| Abstract: | A sensitive flow injection chemiluminescence（FL-CI.） method for determination of thiosemicarbazide was developed. The method was based on that thiosemicarbazide could enhance the CL reaction of glyoxal and KMnO4 in hydrochloric acid. Under the optimized conditions, thiosemicarbazide was determined, the detection limit of the method was 5. 0 X 10-8mol· L^-1 for thiosemicarbazide, the linear range for thioscmicarbazide was 1.0 × 10^-7-1.0 ×10^-8mol.L^-1,and the relative standard deviation was 2. 1% for 1.0 × 10^-6mol.L^-1 thiosemicarbazide in 11 repeated measurements. The method is successfully applied for the determination of thiosemicarbazide in water sample. |
