The coupling of diazotized /i-aminoacetophenone (DPAAP) with imidazole forms the basis of the differential pulse adsorption stripping voltammetry (DPASV) method for detection of histidine and its metabolites. The absorption of azo-histidine was found to obey Frumkin absorption isotherm <1999TAL319>. [Pg.198]

Sodium (Na), potassium (K), magnesium (Mg), and calcium (Ca), concentrations were measured by atomic absorption spectrophotometry (Perkin Elmer 2380 equipped with deuterium background corrector). Cd, Zr, and Cu concentrations were obtained in a quartz cell, by differential pulse anodic stripping voltammetry (DPASV) with a assy carbon thin-film mercury covered electrode (Tacussel polarographic equipment fitted with a Tacussel EDI type electrode). Pure water was produced by a Milli. Q water purification system (Millipore). Chlorate, sulfate and carbonate were measured using classical methods. [Pg.770]

As mentioned before, two interlaboratory studies were organised prior to certification, involving ca. 15 laboratories using techniques such as cold vapour atomic absorption spectrometry, direct current plasma atomic emission spectrometry (DCP-AES), differential pulse anodic stripping voltammetry (DPASV), microwave plasma atomic emission spectrometry (MIP-AES), electrothermal atomic absorption spectrometry (ETAAS) and neutron activation analysis with radiochemical separation (RNAA).

Pinijsuwan et al. [65] loaded streptavidin-coated latex particles with biotin-coated Au-NPs so as to increase the quantity of Au-NPs. Then, they attached the latex particles to biotinylated DNA probes for coli previously hybridized to a DNA-modified SPE (Fig. 4.10). The detection step involved the immersion of the modified SPE in a HBr/Brz solution, and further differential pulse anodic stripping voltammetry (DPASV) of Au + ions. Following this methodology, a detection limit of 0.5 fM was achieved. [Pg.126]

In international intercomparison programs for the determination of Cd-B and Cd-U, GFAAS was by far the most used method [49,57]. This was also concluded in a review about Cd-B [50]. Other methods used for Cd-B were flame atomic absorption spectrometry (FAAS) with Delves cup [51] or punched paper disk [52], and differential pulse anodic stripping voltammetry (DPASV) [53]. Other methods used for Cd-U were FAAS with Delves cup [51], flame atomic fluorescence spectrometry [58], and DPASV after wet digestion [59]. For Cd-U in the past many modifications of the GFAAS method existed, e.g., extraction with ammonium pyrrolidine dithiocarbamate (APDC) or another compound [60,64], with ammonium dihydrophosphate and Triton-X [61], with diammonium hydrophosphate and nitric acid [62], with water dilution or direct [54,63], and with nitric acid dilution [54,65-67].

As discussed in recent reviews [63-66], graphite furnace atomic absorption spectrometry (GFAAS) and differential pulse anodic stripping voltammetry (DPASV) are practical, reliable techniques that furnish the requisite sensitivity for measurement of nickel concentrations in biological samples. The most practical analytical technique for the determination of nickel in biological specimen... [Pg.512]
