基于卟啉传感器的三聚氰胺检测研究

In allusion to the drawback of the high cost and long time analysis of traditional melamine detection methods, a melamine detection system was designed based on the basic principle of color change between porphyrin chemical sensors and molecules or ions in liquid. Depending on the software and hardware systems, making a study of spectrum signal and pattern recognition, and obtaining the characteristics information of target substance, eventually to arrive the detection of target substances by matching recognition. According to the actual situation, using the detection device to make a experimental detection of melamine in milk, and come to a result that the system can achieve effective detection of melamine when the concentration of melamine is bellow 2ppm in milk, at the same time, the device gives a early warning when the concentration goes beyond 2ppm.
