The determination of metals in blood serum by atomic absorption spectroscopy-I
نویسندگان
چکیده
Abstm&-The celcium content of blood mrum cm be accurately determined on 0.1-0.25 ml samples by atomic absorption measurements in an air-acetylene flame after removal of the proteins by coagulation and centrifuging. A fairly accurate value can be obtained more quickly from direct measurements on serum diluted with water, which may with advantage contain about 1 per cent of the disodium salt of ethylenediaminetetracetic acid. Serum calcium values obtained by atomic absorption spectroscopy are signifkantly higher than those obtained by the standard oxalate-permanganate procedure and support the conclusions of MACINTYRE [3] on the shortcomings of the chemical method.

A new and simple method followed by atomic absorption spectrometry has been developedfor indirect determination of ascorbic acid (AA). The proposed method was based on the oxidationof AA to dehydroascorbic acid with Cu2+cation(200mgL-1)in an ammonium thiocyanatesolution atpH2.4. AA reduces Cu2+to Cu+followed by the precipitation of Cu+ with SCN-. Then, the excess ofCu2+in the solution was measu...
