ELLMAN'S REAGENT FOR ANALYSIS OF o-CHLOROBENZYLIDENE MALONONITRILE (CS RIOT CONTROL AGENT) IN SOLID SAMPLES

ABSTRACT We propose a new method of spectrophotometric determination of o-chlorobenzylidene malononitrile (CS riot control agent) in solid samples of various origins and compositions (soil, brickwork, silica gel, glass wool). The method is based on colouring reaction of malononitrile with Ellman...
