Applications inorganic analysis

Inorganic Analysis Redox titrimetry has been used for the analysis of a wide range of inorganic analytes. Although many of these methods have been replaced by newer methods, a few continue to be listed as standard methods of analysis. In this section we consider the application of redox titrimetry to several important environmental, public health, and industrial analyses. Other examples can be found in the suggested readings listed at the end of this chapter. 

The scientific interests of Anatoly K. Babko ranged widely, especially in regard to fundamental aspects of analytical chemistry, applications of organic reagents in inorganic analysis, chemistry of complex compounds (including heteropolyacids), analytical applications of complex compounds in photometry, luminescence and chemiluminescence, ion chromatography, and liquid-liquid extraction. 

This is primarily engaged in analysis of boiler water treatment matters and involves on-site studies of various problems and the chemical examination of corrosion products, boiler scales, etc. It can also carry out certain types of metallurgical, fuel and inorganic analysis. Normal wet methods of analysis coupled with a visible ultraviolet and atomic absorption spectrophotometer are used for a wide range of analytical applications. Equipment in use by the engineering insurers providing these services can include an ion chromatograph, spectrometer equipment, atomic... 

Fluorimetry is generally used if there is no colorimetric method sufficiently sensitive or selective for the substance to be determined. In inorganic analysis the most frequent applications are for the determination of metal ions as fluorescent organic complexes. Many of the complexes of oxine fluoresce strongly aluminium, zinc, magnesium, and gallium are sometimes determined at low concentrations by this method. Aluminium forms fluorescent complexes with the dyestuff eriochrome blue black RC (pontachrome blue black R), whilst beryllium forms a fluorescent complex with quinizarin.

Applications Table 8.58 shows the main fields of application of inorganic mass spectrometry. Mass-spectrometric techniques find wide application in inorganic analysis, and are being used for the determination of elemental concentrations and of isotopic abundances for speciation and surface characterisation for imaging and depth profiling. Solid-state mass spectrometry is usable as a quantitative method only after calibration by standard samples. 

In the gas and liquid phases, very well-established CL reactions exist that have been chronologically introduced in Chapter 1, together with their mechanisms they will be treated in different chapters of this book. Particularly, some chapters include descriptions of the CL systems and applications in the liquid phase in organic and inorganic analysis (Chapters 5 and 6, respectively), for BL systems (Chapter 10) applications derived from the use of organized media (Chapter 11) the specific study of the mechanism and applications of a widely applied CL system based on the reaction of peroxyoxalates (Chapter 7) kinetics... 

The aim of this chapter is to briefly introduce the methodology and application of CL-based techniques to the analysis of inorganic analytes. Since the number of relevant CL papers on inorganic analysis is large, only keynote references... 

Because of its exceptional selectivity, sensitivity and speed, IC is particularly suited to applications involving analysis of anions and cations in wastewater, natural waters, source effluents, workplace environments, ambient air and rain water. The analysis of organic as well as inorganic ions can be performed by 1C. Table I is a growing list of ions which have been successfully separated and detected. The principles of IC and selected applications to environmental pollutants are described in this paper. 

The application of high temperatures to increase the speed of HPLC separation extends to ion chromatography and to inorganic analysis. Le et al. [18,19] reported a 50% reduction in analysis time when a number of selenium and arsenic species including inorganic forms, organometallics, and compounds with amino acids and sugars were analyzed at 70°C. 

Photochemical operations offer several routes of hydroxyl radical formation by UV irradiation. The formation of hydroxyl radicals by irradiation of samples doped with hydrogen peroxide or ozone is the state-of-the-art in water treatment. Two comprehensive reviews cover the historical development of the UV photo-oxidation technique as a pretreatment step in the inorganic analysis of natural waters, its principles and the equipment available, and its principal applications in the analytical field.3,4 They include tables summarizing the elements determined, the analytical techniques used, and the sample matrices studied. 

Mobile phases useful for suppressed conductivity detection of anions include sodium hydroxide, potassium hydroxide, and the sodium and potassium salts of weak acids such as boric acid. In nonsuppressed conductivity detection, the ionic components of the mobile phase are chosen so that their conductivities are as different from the conductivity of the analyte as possible. Large ions with poor mobility are often chosen, and borate-gluconate is popular. For cations, dilute solutions of a strong acid are often used for nonsuppressed conductivity detection. For more information on the application of electrochemical detection to inorganic analysis, see Ion Chromatography Principles and Applications by Haddad and Jackson,17 which provides a comprehensive listing of the sample types, analytes, sample pretreatments, columns, and mobile phases that have been used with electrochemical detection. 

The procedures referred to in this article are not applicable for analysis of ricin. Analysis of some of the scheduled inorganic chemicals may also require special approach. These are (by the Schedule number) the chemicals 2.B.7, 3.B.5, 3.B.6, 3.B.7, 3.B.12, 3.B.13, and 3.B.14. Riot control agents are not included in the Schedules, but are analyzable with the methods presented. 

Mass spectrometry is not only an indispensable tool in organic and biochemical analysis, but also a powerful technique for inorganic analysis [89-91]. Indeed, over the last 20 years the application of mass spectrometry to inorganic and organometallic compounds has revolutionized the analysis of these compounds. Important advances have been made in the diversification of ionization sources, in the commercial availability of the instruments and in the fields of applications.
