Several passive biosorption mechanisms of uranium such as complexation,redox,microprecipitation and ion exchange are discussed,and the trend of development is forecasted.
Certified reference material of the high-purity silicasol was prepared by removing impurity ions from the high purity silicasol according to the ion exchange resin.
The method of synthesising terpinol with ion exchange resin catalysis was investigated. Effects of kind of solvent used, reaction temperature and reaction time on product output were studied.
