L-Aspartic acid/L-cysteine/gold nanoparticle modified microelectrode for simultaneous detection of copper and lead
2012, Thin Solid FilmsCitation Excerpt :Owing to the potential danger to the environment and human, there is a growing need for monitoring of copper (II) and lead (II) in water environment. Many methods have been investigated for the detection of copper (II) and lead (II), such as atomic absorption spectroscopy [4,5], X-ray fluorescence [6,7], mass spectrometry [8,9] and electrochemical voltammetry [10,11]. Electrochemical voltammetry has been proved to be a particularly suitable method for on-site determination of copper (II) and lead (II), due to its properties such as small in size, simple, portable, reliable and low-cost.
Detection of trace levels of lead in aqueous liquids using extractive electrospray ionization tandem mass spectrometry
2012, TalantaCitation Excerpt :Therefore, it is useful to develop novel approaches for the fast, sensitive, and reliable determination of lead in aqueous liquid samples, not only for environment assessment but also for clinical significance. Currently, representative techniques for lead detection include colorimetric assay, atomic absorption spectrometry (AAS), atomic emission spectrometry (AES), electrochemistry methods, biosensors, nuclear magnet resonance, and mass spectrometry [24–27]. Inductively coupled plasma mass spectrometry (ICP-MS) has been widely used to detect lead in biological fluids, tissues, environmental samples, and oils [28–35].
