Paper Abstract

The fluorescence spectra of melamine-contained milk solution excited by the exciting light have been experimentally studied in this paper. The experiments show that the melamine-contained milk solution can produce strong fluorescence when excited by 467nm exciting light. The fluorescence spectrum peak is around 540nm and the fluorescence intensity would increase firstly and then decrease with the increasing concentration of melamine in pure milk. Based on this result, combining with the optical technology and computer technology, a simple detection system device has been designed. The device can quickly detect whether the milk containing melamine in real-time and accurately show the concentration of melamine in a certain range, which make the device have strong practicability.
