Determination of trace elements and heavy metals in a lake sediment by neutron activation analysis

Review—Metal-Organic Frameworks Composites for Electrochemical Detection of Heavy Metal Ions in Aqueous Medium

“…[3][4][5][6][7][8] Over the past few decades, massive, exclusive, and high-level lab-based techniques, including atomic absorption spectroscopy (AAS), 9 liquid-liquid extraction, 10 flame atomic absorption spectrometry, 11 and neutron activation analysis (NAA) were used to detect the HMIs. 12 However, some of the approaches mentioned above are expensive and require a trained person, and it takes a long time to finish the experimental process. Furthermore, chemical and physical reactions (cloud point extraction, 13 and magnetic solidphase extraction, 14 ) during the transportation, processing, and pretreatment of samples can significantly alter the physicochemical characteristics of the sample and lead to incorrect results.…”
