The dynamic analysis of this activation process is presented on the basis of langmuir isotherm model 在langmuir等溫吸附模型基礎(chǔ)上,對(duì)激活數(shù)據(jù)進(jìn)行了動(dòng)力學(xué)分析。
The adsorption isotherm of neptunium on silica gel correspond to the form of langmuir isotherm . according to clausius - claperon equation , from the slope in inkd vs 1 / t plot , adsorption heat could be estimated . from the data of adsorption heat it is concluded that the adsorption of neptunium on silica gel in nitric acid solutions belongs to chemical adsorption and the adsorption process is an endothermic reaction 三種價(jià)態(tài)的镎在硅膠上吸附的等溫線符合蘭格繆爾吸附等溫線的形式,是單分子層吸附;根據(jù)克勞修斯-克拉柏龍方程,以1nkd對(duì)1 t作圖,通過(guò)直線斜率計(jì)算出吸附熱,從吸附熱的數(shù)據(jù)可判斷三種價(jià)態(tài)的镎在硅膠上的吸附屬于化學(xué)吸附,是吸熱的過(guò)程;對(duì)npov ) 、 np ( v )和np ( vd在硅膠上的吸附進(jìn)行了比較,提出了三種價(jià)態(tài)的鋒在硅膠上吸附的機(jī)理。
