“…Conventional elemental analysis techniques like inductively coupled plasma-optical emission spectrometry (ICP-OES), [8,9] ICPmass spectrometry (ICP-MS), [10][11][12] flame atomic absorption spectrometry (FAAS) [7,13,14] and graphite furnace atomic absorption spectrometry (GFAAS) [15,16] have been widely used for heavy metal determination. Even though FAAS is the most regularly used heavy metal detection system among these methods, the system sensitivity is insufficient to detect trace and ultra-trace levels of heavy metals.…”

“…5 The European Food Safety Authority (EFSA) and the United States Food and Drug Administration restrict the concentration of azo food dyes in commercial products to ensure an innocuous supply to consumers. 6–8…”

“…5 The European Food Safety Authority (EFSA) and the United States Food and Drug Administration restrict the concentration of azo food dyes in commercial products to ensure an innocuous supply to consumers. [6][7][8] Several analytical detection techniques have been established to detect and eliminate TRZ, which include thin-layer chromatography, 9 high-performance liquid chromatography, 10 capillary electrophoresis, 11 and spectrophotometry. Recently, chromatographic techniques have been integrated with other analytical tools to determine azo food dyes; for instance, LC-UV-Vis and LC-MS have been used to analyze various food matrices.…”

A dual functional turn off florescence sensor using metal–organic framework for sensitive detection of aluminum(III) in aqueous solution

“…Recognizing the paramount importance of prevention, employing reliable and precise techniques for the detection of these ions is crucial. However, many commonly used detection techniques are both expensive and challenging to implement, such as liquid chromatography [11][12][13][14][15], atomic absorption spectroscopy (AAS) [16][17][18], inductively coupled plasma mass spectrometry (ICP-MS) [19][20][21], and so forth. However, the fluorescence technique has gained significant appeal in recent years due to its inherent advantages, including high sensitivity, ease of operation, cost-effectiveness, and rapid detection times [22][23][24][25][26][27][28].…”
