Materials interacting with inorganic selenium from the perspective of electrochemical sensing

Abstract

Inorganic selenium, the most common form of harmful selenium in the environment, can be determined using electrochemical sensors which are compact, fast, reliable and easy-to-operate devices. Despite the progress in...

Ultrasensitive and selective fluorescence recognition of selenite by o-phenylenediamine functionalized carbon quantum dots

“…Numerous analytical techniques were constructed and developed to detect SeO 3 2À , including spectrophotometry, 19 fluorescence spectroscopy, 20 gas chromatography, 21 high performance liquid chromatography, 22 mass spectrometry, 23 atomic absorption spectroscopy, 24,25 catalytic kinetic spectrophotometric method, 26 inductively coupled plasma atomic emission spectrometry (ICP-AES), 27 stripping voltammetry, 28 neutron activation analysis (NAA), 29 and electrothermal atomic spectroscopy. 30 However, most of these analytical methodologies relied upon expensive instrumentation, professional labor and complicated laborious procedures, which limited their universal and widespread applications.…”

Fabrication of functional group-rich monoliths for magnetic field-assisted in-tube solid phase microextraction of inorganic selenium species in water samples followed by online chromatographic determination

“…Selenium (Se) is a vital metalloid for the human body, wherein it balances the redox and immune systems, displaying anti-carcinogenetic effects. 1 However, Se presents a very narrow content range from essentiality to deficiency, and toxic effects. 2 In addition, the reactivity, toxicity and bioavailability of Se are strongly related to its chemical species and contents.…”
