Anodic Stripping Voltammetry with Photochemical Preconcentration at Nanocrystalline TiO2 Films: Detection of Ag+ and Hg2+

Development of a photoelectrochemical sensor for detection of TBHQ antioxidant based on LiTCNE-TiO2 composite under visible LED light

“…Pioneering works in the development of photoelectrochemical sensors have opened new perspectives in application of novel materials with excellent photoelectrochemical properties including the promising quantum dots [17][18][19] and titanium dioxide (TiO 2 ) [20][21]. Over the past decades, TiO 2 has been applied in many promising areas ranging from photovoltaics, photocatalysis, to photoelectrochemical sensors [22][23][24].…”

A highly sensitive aptamer method for Ag+sensing using resonance Rayleigh scattering as the detection technique and a modified nanogold probe

“…3,4 Therefore, it is important for environmental protection and human health to establish a Ag + detection method, which has high sensitivity, high selectivity and low cost. At present, the methods of measuring Ag + mainly include atomic absorption spectrometry, 5,6 voltammetry, 7,8 inductively coupled plasma atomic emission spectrometry, 9,10 inductively coupled plasma mass spectrometry, 11,12 ion selective electrode methods, 3,4 fluorescence methods, [13][14][15][16] colorimetric methods 17,18 and surface plasma resonance. 19,20 Among them, atomic absorption spectrometry is suitable for determination of ultratrace silver 5 in water environments with a detection limit of 1.2 ng L 21 .…”
