Abstract
Objective: Objective: attapulgite, as a kind of natural adsorption material with abundant reserves and friendly environment, has been widely concerned by mineral, environment, materials, chemistry and other disciplines.CiteSpace software was used to analyze the literatures about attapulgite adsorption application from 1987 to 2021 in CNKI database. Results: the amount of literature about attapulgite adsorption application showed an increasing trend year by year; The key words were: modification, kinetics, etc.; The core authors were: Shuang Ren, Mengfei Zhang, Bin Shuai etc.; The organization with the largest number of papers was the northwest Key Laboratory of plant nutrition and agricultural environment, Ministry of agriculture. Conclusion: this paper deeply analyzes the development status and current hot spots of attapulgite in the field of adsorption application research, and forecasts the future development trend, in order to promote the efficient utilization of attapulgite and provide reference for the next research.
Highlights
Attapulgite belongs to the sepiolite group of 2: l ayered silicate minerals[1]
Using the software CiteSpace (5.6.R4) to visually analyze the related literature and draw the corresponding knowledge map, which can truly reflect the relationship between the research and development process and the knowledge structure system [3]
The development of attapulgite in the adsorption application field is analyzed in depth
Summary
Attapulgite belongs to the sepiolite group of 2: l ayered silicate minerals[1]. With its superior adsorption performance, wide resource distribution and low price, it is widely used in various fields. With the rapid development of information technology, new technology and new theory have been injected into the discipline research field, and the research object, research method and research content of archival science have changed. By drawing the knowledge map of a discipline, we can visually present the research status of a discipline and track the research hotspots in the discipline [2]
