考马斯亮蓝Ｇ是一种生物染色剂 ,在分析测定中多用于蛋白质的测定[1 ,2 ] 。近年也有人用此试剂做催化动力学分析中的指示剂[3 ,4] 。我们在研究中发现 ,考马斯亮蓝Ｇ用于缔合物体系测定阳离子 ,有较好的结果。本文研究了以铜离子为催化剂 ,在抗坏血酸存在下的钼 硫氰酸盐 考马 Coomassie Brilliant Blue G is a biological stain used in the determination of protein in the assay [1, 2]. In recent years, some people use this reagent as an indicator in catalytic kinetic analysis [3, 4]. We have found in the study that Coomassie Brilliant Blue G has good results for the determination of cations in association systems. In this paper, copper ion as a catalyst in the presence of ascorbic acid molybdenum thiocyanate test horse
