英文摘要	Resonance rayleigh scattering (rrs) has been explored as a detection (rrsd) technique for capillary electrophoresis (ce) or flow injection analysis (fia) of inorganic ions. the detection was achieved through a scattering probe of ion-association complex formed from rhodamine b (rh b) and iodine. the probe scatters strongly at 630 nm when oxidants such as cr2o72-, mno4- and clo- present in a mixed solution of rh b and iodide. the scattering disappears once iodine is reduced by reductants. oxidant or reductant species in a sample can thus be detected by positive or negative rrs signal. to verify the rrsd, fia-rrsd was first constructed and continuous measurement of testing samples containing cr2o72-, mno4- and/or clo- was performed. the detection limits reached a level of decade nm and a linear range was found between peak height and concentration at the range of 0.255-2.04 mu m for cr2o72-, 0.158-3.16 mu m for mno4-, and 1.18-9.43 mu m for clo-, with linear regression coefficients of all above 0.99. the run-to-run relative standard deviation of peak height was less than 3% (n = 6). ce-rrsd was then set up and studied, using a capillary of 75 mu m i.d. x 33 cm filled with a running buffer of 50 mm citrate and 25 mm tris (ph 3.32) and worked under -12 kv at room temperature. the ce eluent was at-line conducted into a stream of rhodamine b and iodine flowing inner a wide tube by plugging the capillary outlet into the wide tube. different mixtures prepared from cr2o72-, mno4- and clo- were successfully separated and detected by the ce-rrsd.
