AI Article Synopsis
- Organic arsenic is a dangerous carcinogen commonly found in animal feed and wastewater, making its detection critical for health and safety.
- The study presents HNU-62, a newly developed coordination polymer that uses a special hydrophobic fluorescent ligand to effectively detect roxarsone (ROX) in water with a limit of detection of 4.5 × 10 M.
- HNU-62 demonstrates excellent anti-interference properties and can be reused, making it suitable for testing real samples, such as pig feed, and showcasing a new method for creating stable fluorescent sensors.
Article Abstract
Organic arsenic, usually found in animal feed and livestock farm wastewater, is a carcinogenic and life-threatening substance. Hence, for the rapid and sensitive detection of organic arsenic, the development of new fluorescent sensors is quite essential. Here, an acid-base stable coordination polymer (HNU-62) was constructed by the introduction of hydrophobic fluorescence ligand, which can be used as a highly selective sensor for the detection of roxarsone (ROX) in water. The limit of detection (LOD) of HNU-62 for ROX was 4.5 × 10 M. Furthermore, HNU-62 also exhibits good anti-interference and recyclability, which can be used in detecting ROX in real samples of pig feed. This work provides an alternative approach for the construction of water-stable coordination polymer-based fluorescence sensors.
