Atomic absorption spectrophotometric determination of mercury in undigested biological samples.

A rapid method for estimating mercury in undigested biological samples.

Magos, L., and Cernik, A. A. (1969). Brit. J. industr. Med., 26, 144-149. A rapid method for estimating mercury in undigested biological samples. A method has been developed for estimating mercury in biological samples using an ultraviolet mercury detector, after liberating the mercury from the urine and other biological samples by a simple chemical method. The overall time for one estimation i...

Determination of mercury by atomic-absorption spectrophotometry.

A flameless atomic-absorption system has been developed for the determination of low concentrations of mercury in gaseous, solid and liquid samples of organic and inorganic materials.

Spectrophotometric determination of Dalacin phosphate from formulations using reduce atomic absorption of calcium ion by phosphate

A simple, sensitive and accurate method for spectrophotometric determination of Dalacinphosphatehas been established. The method is based on the reduction of atomic absorptioncalcium ion by phosphate. Because, there is a phosphate mole in every Dalacin mole structureand with measurement of phosphate, Dalacin is beyond measurement too. Therefore, the reactionbetween acidic hydrolysis products of...

Spectrophotometric determination of arsenic in environmental and biological samples

A simple and sensitive spectrophotometric method has been developed for the determination of arsenic using variamine blue as a chromogenic reagent. The method is based on the reaction of arsenic(III) with potassium iodate in acid medium to liberate iodine, which oxidizes variamine blue to form a violet coloured species having an absorption maximum at 556 nm. Beer’s law is obeyed in the range 0....
