I have synthesized some microporous ionic covalent organic frameworks, I collected their CO2 adsorption data at 273K, in order to calculate its QST, I wanna get some suggestions from the researchers in this field, that at what other temperatures I should analyze the CO2 adsorption in order to calculate QST? As well as please suggest me the amount of SO2 which is best to use for a breakthrough SO2 adsorption? As I already used up to 40mg sample for SO2 breakthrough experiment, is there any effect of the sample amount on SO2 breakthrough adsorption by microporous materials?
