1 引言 动力学分析法测定痕量锰已有很多报道,本文首次详细考察了茜素S-Mn(Ⅱ)-2,2′-联吡啶-H_2O_2体系的动力学行为,探讨了反应机理,确定了反应的最佳条件,用于痕量锰的测定有较高的灵敏度和较好的选择性。
1 Introduction Kinetic analysis of trace amounts of manganese has been reported for the first time. In this paper, the kinetic behavior of alizarin S-Mn (Ⅱ) -2,2’-bipyridyl-H 2 O 2 system has been investigated in detail for the first time. The reaction mechanism was discussed, The best reaction conditions for the determination of trace manganese with higher sensitivity and better selectivity.
