Cuculic and Branica [788] applied differential pulse anodic stripping voltammetry to a study of the adsorption of cadmium, copper, and lead in seawater onto electrochemical glass vessels, quartz cells, and Nalgene sample bottles. Nalgene was best for sample storage and quartz was best for electroanalytical vessels. 

Batley [28] examined the techniques available for the in situ electrodeposition of lead and cadmium in estuary water. These included anodic stripping voltammetry at a glass carbon thin film electrode and the hanging drop mercury electrode in the presence of oxygen and in situ electrodeposition on mercury coated graphite tubes. Batley [28] found that in situ deposition of lead and cadmium on a mercury coated tube was the more versatile technique. The mercury film, deposited in the laboratory, is stable on the dried tubes which are used later for field electrodeposition. The deposited metals were then determined by electrothermal atomic absorption spectrometry, Hasle and Abdullah [29] used differential pulse anodic stripping voltammetry in speciation studies on dissolved copper, lead, and cadmium in coastal sea water. 

A kind of standard additions approach can also be used for the measurement of apparent complexing capacity. In this technique, labile copper is measured by differential pulse anodic stripping voltammetry after each of a number of spikes of ionic copper have been added to the sample [420].

The concentration of Cd(II) was determined using a carbon paste electrode modified with organofunctionalized amorphous silica with 2-benzothiazolethiol [402] or diacetyldioxime [403] and differential pulse anodic stripping voltammetry. The same method was used for determination of Cd(II) ion using GC electrode modified by antraquinone improved Na-montmorillonite nanoparticles [404].

Reddy and Reddy [54] used differential pulse anodic stripping voltammetry on chloroform extracts of the xanthate to determine cadmium in soil.

The determination of down to 0.02-0.25 ppm of mercury in cereals by differential pulse anodic stripping voltammetry has been discussed by Lugowska et al. [37].

The electrochemically available concentrations of Cd, Cu, and Zn, as a measure of the free ions, were analyzed for their dependence on pH and on different concentrations of calcium and fulvic acid (fa) by differential pulse anodic stripping voltammetry. A statistical experimental design in the form of a full 23-factorial plan was used to minimize...

Evidence has been detected of the biomethylation of cadmium. Studies with differential pulse anodic stripping voltammetry have shown detectable amounts of monomethylcadmium ion, H3CCd+, in surface water of the South Atlantic.5 Examination of water from some Arctic meltwater ponds showed that up to half of the cadmium present in the water was in the monomethylcadmium ion form. 

Voulgaropoulos et al used a differential pulse anodic-stripping voltammetric method for the indirect trace determination of EDTA and nitrilotriacetic acid in natural waters [22]. To the sample (50 mL, adjusted... 

The interference caused by chloride ion, Fe(III), and Cu(II) in the determination of nitriloacetic acid and EDTA in natural waters was removed by pre-treating samples (pH > 4) with cation exchangers. Some samples required additional treatment with an anion exchanger (pH 1). The analytes were complexed with Bi (III) before being determined by differential pulse anodic stripping voltammetry at the hanging mercury drop electrode (vs. Ag/AgCl. The detection limit was 0.1 pg/L for EDTA.

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.
