METHOD FOR QUANTITATIVE DETERMINATION OF 10-CHLORINE-9,10-DEHYDROPHENARSAZINE IN A SOLUTION DUE TO GAS CHROMATOGRAPHY AT ATOMIC-EMISSION DETECTING

摘要

FIELD: medicine, ecological monitoring. SUBSTANCE: method deals with elaborating a high-sensitive method for quantitative determination of 10-chlorine-9,10- dehydrophenarsazine in benzene solution. Chemical modification of analyzed compound is used due to treatment with acetyl chloride in benzene at concentration of 5 M/l at 60 5 C during time interval of 2.5 0.5 h to obtain a chromatographed derivative registered at 510^-5 mg/ml sensitivity due to gas chromatography at atomic- emission detecting. EFFECT: higher efficiency. 1 cl, 4 dwg, 3 tbl, 1 ex
