摘要：
A flow injection procedure for the determination of calf thymus DNA (CT DNA) over the range 2.1x10(-6)similar to2.1x10(-1) mug mL(-1) is described, based on measurement of the enhanced chemiluminescence emission of rhodamine B-Ce(W) system, activated by imidazole-HCl buffer solution. This method is highly sensitive, with the linearity range broadened to five orders of magnitude. It has been applied to determine CT DNA in synthetic sample with satisfactory results.
