Adsorptive cathodic stripping voltammetry has an advantage over graphite furnace atomic absorption spectrometry in that the metal preconcentration is performed in situ, hence reducing analysis time and risk of contamination. Additional advantages are low cost of instrumentation and maintenance, and the possibility to use adapted instrumentation for online and shipboard monitoring. [Pg.168]

Platinum was determined in seawater by adsorptive cathodic stripping voltammetry in a method described by Van den Berg and Jacinto [531]. The formazone complex is formed with formaldehyde, hydrazine, and sulfuric acid in the seawater sample. The complex is adsorbed for 20 minutes at -0.925 V on the hanging mercury drop electrode. The detection limit is 0.04 pM platinum. [Pg.209]

Nitrite alternatively may be determined via the diazotization with sulfanilic acid followed by the coupling with N-(l-naphthyl)ethylenediamine dihydrochloride, detection limits being 10 moll . Possible enhancement of the sensitivity could be achieved by adsorptive cathodic stripping of this complex. [Pg.3752]

Adsorptive cathodic stripping voltammetry (ACSV) is a very sensitive technique for the analysis of numerous trace metals ( 40), which cannot be determined using conventional electrolytic stripping procedures (i.e., ASV). ACSV makes use of a specific added ligand (AL), which is added to the water sample and forms an adsorptive complex with the trace metal(s) under investigation (reaction [IV]) ... [Pg.4953]
