چکیده
Cernik, A. A. (1970). Brit. J. industr. Med., 27, 40-42. Determination of lead chelated with ethylenediaminetetra-acetic acid in blood after precipitation of protein with perchloric acid. A method is described for the determination of lead in whole blood containing ethylenediaminetetra-acetic acid. Proteins were precipitated by 2-0 M perchloric acid. The ionized lead in the supernatant was chelated with ammonium pyrrolidine dithiocarbamate and was extracted with xylene. The method agreed well with a dry ashing technique (30 samples, correlation coefficient 0-985). Perchloric acid gave consistently good recoveries, unlike trichloroacetic acid, which frequently produced losses of up to 150.

Liquid-chromatographic determination of indole-3-acetic acid and 5-hydroxyindole-3-acetic acid in human plasma.
We describe a "high-performance" reversed-phase liquid-chromatographic method for determination of indole-3-acetic acid (I) and 5-hydroxyindole-3-acetic acid (II) in human plasma. I is eluted at 1.0 mL/min with a mixture of 1-pentanesulfonic acid (pH 3.1), methanol, and water. It is detected by fluorometry. A mixture of citric acid/sodium phosphate solution (pH 4.8) and methanol, at 1.5 mL/min,...
متن کاملDetermination of lead in plasma and studies on its relationship to lead in erythrocytes.
Plasma lead concentrations were determined in 103 subjects, including lead workers and those not occupationally exposed to lead. The plasma lead concentrations in each blood lead group were about half those previously reported, and this difference was shown to be due to the use of heparin instead of ethylenediaminetetra-acetic acid (EDTA) as the anticoagulant. The method for the determination o...

متن کاملThe Comparison of Acetic Acid and Strontium Chloride Procedures for Extraction of Hemin
Abstract Background and objectives: Hemin is a porphyrin compound derived from hemoglobin, the precursor of other porphyrin hemoglobin derivatives and the raw material of Hematin. Since hemin is widely used in medicine, we decided primarily to synthesize this substance in Laboratory and to determine the best way of hemin extraction from untransfused and expired blood units. Materials and Method...
