FIELD: medicine, sanitary toxicology. SUBSTANCE: patient's urinary sample should be supplemented with sodium chloride salting out agent to perform its alkalization with 10%-sodium hydroxide solution up to pH = 8 - 10, carry out extraction of chlorobenzene out of the sample due to its extraction with heptane, separate the extract due to centrifuging, carry out its studying by gas chromatography assay. As for chlorobenzene quantity it should be established by calibrating diagram. Optimal centrifuging modes are those of 2700 rot. /min at 15 min centrifuging terms. EFFECT: higher sensitivity and accuracy of detection. 1 cl, 1 ex, 3 tbl |
