A novel flow-injection chemiluminescence (CL) method for the determination of dihydralazine sulfate (DHZS) is described. The method is based on the reaction between DHZS and hexacyanoferrate(III) in alkaline solution to give weak CL signal, which is dramatically enhanced by eosin Y. The CL emission allows quantitation of DHZS concentration in the range 0.02-2.8mugml(-1) with a detection limit (3sigma) of 0.012mugml(-1). The experimental conditions for the CL reaction are optimized and the… CONTINUE READING
