Book Description
Iron in small quantities and trace amounts may be determined quantitatively by complexing with pyridine and/or phenanthroline compounds. Distinct colors are produced by ferrous ions and ferric ions. Spectrophotometric methods are presented for their determination singly or in combination, and in the presence of other metals and substances. (Author).

Book Description
Aquatic chemists and by extension the public sector have a fundamental methodology through which they can determine serious metal concentrations in liquid. This thesis discusses the use of hydroxylamine coordination compounds followed by the complexation with the ligand; one and 10-phenanthroline as the technique for the determination of iron concentration in solutions. Technique used is spectrophotometry. From the analysis, it was established that iron(II) and iron(lll) demonstrate different properties when reacted. In this regard, the spectrophotometric analysis conducted was a success in identifying and differentiating between the two solutions of iron with different oxidation states --

Book Description
The book covers specific and selective reagents for the determination of iron and copper by spectrophotometry. It provides methods for each group or class of reagents, including conditions, wavelength and interferences of other ions in samples. It is a unique guide for researchers in analytical chemistry from pharmaceutical to environmental monitoring laboratories working on iron and copper based products.

Book Description
Spectrophotometry enables one to determine, with good precision and sensitivity, almost all the elements present in small and trace quantities of any material. The method is particularly useful in the determination of non-metals and allows the determination elements in a large range of concentrations (from single % to low ppm levels) in various materials.In Separation, Preconcentration and Spectrophotometry in Inorganic Analysis, much attention has been paid to separation and preconcentration methods, since they play an essential role in increasing the selectivity and sensitivity of spectrophotometric methods. Separation and preconcentration methods have also been utilised in other determination techniques.Spectrophotometric methods which are widely used for the determination of the elements in a large variety of inorganic materials are presented in the book whilst separation and preconcentration procedures combined with spectrophotometry are also described. This book contains recent advances in spectrophotometry, detailed discussion of the instrumentation, and the techniques and reagents used for spectrophotometric determination of elements in a wide range of materials as well as a detailed discussion of separation and preconcentration procedures that precede the spectrophotometric detection.
