“…Usually, trace metals are quantified by atomic absorption spectroscopy, inductively coupled plasma mass spectroscopy, and X-ray fluorescence (FL) spectroscopy . However, these methods for quantifying residual palladium are generally instrumentally intensive and performed off-site and thus require long analysis time ranging from days to even weeks.…”

Due to vast application of palladium in academia and industry and its toxicity, it is critical to develop user-friendly, portable, and affordable methods for accurately detecting ultratrace Pd. In this study, a highly sensitive and selective fluorescent probe (N-butyl-4-alloxy-1,8-naphthalimide, compound 2) was synthesized, which demonstrated multiple signals [enhanced fluorescence (FL), ratiometric FL, and colorimetric responses] upon interaction with palladium. The compound 2 was designed by incorporating a naphthalimidebased fluorescent dye as the fluorophore and an allyl ether group as a responsive unit. Utilizing a Pd 0 -triggered cleavage reaction by a deallylation reaction through the Tsuji−Trost reaction, compound 2 exhibited rapid response, wide linearity, exceptional sensitivity with a limit of detection as low as 2.2 pM, and high selectivity toward palladium species. In addition, as a ratiometric and enhanced FL response, the probe could be developed as a portable sensor via naked eye visualization for semiquantitative and selective detection of palladium. Integrating with an easily available smartphone (with a camera and a color-analysis app), potential in situ quantitative detection was achieved at a low cost. The probe shows multiple signals for palladium detection and potential as a portable sensor, and this work provides valuable insights into developing sensors with good sensitivity, selectivity, improved reliability, and portability for detection of palladium and other analytes of interest.

“…Due to the increased use and toxicity of Pd compounds for mammals, fish and higher plants, it is very important to extract and determine Pd 2+ in the environment. This monitoring can also be lead to the discovery of ore resources [ 3 ]. Various methods such as liquid-liquid extraction [ 4 ], membrane filtration [ 5 ], and ion exchange [ 6 ] have been used for the extraction of Pd 2+ ions.…”

In this research, a novel magnetic zirconium-based metal-organic framework (Fe3O4@SiO2@MIP-202, MMOF), was fabricated, fully characterized, and applied for the batch-mode solid phase extraction of trace amounts of Pd2+ ions from water and wastewater samples before its spectrophotometric detection. Pd2+ ions were desorbed from MMOF by nitric acid and were complexed by treating with KI solution to have a maximum absorbance at 410 nm. The synthesized MMOF composite showed a very large surface area (65 m2.g− 1), good magnetization (1.7 emu.g− 1) and a large pore volume (0.059 cm3.g− 1) with adsorption capacity of 194.5 mg of Pd2+ ions/g of the adsorbent. This nanosorbent boasts chemo-mechanical stability, high adsorption capacity due to its vast active sites, and facile recovery facilitated by its magnetic properties. Parameters affecting the extraction efficiency of the method were optimized as pH of the sample 7.4, volume of the sample 25 mL, 15 mg adsorbent, 1 mL of 0.1 M HNO3 eluent, with 10 and 15 min as the extraction and desorption times, respectively. The calibration curve was found to be linear across the 10.0–1500.0 µg.L− 1 range with a limit of detection of 1.05 µg.L− 1. The obtained extraction efficiency and enrichment were 98% and 245, respectively. The total analysis time was less than 30 min. This MMOF has never been used for the extraction of Pd2+ ions before.

MXene quantum dots (MQDs), an emerging zero‐dimensional nanomaterial, have garnered significant attention from researchers due to their distinctive physical and chemical properties. In this study, cysteine‐functionalized Ti3C2 MQDs were synthesized using a facile hydrothermal methods, resulting in the functionalized Ti3C2 MQDs exhibiting intense blue fluorescence attributed to size‐dependent effects and surface defects. Furthermore, the cysteine‐functionalized Ti3C2 MQDs exhibit excitation wavelength‐dependent emission behavior and serve as a highly sensitive fluorescent probe for Ag+ detection with an impressive low limit of detection (LOD) of 0.015 μM. Moreover, they demonstrate exceptional sensitivity and selectivity in determining Ag+. This study presents a novel approach for the detection of Ag+ and highlights the immense potential of cysteine‐functionalized Ti3C2 MQDs in environmental applications.
