Monodisperse boron-selective resins

摘要

Macroporous, monodisperse ion exchanger comprises N-methylglucamine-structures and exhibits an average diameter of 550-750 mu m and a volume portion of 75% pearl of 0.9-1.1 D, and the monodispersion is obtained by filtering heterodisperser resins, by atomizing method or seed/feed method. An independent claim is included for a process for selective adsorption of boron using the ion exchanger.
