Research Progress and Hot Spots of Bisphenol Compounds Removal Technologies in Global Perspective: A Bibliometric Analysis from 1994 to 2023

Bisphenol compounds (BPs), widely utilized in industrial production, have raised significant concerns within the scientific community due to their high environmental risks, which pose serious threats to human health and ecological security. Consequently, numerous researchers have dedicated efforts to developing advanced technologies to address BPs pollution. In this study, bibliometric analysis was employed to visually analyze 13,639 publications related to BPs removal from 1994 to 2023, aiming to elucidate the development status, research hotspots, and frontier trends in BPs removal technologies. The consistent upward trend in annual publication numbers underscores the ongoing expansion and deepening of research in this field, with the Chinese Academy of Sciences emerging as the most prominent contributing institution. Keywords burst analysis revealed that advanced oxidative degradation has become a predominant research focus among BPs removal technologies (removal efficiency ranging between 80 and 100). It is anticipated that future research on BPs removal will likely concentrate on developing more efficient and cleaner technologies, emphasizing sustainability and environmental friendliness. Overall, this study offers an objective and comprehensive overview of the research landscape in BPs removal technologies, providing a valuable reference and insightful suggestions for future researchers in the field.
