Research progress in rapid detection methods of lead in biomaterials
In the laboratory,we commonly used spectrophotometry,atomic absorption spectrometry,atomic fluorescence method,gas chromatography,high performance liquid chromatography,biosensor method to determine the content of lead in biological materials.Most of these methods were cumbersome to operate and their testing cycle was long,some methods had unstable operating conditions and high experimental requirements,it was difficult to meet the needs of emergency detection work.The rapid detection method had the characteristics of simple operation,rapid operation and portable instrument,and was suitable for the initial screening of suspected lead poisoning personnel and the emergency response of pollution sites.
