An ion-imprinted polymer (IIP) quartz crystal microbalance (QCM) sensor for detection of Hg2+ in wastewater was developed. The paper focuses on sensor fabrication and characterisation; no food matrices were analysed. Primary relevance is as an analytical method paper for Hg detection.
Key numbers
- Specific LOD, linear range, and selectivity data in full paper.
- No food occurrence data.
Methods (brief)
IIP-QCM piezoelectric sensing. Measures total Hg2+ (inorganic). No speciation. Wastewater validation only.
Implications
Certification: Method development; no food data. Courses: Demonstrates QCM-based heavy metal sensing as complementary to ICP-MS for rapid screening.
