ADVANCE IN SYNTHESIS AND APPLICATION RESEARCH OF BORON ION EXCHANGE RESIN

This paper introduced the principle of extracting boron with resins.Research status and applications of various types of boron ion exchange resins were summarized,which were stated in terms of functional groups such as polyol,carbohydrate,vicinal-diphenol,as well as matrix materials included polystyrene,polyacrylate,inorganic-organic composite resins,natural polymers and so on.Advantages and disadvantages of these resins were discussed.The paper argues that N-Methyl-D-glucamine works best as the functional reagent.However,each matrix material has its own costs and benefits.A summary of recent information on applications of the boron-specific resins in water treatment and environmental protection,extraction and separation of boron,analysis of boron were provided.The designing trend of novel boron resins were prospected.
