A novel sensing system has been designed for cobalt ion detection based on a cobalt ion improved chemiluminescence (CL) in N-bromosuccinimide(NBS)-reduced carbon quantum dot (rCD) (OH−) system. The mechanism of this CL analysis system has been preliminarily studied. In this work, it was demonstrated that this facile methodology offers rapid, sensitive and reliable detection for cobalt ions with a detection limit as low as 3.252 × 10− 6 mol/L and a linearity range from 1.004 × 10− 5 to 1.004 × 10− 3 mol/L (r = 0.9990), which has promising application prospects.
