| Abstract: | This paper reports a new complex chemiluminescence, i. e. luminol-IO4-catalyzed by Co(1, 10-phen·)32+ complex. Based on this catalyst a new chemiluminescence method for determining trace of Co(Ⅱ) is proposed. The detection limit is 8×10-8g/L Co(Ⅱ),the linear dynamic range is 1×10-6~1×10-4g/L Co(Ⅱ) and the variation coeffient at a cobalt concentration of 1×10-4g/L Co(Ⅱ) is 2.5%(n=10). This method has been satisfactorily applied in the determination of trace cobalt ion in VITAMIN B12 samples. |
| Keywords: | complex chemiluminescence luminol Co 1 10-phenanthroline |
