| Abstract: | A novel chemiluminescence sensor is designed for monitoring sodium in serum. Based on chemiluminescence reaction between luminol, iron(II) and oxygen coupling ion regenerated reaction, the determination of sodium can be completed indirectly. The linear range of calibration curve of sodium is 5×10-7～1×10-5mol*dm-3, and the detection limit is 2×10-7mol*dm-3. The relative standard deviation is 2.9% （5×10-6mol*dm-3 sodium，n = 11）. Efficiency of sample analysis is 120 times per hour,sensor service life can last for 3 days. |
