  1. For same mineral, desorption of 125i " on it was weaker than 125io3 ", and sorption of 125i i25io3 " on galenite is irreversible. apparent diffusion coefficient da of 125i " in the mixed material were determined by the pass - through diffusion way, da values under atmosphere was given : da = 7. 29x10 - 12m2 ? s - 1

    大氣條件下,隨體系固液比的減小,固相的量相對在下降, 125i -在礦物材料上的kd值減小;隨材料粒度的減小,材料的比表面積增加, 125i -在礦物材料上的kd值有所增加。
  2. In this paper, the performance of adsorbing and retarding 125i ( substituted for 129i ) for mixed materials as buffer, backfill material was investigated, the distribution coefficient kds by batch sorption experiments were determined for four kinds of minerals and one kind of bentonite under atmosphere, iodine sorption and desorption on several mianerals were studied under low oxygen ambience at first time in the domestic, and apparent diffusion coefficient da of 125i ~ was determined for mixed minerals under atmosphere
