[Flow injection analysis of ciprofloxacin by terbium sensitized chemiluminescence method].

A new flow injection chemiluminescence (CL) method for the determination of Ciprofloxacin (CPLX) was described. The method was based on the weak CL reaction of Ce(IV)-SO3(2-) sensitized by Tb3+ -CPLX. The relative CL intensity was linear with the concentration of CPLX in the range of 9.

[Studies on photoluminescence characteristics of curcumin in acrylamide polymer].

A photoluminescence polymer was prepared using acrylamide as a monomer, a large excess of ethyleneglycol dimethacrylate as the cross-linking agent, and curcumin as a fluorescence additive. The polymer was ground into powder and screened in order to get even powder, whose diameter was from 40 to 75 microm. The emission spectra of curcumin in solid powder polymer show a strong blue shift compared with that of curcumin in C2H5OH solution.
