From my work with zeolite 5A , I have learned that it is important to input gas in small units
(particularly with this zeolite) because essential information that is contained in the beginning behavior of
isotherm curves will be lost otherwise. Some possible sources of error in this particular experiment with
5A were that the sample was not kept sealed before hand in order to be isolated from moisture in the air
(which zeolites will readily adsorb), and also that in the soldering process some chemical flux may have

been introduce inside the zeolite chamber. My efforts to redeem the sample consisted of vacuuming out
the chamber while heating the zeolite chamber to a temperature that would adequately boil off any
adsorbed moisture. I believe that this method sufficiently purified the sample.
Because of the ease with which zeolites adsorb moisture, a suggestion for future research is to
purify the zeolite as much as possible before experimentation, either by dessication (in case of water
adsorption), or by heating the sealed zeolite chamber to evaporate any moisture trapped within the
molecular cages, as was performed in this study.
