TLDR
Anodic stripping voltammetry (ASV) peak currents of Pb, Zn and Cd (5 × 10−8M) in low ionic strength (1 mM), bicarbonate-buffered solutions were suppressed by increasing the pH (range 4-8), especially when NaClO, rather than KCl was used as the supporting electrolyte as mentioned in this paper.About:

Performance characteristics of suspended particulate reagent-iminodiacetate as a binding agent for diffusive gradients in thin films
TL;DR: In this paper, the performance characteristics of an alternative binding agent, suspended particulate reagent-iminodiacetate (SPR-IDA), for use with DGT methodology were investigated.

Artefacts in sorption experiments with trace metals
TL;DR: In this paper, a series of systematic sorption experiments, based on filtration and measurement by atomic absorption spectrometry (AAS), showed that metal losses to container walls and filters were unavoidable in solutions which emulate freshwaters.

In SituVoltammetric Determinations of Metal Ions in Goethite Suspensions: Single Metal Ion Systems
TL;DR: Measurements in the absence of goethite showed the applicability of the voltammetric techniques for trace analysis in a wide pH range, and the results indicated that no "high-affinity" sites are present on the surface of alpha-FeOOH.

Vlado Cuculić,Marko Branica +1 more
TL;DR: In this paper, the rates and equilibria of the adsorption of dissolved CdII, PbII and CuII (at concentration levels of 2 × 10−8 and 8 × 10-8 mol l-1) from sea-water and from a 0.55 mol l−1 NaCl model solution onto electrochemical glass and quartz cells and Nalgene [fluorinated ethylene-poly(propylene)] sample bottles with and without added glass beads at pH 6.2 and 8.1 were measured by differential-pulse anodic stripping volt

The equilibrium speciation of dissolved components in freshwater and sea water at 25°C and 1 atm pressure
TL;DR: In this paper, a data base summarising the stability constants of more than 500 complexes is used to calculate speciation pictures for 58 trace elements in model seawater (pH 8.2) and freshwaters (PH 6 and 9).

Anodic stripping voltammetry with a glassy carbon electrode mercury-plated in situ
TL;DR: In this paper, an anodic stripping technique is described in which a very thin mercury film is formed on a polished glassy carbon substrate by adding mercuric nitrate to the sample solution and electrodepositing mercury and trace metals simultaneously.

Defining the electroanalytically measured species in a natural water sample
TL;DR: In this paper, the possible definition of chemical species disolved in natural waters is discussed using electroanalytical techniques, and the time of measurement is identified as the critical parameter for determining which species in solution will be measured when using transient techniques.
