Ultraviolet and light absorption spectrometry

Abstract

This is a review of the developments in ultraviolet and light absorption spectrometry from December 1979 through November 1981, primarily as documented in Chemical Abstracts and CA Selects, and extends the series of reviews sponsored by Analytical Chemistry beginning in 1945 for Light Ab-

Ultraviolet and Light Absorption Spectrometry

“…This review reports the developments in ultraviolet and light absorption spectrometry from January 1994 through December 1995, primarily as documented in the Ultraviolet & Visible Spectroscopy section of CA Selects, and extends the series of reviews on these topics sponsored by Analytical Chemistry starting with Light Absorption Spectrometry in 1945 (1-3), followed by Ultraviolet Absorption Spectrometry in 1949 (4)(5)(6)(7)(8)(9) and combined Ultraviolet and Light Absorption Spectrometry in 1978 (10,11). As in the previous reviews, the subject matter is divided into sections on chemistry, physics, and applications.…”

“…A study of the usefulness of o-phenylenediamine in determination of R-dicarbonyl compounds reported quantitation at concentrations as low as 5 µM (84). A patent discloses the use of oxo [5,10,15,20-tetra(4-pyridyl)-21H,23H-porphyrinate]titan to determine peroxides as well as the use of this reagent in conjunction with an immobilized enzyme-containing column to determine glucose, galactose, pyruvate, uric acid, cholesterol, and others (85). Natural indoles were analyzed by complexation with 1,3,5-trinitrobenezene and measurement of the absorbance in the region of 460-529 nm (86).…”

Spectrophotometric determination of platinum(IV) in alloys, complexes, environmental, and pharmaceutical samples using 4-[N,N-(diethyl)amino] benzaldehyde thiosemicarbazone

“…Many complexation reactions of platinum with different ligands were investigated for the development of spectrophotometric reagents for platinum. Beamish (1966); Beamish and Van Loon (1972); Boltz et al (1966Boltz et al ( , 1968Boltz et al ( , 1970Boltz et al ( , 1972Boltz et al ( , 1974Boltz et al ( , 1976; Howell et al (1978Howell et al ( , 1980Howell et al ( , 1982Howell et al ( , 1984 have reviewed the spectrophotometric methods for the determination of platinum. A survey of literature reveals that a large number of reagents are suitable, either directly or after extraction into a suitable solvent.…”
