Chemiluminescence Analysis of Xanthinol Nicotinate in Reversed Micelle Media
Abstract:
Under acidic condition,the nitrogen in xanthinol nicotinate was protonated followed by its reaction with Cl4- anion to form an ion-complex,which was carried into a reversed micelle of cetyltrimethyla-mmonium chlorine containing luminol by chloroform,and the dissociated Cl4- reacted with luminol to produce an analytical chemiluminescence signal.In a certain concetration range,the CL intensity was proportional to the concentration of xanthinol nicotinate.Under the optimum conditions,the linear range was 0.01 to 15×10-6 g/mL,and the limit of detection was 0.4×10-9 g/mL with a relative standard deviation(n=11) of ca.1.26% for xanthinol nicotinate of 1.0×10-6 g/mL.The method is simple,sensitive and has been applied to determining the studied drug in injection successfully.
