title: [Terbium sensitized chemiluminescence of enoxacin].
abstract: OBJECTIVE
  To determine the enoxacin by means of terbium sensitized chemiluminescence in pharmaceutical preparations as well as urine samples.
  
  
  METHODS
  Through six-way injection valve Ce4+, H2SO3, Tb3+ and enoxacin (ENX) standard solutions were injected into the flow system in a certain order, the chemiluminescence signal was detected by weak luminescence analyzer.
  
  
  RESULTS
  The chemiluminescence intensity was linearly related to the concentration of ENX in the range of 2.0 x 10(-9)-6.0 x 10(-8) mol.L-1 with a detection limit of 4.0 x 10(-10) mol.L-1. Relative standard deviation was less than 1.6% (n = 11).
  
  
  CONCLUSIONS
  It provides a sensitive rapid, simple and accuracy measurement of enoxacin for the pharmacokinetic studies.
