Progress in Picric Acid Detection:Visual Analysis based on Citespace
Based on 123 literatures related to"picric acid detection"in CNKI database from 2008 to 2023,the development trend of picric acid detection in recent years was discussed by using CiteSpace software for data processing and visualization.Some new methods for the detection of picric acid are introduced,especially the fluorescence probe method.According to the quantitative analysis of literature and detailed analysis of a single paper,fluorescence quenching is a major development trend for the detection of picric acid,and the fluorescent probes that can be used to detect picric acid also show diversity.The reported fluorescent probes have high selectivity for picric acid,and the combination of different fluorescent probes can achieve more accurate qualitative and quantitative detection of picric acid.It is believed that with the development of fluorescent probes,this method has the potential to be developed into a standard method.
