Flow Injection Chemiluminescence

A flow injection chemiluminescence (CL) method has been developed for the determination of indoleacetic acid (IAA). It is based on the fact that the weak CL of Ce(IV)-Ru(phen)32+ system is strongly enhanced in the presence of silver nanoparticles. Optimum conditions and possible mechanisms have been investigated. Under optimum experimental conditions, the linear range is from 1.0×10-8 – 6.0×10-7 g mL-1 with a detection limit 9.0×10-9 g mL-1

A simple, sensitive and rapid method for flow injection with chemiluminescence analysis has been developed for the determination of prednisone acetate at trace level. This method is based on the luminescent properties of the tris(1,10-phenanthroline) ruthenium(II)-potassium permanganate -prednisone acetate in acidic medium sensitized by Na2SO3. The optimized experimental conditions are evaluated. Under the optimum experimental conditions, the linear ranges of prednisone acetate are: 4.0×10-10~4.0×10-8g·mL-1and 4.0×10-8~2.0×10-7g·mL-1with a low detection limit is 4.5×10-11g·mL-1and the relative standard deviation for 1.0×10-8g·mL-1sample is 1.04% (n=11). The proposed method has been successfully applied to the determination of prednisone acetate in tablets.

Flow Injection Chemiluminescence

It is found thatManganese Deuteroporphyrin (Mn(Ⅲ)DP) can greatly enhance the chemiluminescence intensity of luminol-hydrogen peroxide system in alkaline conditions. Basing on that fact a flow injection chemiluminescence (CL) method has been developed for the determination of acetaminophen. With the peak height as a quantitative parameter applying optimum conditions, the relative CL intensity was linear with acetaminophen concentration in the range of 1.0×10-9～1.0×10-7 g/mL with a detection limit of 2.8×10-10 g/mL. The relative standard deviation (RSD) was 2.7% for 2.0 x10-8 g/mL acetaminophen (n = 11). The proposed method held low detection limit and was successfully applied to determination of acetaminophen in pharmaceutical preparations.

Flow Injection Chemiluminescence

A new flow injection chemiluminescence (CL) method for the determination of Enoxacin（ENX）was described. The method was based on the weak CL reaction of Ce(Ⅳ)-SO32- sensitized by Pr3+- ENX. The relative CL intensity was linear with the concentration of ENX in the range of 3×10-8 g•mL-1~5.0×10-7 g•mL-1. The detection limit is 1.0×10-8 g•mL-1 .The rSuperscript textelative standard deviation (RSD) for the determination of 4.0×10-7 g•mL-1 ENX is 3.5% (n=11). The method has been successfully applied to the analysis of ENX in tablet
