"Flow Injection-chemiluminescence System For Reduced Coenzyme I With Immobilized Reagents"
Shaanxi Shifan Daxue Xuebao (Ziran Kexue Ban) 1998 Volume 26, Issue 4 Pages 74-76

Abstract: A novel chemiluminescence (CL)-based system for reduced coenzyme I (NADH) combined with flow injection analysis is presented. The anal. reagents, luminol and Fe3+are immobilized on an anion exchange resin column and a cation exchange resin column, respectively. Fe3+is eluted by HCl solution passing through the cation exchange column and mixes and reacts with the sample stream to generate Fe2+, which then merges with the luminol stream eluted by the injection of sodium phosphate through the anion exchange column under alkaline conditions to produce CL. The CL emission intensity is correlated with the standard NADH concentration. in the range 1 x 10^-7 to 1 x 10^-4 mol/L, and the detection limit is 5.5 x 10^-8 mol/L. A complete anal. including sampling and washing could be performed in 1 min. The system is stable for 200 times with a relative standard deviation of less than 5%.

"Determination Of Analgin By Flow Injection Analysis With Chemiluminescence Detection"
Shaanxi Shifan Daxue Xuebao (Ziran Kexue Ban) 1998 Volume 26, Issue 3 Pages 68-70

Abstract: A new method for the determination of analgin in tablets and injections by using flow injection chemiluminescence was based on the chemiluminescence reaction of analgin-KMnO4. The main factors which affect the determination were investigated. Under optimum conditions, the linear range for the determination of analgin was 1 x 10^-7-8 x 10^-5g/mL, the determination limit was 4.2 x 10^-8 g/mL.

Abstract: A flow injection catalytic spectrophotometry is described for the simultaneous determination of iron(III) and vanadium(V). It is based on the different catalytic behavior of iron(III) and vanadium(V) to decoloration reaction between potassium bromate and victoria blue B in different media and chemometric method CPA matrix is employed. This method has been applied to determination of iron(III) and vanadium(V) binary mixture in the range of 1:2~40:1 (concentration. ratio) with average recoveries of 95.5% and 103.5%, respectively. for iron(III) and vanadium(V).

"Flow Injection Chemiluminescence Analysis Of Alkaloids"
Shaanxi Shifan Daxue Xuebao (Ziran Kexue Ban) 1998 Volume 26, Issue 1 Pages 63-65

Abstract: The ppt. of alkaloids with NH4[Cr(NH3)2(SCN)4].cntdot.H2O is found to catalyze the chemiluminescence reaction of H2O2-luminol. Alkaloids can decrease the chemiluminescence intensity of H2O2-luminol-NH4[Cr(NH3)2(SCN)4].cntdot.H2O because of precipitation The magnitude of decrease is linear with the concentration. of alkaloids. A flow injection chemiluminescence anal. method for a number of alkaloids is established based on this observation.
