title: [Flow-injection chemiluminescence determination of procaterol hydrochloride].
abstract: A new flow injection chemiluminescences method for the determination of procaterol hydrochloride has been developed. It is based on the chemiluminescence reaction of procaterol hydrochloride with Ce (IV)-rhodamine B in sulphuric-chlorhydric acid medium and the experimental fact of the enhancement of chemiluminescence by surfactant CTMAB. The concentration of the analyte shows a good linear relationship with the produced luminescence intensity in the range of 2.0 x 10(-8) g x mL(-1) to 1.0 x 10(-6) g x mL(-1). The detection limit of the proposed method is 6 x 10(-9) g x mL(-1) and the RSD is 1.6% (n = 11) at 2 x 10(-7) g x mL(-1). This result is satisfactory compared with the method mentioned in the pharmacopoeia of People's Republic of China.
