Progress of Dissolved Organic Matter in Inland Water by Three-Dimensional Fluorescence Spectroscopy Based on CiteSpace
Bibliometric methods were used to sort out the current status,hotspots and development trends of research on dissolved organic matter(DOM)in inland waters by three-dimensional fluorescence spectroscopy at home and abroad.Using CiteSpace knowledge graph analysis tool and CNKI and WoS core collection as data sources,the annual publication volume,authors and countries,keyword clustering and highlighting were visualized and analyzed,and the data analysis methods and analytical teehniques of DOM and 3D fluorescence spectroscopy in inland water were reviewed.The results show that the annual publication volume of this field is on the rise and is mainly characterized by the rapid growth of foreign language literature,China is the country with the largest publication volume,the degree of international exchange and cooperation is high and a stable research group has been formed,and the research potential is sufficient.Domestic and international research on dissolved organic matter in inland waters using three-dimensional fluorescence spectroscopy is mainly focused on waters susceptible to human activities or serious eutrophication,including dissolved organic matter in eutrophic waters and sediments,colored dissolved organic matter and disinfection by-products,as well as dissolved organic matter-heavy metal interactions,global climate change response,bioavailability,etc.In addition to conventional data analysis methods,the comprehensive use of three-dimensional fluorescence spectroscopy combined with absorption spectroscopy,mass spectrometry and other techniques to analyze the composition and source characteristics of dissolved organic matter in inland waters at the molecular level is an important research hot spot and trend in this field in the future.
