| Abstract: |
| To fully understand the state-of-the-art and trends of solidification/stabilization(S/S)technology for the remediation of sites contaminated by heavy metals, literatures from the China National Knowledge Infrastructure(CNKI), China Academic Journals Full-text Database, and Web of Science Core Collection Database published from 2006 to 2018 were investigated. The collected documents were screened and sorted using Excel 2016, HistCite Pro 2.1, and Origin 9.0. Annually published papers, the country/region of origin, published journals, the top ten cited papers, the top ten research institutions, research content, remediation materials, and contaminants were all factors that were analyzed and compared. The following conclusions were drawn:The number of Chinese publications increased over the 13 studied years and significantly more studies were published in Chinese than in English. In addition, the number of English publications from Chinese authors and research institutions were more than those from other countries; however, the average total global citation score (TGCS/R)of them was relatively low. Among the top 10 most cited papers, only two were by Chinese authors. Furthermore, although much research was focused on combined remediation materials derived from biomass carbon, lime, zeolite, diatomite, etc., few led to the development of equipment and technical implementation processes. The most studied contaminants were found to be cadmium and lead. In the future, Chinese scholars should reference international research results more to improve the quality of their work and ensure it has greater influence. Additionally, advances should be made in technical processes, the treatment of equipment, and standardized post evaluation methods. |
