Toxic acids produced by industries are major hazards to the environment and human health, and luminescent pyrenebased crystalline metal−organic frameworks (MOFs) demonstrate promising performance in the detection of toxic acids. Herein, two novel isostructural 3D porous lanthanide MOFs, and Ce (2); H 4 TBAPy (1,3,6,8-tetrakis(p-benzoic acid)pyrene); and DMA: N,N-dimethylacetamide) were synthesized, which showed alb topology. Based on the protonation and hydrogen bond mechanism, complex 1 could be used as a fluorescence recognition sensor for HX (X = F, Cl, Br, and I) acid solutions with different luminescence behaviors. It is worth noting that complex 1 exhibited high sensitivity in the fluorescence enhancement sensing of hydrofluoric acid, oxalic acid, and trichloroacetic acid. In particular, complex 1 had a low limit of detection (LOD) for OA (0.1 μM) and was applied to real monitoring of orange fruit samples. In addition, the PVA@1 film could selectively, sensitively, and quantitatively respond to hydrochloric acid (HCl) vapor through fluorescent quenching; due to its protonation and adsorption capacity, the LOD was 0.18 ppm. Therefore, the portable optical device, the PVA@1 film, can detect HCl gas in trace amounts, achieving the ultimate goal of real-time and rapid detection, which has potential application value for industrial production safety.

“…Herein, we choose 2,6dichloro-4-nitrophenol (2,6-DCNP) as the model compound for electrochemical sensing. The dechlorination reactions are usually used to show current signals in TCAA sensing, 30,31 while for 2,6-DCNP, the reduction of the nitro-moiety is occurs more readily in the electrochemical process, which however could be affected by the dechlorination reactions, 32 making the quantitative detection of 2,6-DCNP difficult. Also, unmodied electrodes are tardy for electron transport in electrochemical sensors.…”

“…[1][2][3] As one of the major halogenated acetic acids, TCA is easily soluble in water, harmful to human beings, animals, plants and algae, and has carcinogenic and mutagenic properties. [4][5][6] Therefore, guideline values of TCA was established as 1.22 μM in drinking water by World Health Organization (WHO). 7 In China, the absorbable organic halogen in production wastewater should not exceed 7.33 μM, and in the textile printing and dyeing wastewater should not exceed 73.44 μM.…”

Determining the content of chloroacetic acid in water is mandatory, so its rapid and accurate detection is of great significance for environmental health. Silver has a strong specific interaction with chloridion and its three-dimensional interconnected ligaments are proved to have higher activity. Herein, a self-supported nanoporous skeleton was constructed on the surface of silver wire by directly electrochemical alloying in ZnCl2-glycol solution at 140℃ and subsequently dealloying in sulfuric acid solution. AgZn and AgZn3 alloys are formed by electrodeposition process, and the nanoporous skeleton of elemental silver is formed after dealloying. The interconnected ligaments are uniform and the pore size is about 10-200 nm. The cyclic voltammetry showed that the self-supported nanoporous skeleton of the silver wire electrode exhibited high electrocatalytic activity for trichloroacetic acid. Detected by chronoamperometry, the results show that the detection limit is 70 nM (S/N = 3) in the concentration range of 0.14-549 μM, and the sensor has high sensitivity, good reproducibility and anti-interference. And by detecting the recovery rate of trichloroacetic acid in the tap water, river water and industrial wastewater, the sensor proves the practicality of the prepared electrode.
