摘要
Ninhydrin was found to exhibit chemiluminescence (CL) when it was oxidized with hydrogen peroxide in neutral or weakly acidic solution. Copper(II) and Co-II can catalyse the CL reaction, on the basis of which ppb levels of Cu-II and Co-II can be determined. In the presence of Cu-II, some amino acids enhanced the CL reaction, whereas others inhibited the CL reaction in the presence of Co-II. A flow-injection system with CL detection was developed for the determination of some amino acids. The mechanism of the CL reaction is discussed.
