Insights into the development of electrokinetic remediation technology: A bibliometric analysis

Electrokinetic remediation (EKR) is a powerful technique aimed at pollutant removal in soil, sludge, mine tailings, and so on. In the current work, we performed bibliometric analysis of research on EKR for period 1900–2018 basis core database Science Citation Index Expanded. addition to basic characteristics, keywords were analysed four major participants: USA, China, Spain, South Korea. The periods 1990–2001, 2002–2008, 2009–2018 studied using keyword method gain insights into development predict its future trends. results revealed that related field USA was broad during study periods. Meanwhile, China interested fluorine pollution contamination red soil. Spain paid close attention due agricultural contamination. Korea focused radioactive element pollution. number papers published over 28 years increased steadily continued rise after 2008. combined techniques + phytoremediation bioremediation successively utilised by scholars time, latter expected demonstrate vitality future.
