Vol. 27, nr 2

28--40

Epoxy resin (EP) has been widely used in many fields due to its excellent physical and chemical properties. However, its inherent flammability limits its application in some fields, and the development of efficient and environmentally friendly new flame retardants has become a research hotspot. In recent years, researchers have been committed to developing new flame retardants to improve the flame retardant properties of EP. The development of synergistic flame retardant systems, combined with the advantages of various flame retardants, has become a research trend. In this paper, the application progress of three kinds of new flame retardants in EP, including nano-materials, organic materials, and inorganic materials, is summarized. Their synthesis methods, structural design, and application prospects are compared, and a summary and prospect are given.

Acid mine drainage has always been of global concern, primarily due to its low pH, high concentration of heavy metals and toxic substances, and serious impact on the surrounding environment and ecology of mines. However, the research progress and hotspots in this field of acid mine drainage processing are still unclear. To better understand the research hotspots and trends of acid mine drainage processing from 2004 to 2023, we used CiteSpace bibliometric software to visually analyze 1142 English-language research articles and reviews from the Web of Science core database. Results indicated that this field has received increas-ing attention from researchers worldwide, especially since 2017. The USA and China stand out as major contributors, yet their international collaboration doesn't match South Africa robust partnerships. Strengthening cooperation with other nations should be a priority for both the USA and China. The University of Quebec and University of South Africa were the most production institution. Vhahangwele Masindi from South Africa was the most active author. The top two core journals in this field were Science of the Total Environment and Water Research. Additionally, through keyword cooccurrence, clustering, and burst analysis, it is evident that research on heavy metal mechanisms and resource recovery will be the future research hotspots in this field of acid mine drainage. This study provides researchers with an opportunity to understand the hotspots and trends in acid mine drainage research from a bibliometric perspective, and serves as a reference for future studies.
