence probe. The Mg-Al LDH-SA nanomaterial was synthesized and characterized via Fourier transform infrared spectroscopy, X-r...

Manganese-doped carbon quantum dots (MnCQDs) were prepared through one-step hydrothermal method using citric acid and manganese tetraphenyl porphyrin as carbon sources in aqueous media. The structure of MnCQDs was confirmed by TEM, XRD, and XPS. The MnCQDs display a typical excitation-dependent emission behavior and exhibit bright green luminescenc...

Copper was used as a non-inert cathode material in a Cathode/Fe3+/peroxymonosulfate(PMS) system, and the performance of this novel Cu-cathode/Fe3+/PMS system was tested with a typical iodinated X-ray contrast media (iohexol) as target organics. The reaction mechanisms and the iohexol degradation pathways were investigated. The operational condition...

Fluoride toxicity to microorganisms was a predominant factor contributing to the failure of a commercial scale bioleach heap. An integrated control strategy for fluoride complexation without jarosite generation by stepwise adding ferric ions was first proposed to enable the bioleaching of the chalcopyrite associated with fluoride-bearing gangue min...

Here, one kind of hydrophilic hydroxypropyl β-cyclodextrin cross-linked polymer (HP-CDP) was prepared and used to establish a “turn-on” fluorescent probe for selective determination of captopril in biological samples. The HP-CDP has been synthesized in one step by cross-linking (2-hydroxypropyl)-β-cyclodextrin (HP-β-CD) with a rigid aromatic group ...

A pH-dependent selective ion exchange coupled with catalytic polymerization of aniline has been developed for sensitive detection of copper (Cu2+) and ferric ions (Fe3+). Ethylenediamintetraacetic acid (EDTA) chelated with nickel ion (Ni2+) were intercalated in a layered double hydroxide via a co-precipitation reaction. The product was subsequently...

In this study, nitrogen and sulfur co-doped carbon dots (NSCDs) were fabricated by microwave-assisted one-pot synthesis using vitamin C and thiourea as precursors. The as-prepared NSCDs demonstrated excellent properties, including aqueous dispensability, strong fluorescence emission, excellent environmental stability, high selectivity, and sensitiv...
