Spectrophotometric techniques remain a frequent choice for routine analyses as they provide simple, accurate and inexpensive solutions when compared to other methods. Several spectrophotometric methods were reported in the literature for the analytical determination of titaniumIV [11-25]. These. Rapid spectrophotometric determination of trace amounts of chromium using variamine blue as a chromogenic reagent. It is known that an increase in the content of this element in soils makes them infertile and that the toxic effect depends to some extent on the oxidation state of chromium.

A new sensitive and highly selective method is described for the spectrophotometric determination of microgram amounts of vanadiumV. First, vanadium is isolated by extraction withN-benzoyl-N-phenylhydroxylamine BPHA in chloroform from about 4M hydrochloric acid medium. Then, chloroform is evaporated and the residue mineralized with mixture of cone. perchloric and nitric acid. Part II, Methods for Separation and Determination of Individual Elements, discusses all elements - both nonmetals and metals and major procedures for the separation and spectrophotometric.

INTRODUCTION The separation and determination of heavy metal ions in the environmental and biochemical research have been one of the most important topics of analytical chemistry. As compared with the other techniques, spectrophotometry is very simple, rapid and less expensive for determination of elements in a variety of samples. A spectrophotometer can be located in many studies, biology, chemistry, and industrial laboratories. The spectrophotometer is utilized for research and data evaluation in different scientific fields. Some of the major fields in which a spectrophotometer is employed are physics, molecular biology, chemistry, and biochemistry labs. Dec 09, 2003 · Abstract. Microchim.
