| Abstract: | Research and application progress about chelating extraction of metal ions by supercritical CO2 fluid technology was reviewed. Principle, method and kinetics of supercritical chelating extraction, choice of chelating agents and modifiers, factors affecting the extraction, such as pressure, temperature, time and pH were discussed. The application of supercritical CO2 fluid technology on the environmental protection, nuclear industry, metal industry, chemical analysis, Chinese traditional medicine industry, health food industry were introduced. Finally, several problems about supercritical chelating extraction have been discussed and the future development directions have also been suggested. |
