Flow-Injection Photometric Determination of Mercaptans in Light Oil Products by Extraction / Preconcentration with Chromatomembrane Cell

Original Paper

Abstract

The method for flow-injection photometric determination of mercaptans in light oil products extracting mercaptans into aqueous sodium nitroprusside solution containing borate buffer with chromatomembrane cell, following the detection of colored reaction product formed (λ = 540 nm) has been developed. Detection limit is 1 mg S/L when 3 ml of sample volume is used.
