Abstract
A sensitive method for the quantitative determination of piperazine is described. The method is precise and responds linearly from 25 g to 500 mug and above of the material. The procedure is based on the formation of a complex of piperazine with reineckate in neutral or acid medium. The complex can be separated by centrifugation. It is then dissolved in acetone and estimated at 530 nm in a colorimeter. Piperazine present in trichloroacetic acid extractrs of biological samples can also be estimated by this method.
