Abstract: Soil leaching, known as a new efficient soil remediation technology, has obtained rapid development in recent years. Focusing on the field of remediation of heavy metal contaminated soil using leaching technology, relevant publications and patents were analyzed with the method of bibliometric analysis. Then on this basis, the annual trends both at home and abroad were overviewed systematically, the distribution of major research institutions, regions and countries contributing to the papers and patents analyzed, and the gap between China and the major developed countries and regions in the world discussed. In the end, it was pointed that the key technologies and hotspots in this field are the leaching process and equipment and eluting reagent.
