“…Absolute quantification can then be obtained by means of VIMP [182]. A particular type of data analysis, the H-point standard additions method, can be used for the absolute quantification of two components displaying highly overlapping voltammetric signals [183,184]. An inner standard has been also used to quantify redox centres in complex hexacyanometalates [173].…”

Solid state electroanalytical chemistry (SSEAC) deals with studies of the processes, materials, and methods specifically aimed to obtain analytical information (quantitative elemental composition, phase composition, structure information, and reactivity) on solid materials by means of electrochemical methods. The electrochemical characterization of solids is not only crucial for electrochemical applications of materials (e.g., in batteries, fuel cells, corrosion protection, electrochemical machining, etc.) but it lends itself also for providing analytical information on the structure and chemical and mineralogical composition of solid materials of all kinds such as metals and alloys, various films, conducting polymers, and materials used in nanotechnology. The present report concerns the relationships between molecular electrochemistry (i.e., solution electrochemistry) and solid state electrochemistry as applied to analysis. Special attention is focused on a critical evaluation of the different types of analytical information that are accessible by SSEAC.

“…Absolute quantifi cation could in principle be performed using VMP upon adding a known amount of metal standard, a methodology applied to hexacyanoferrates [93] and minerals [94,95]. Standard addition experiments have been described for absolute quantifi cation of pigments and ceramic materials [96][97][98]. Arjmand and Adriaens have recently provided a VMP method for electrochemical quantifi cation of copper alloys with a detailed account of optimal conditions [99].…”

“…Recently, Doménech-Carbó and coworkers developed a square wave voltammetric method for the determination of boron in geological samples. However, that method is limited to samples that contain only zinc (Zn), and are free from other metals, such as copper, that form intermetallic compounds with boron and Zn (Doménech-Carbó et al 2004). Therefore, for a suitable voltammetric determination method, boron should be converted to a complex structure with a ligand bearing electroactive group by a relatively rapid complex formation reaction.…”

A sensitive voltammetric method for the determination of trace boron, based on the formation of the complex of boric acid with 4-hydroxy-5-[salicylideneamino]-2-7-naphthalenedisulfonic acid (azomethine H) is described. The reduction of the boric acid-azomethine H complex at a hanging mercury drop electrode was exploited by square wave voltammetry (SWV) and cyclic voltammetry to determine boron in natural water samples, which were collected in the regions surrounding the boron mines of Central Anatolia. A reduction peak that belongs to the boric acid-azomethine H complex at this electrode was observed at 21.05 V vs. Ag/AgCl/KCl (sat.) . The effects of various parameters, such as ligand concentration, boric acid concentration, and formation time of the boric acid-azomethine H complex, were investigated. Electrochemical experiments were conducted in 1.0 M HOAc/0.5 M NH 4 OAc buffer at pH of 4.4 + 0.2. Linear working range was established by regression analysis between 5.0 Â 10 28 M and 1.0 Â 10 24 M. The probable metal cation interferences in water samples were eliminated by adding EDTA (ethylenediaminetetraacetic acid) to the samples. Data obtained using the square wave voltammetric (SWV) technique was compared statistically with inductively coupled plasma mass spectroscopy (ICP-MS) data. Evaluation of the method based on statistical data was 2835 performed and the values of the limit of detection (LOD) and limit of quantitation (LOQ) were found to be 4.17 Â 10 26 M and 1.39 Â 10 25 M, respectively.
