Ag@MOF-199 metal organic framework for selective detection of nickel ions in aqueous media

Development of substrate free polymer composite for Pb2+ ion sensor

“…Certain metals serve as essential components for various metallo-proteins, but their accumulation can lead to human body disorders, particularly neurological issues. The detection of heavy metal ions (HMI) is crucial for environmental and food analysis due to severe health risks they pose [5][6][7][8][9]. Among the harmful metals, lead has received special attention due to its high toxicity and environmental impact [10].…”

“…For direct water analysis, electrochemical sensors offer a practical, cost-effective and user-friendly alternative [4]. Electrochemical techniques have gained popularity due to their ability to provide effective selectivity and high sensitivity in quantifying HMIs [5,9,13]. Electrochemical sensors represent a captivating and widely explored field in environmental analysis.…”

Chemiresistive Sensor Based on Metal Organic Framework-Reduced Graphene Oxide (Cu-BTC@rGO) Nanocomposite for the Detection of Ammonia

“…Cu-BTC was synthesized with the hydrothermal method, as reported elsewhere [10]. Briefly, 2.252 g of copper nitrate trihydrate and 0.982 g of trimesic acid were added in 50 mL of DI and DMF, respectively.…”

Calcination-induced enhancement of Cd2+ and Pb2+ electrochemical detection capabilities of nano-ag-supported CoZn bi-metal ZIFs

“…However, due to their poor conductivity and instability in aqueous solutions, 11 MOFs are usually combined with noble metals, such as Au, Ag, Pt, to construct new composite materials in order to enhance their electrochemical activities. [12][13][14] Gajanan A. Bodkhe et al 15 incorporated silver nanoparticles (Ag NPs) into a carboxylic acid copper MOF (MOF-199), and the obtained composite (Ag@MOF-199) showed good electrochemical detection performance for Ni 2+ in water. Qianyun Bin et al 16 decorated Ag NPs into the cavities of Zn zeolitic imidazolate framework (ZIF-8) to prepare Ag/ZIF-8 composites for the electrochemical sensing of Cl − .…”
