1969 graduated from Huazhong normal university, majoring in analytical chemistry. Has been engaged in the teaching and research of analytical chemistry. Lectures include advanced analysis, application of organic reagents in analytical chemistry, enrichment and separation. Mainly engaged in the separation and spectrophotometric determination of metal ions. He presided over the natural science foundation project of the Institute of Membrane Extraction Enrichment and Separation of Trace Components. Since 90 years ago, the enrichment and separation of trace analysis have always involved the extraction and purification of biological analysis. In the affinity extraction system formed by modifying polymers with dyes and chelating agents, a series of selective enrichment and separation of metal ions were carried out, followed by the separation and extraction of bioengineered products. Due to work innovation, 1995 won the second prize of scientific and technological progress of the State Ethnic Affairs Commission. Published 32 academic papers.
