Overview of analytical methods for elemental speciation.
Jon C. Van Loon,R.R. Barefoot +1 more
TL;DR: A selection of the major developments in the field of analytical methodology for elemental speciation over the period from January 1986 to December 1990, as well as a number of methods for elements most frequently studied will be discussed.

Simultaneous kinetic determination of Fe(III) and Fe(II) by H-point standard addition method.
TL;DR: The H-point standard addition method (HPSAM) was applied to kinetic data for simultaneous determination of Fe(III) and Fe(II) or selective determination ofFe(III), achieving satisfactory accuracy and precision in the presence of excess Fe( II) under working conditions.

On-line determination of iron(II) and iron(III) using a spectrophotometric sequential injection system
TL;DR: In this paper, the sequential injection analysis (SIA) method was used for metal speciation analysis and the proposed method is used for the quantitative discrimination of two iron species, Fe(II) and Fe(III), respectively, with a %R.S.D. of 1.3 and 0.8% respectively.

Simultaneous determination of Fe(II) and Fe(III) by kinetic spectrophotometric H-point standard addition method
TL;DR: The proposed H-point standard addition method was successfully applied for simultaneous determination of Fe(II) and Fe(III) in several environmental and synthetic samples with different concentration ratios of Fe-II and Fe-III.

Simulataneous determination of nitrite and nitrate in water using flow-injection biamperometry
TL;DR: In this article, two polarized platinum wire electrodes were used for detection of iodide by nitrate in a reductor minicolumn containing copperized cadmium, where reduction of nitrate to nitrate occurs and the effects of interfering species such as Cu(II), Fe(III), Cr(VI) and residual chlorine were examined.

Simultaneous determination of nitrate and nitrite by flow injection analysis
TL;DR: In this paper, an automatic method for the simultaneous determination of nitrate and nitrite by flow injection analysis is described, where nitrate is reduced to nitrite with a copperized cadmium column and diazotized with N -(l-naphthyl)ethylenediammonium dichloride.
