通过长期实验研究了三种活性炭对17 β-雌二醇的吸附特性，以确定固液平衡所需的时间。通过液体闪烁计数，使用放射性标记的17 β-雌二醇在ppt范围内的不同浓度下测量吸附动力学。17 β-雌二醇被迅速吸附，50-180分钟后达到接近平衡的条件。在1 - 100 ng/l的浓度范围内，平衡浓度计算为初始浓度的49-81%，1 ng/l的初始浓度为0.51 ng/l，100 ng/l的初始浓度为5.9 - 14.6 ng/l。(C)2001爱思唯尔科技有限公司版权所有。
The adsorption characteristics of three types of activated carbon for 17 beta -estradiol were studied by long term experiments to assess the time which is necessary to reach equilibrium between the solid and the liquid phase. The adsorption kinetics were measured by liquid scintillation counting using radio-labelled 17 beta -estradiol at various concentrations of 17 beta -estradiol in the ppt range. 17 beta -estradiol is quickly adsorbed and conditions close to equilibrium were reached after 50-180 min. The equilibrium concentrations were calculated to be at 49-81% of the initial concentration in the concentration range between 1 and 100 ng/l, with 0.51 ng/l for a I ng/l and between 5.9 and 14.6 ng/l for 100 ng/l initial concentration.
