| Abstract: |
| Bibliometrics was used to quantitatively analyze literatures about the remediation of chromium-contaminated soil during the last 15 years based on the Web of Science database. The development and change in the remediation technologies of chromium-contaminated soil in the different stages(years 2001-2005, 2006-2010 and 2011-2015) were investigated to compare the similarities and differences in the remediation technologies in the different stages. The results indicated that the application feasibility of electrokinetic remediation and bioremediation are dominated at the initial stage, and then topics transferred to soil washing remediation, passivation or reduction remediation and bioremediation with the concentration on the screening bioremediation strain and phytoremediation. Nowadays, the remediation technologies come to combined remediation with several technologies, exploration of new techniques and materials, indicating the enhancement of interdisciplinary. The studies on the remediation of chromium-contaminated soil developed more and more thoroughly and widespreadly, the driving force for which was the optimization of material function and environmentally-friendly materials and technologies. After decades of development, the focus in the next stage would be the application of new nano and loading-form materials. The challenge for the remediation would be the difficulties in integration and regional adaptation of remediation technologies. |
