METHOD OF PREPARING SORBENTS Russian patent published in 1996 - IPC

FIELD: preparation of solid-phase sorbents, in particular, for biospecific processes. SUBSTANCE: solid-phase nonporous materials including those containing no reactive functional groups, for example, metals, glass, ceramics, and plastics, are proposed to be used as carriers. Activation of carrier is accomplished in vapors of activating agents under reduced pressure (0.49-0.98 Pa) in ultra-high frequency field with power 15-30 W for 0.5-2.5 min. As activation agents, glutaric, salicylic or benzoic aldehydes are used. EFFECT: enhanced efficiency of process. 3 cl, 3 dwg
