The sample was activated at 150 oC for 12h
with dynamic vacuum before each measurement.The activated
sample weight was measured after experiment and was
used to calculate the SO2 adsorption results.The activated
sample weight for Ni(bdc)(ted)0.5,Zn(bdc)(ted)0.5 and Mg-
MOF-74 are 75.5 mg,94.2 mg and 95.6 mg respectively.The
activated sample was sealed in chamber B under vacuum.SO2(the total impurity of SO2 gas is less than 0.1% and the water
concentration is less than 0.01%) was introduced into chamber
A and then the valve connecting chamber A and B was opened
to let the gas adsorption reach equilibrium.This step was
repeated as necessary to obtain the adsorption data points.As
for the desorption part,a similar but reverse procedure was
adopted.The chamber A was evacuated (1×10 -4 Torr) and
then the valve connecting chamber A and B was opened to let
the gas desorption reach equilibrium.This step was also repeated
as n

答案

每次测量之前,将该样品加温至150℃激活,维持12小时动力真空状态.实验结束后测量被激活样品的重量,并使用该样品计算出二氧化硫的吸收量.被激活的样品重量为：Ni(bdc)(ted)0.5, Zn(bdc)(ted)0.5,Mg-MOF-74 分别为75.5 mg, 94.2 mg ,95.6 mg.将被激活的样品封装在真空B箱中.将二氧化硫（二氧化硫气体的杂质总量不超过0.1%,水的密度不超过0.01%）放入A箱,然后将接通A箱和B箱的阀门打开,使气体吸收量达到平衡.为了获得气体吸收数据点,必要时可以重复这一步骤.
