TL;DR: In this paper, the effect of CO2 on the adsorption of activated carbon under room temprature and a controlled nuetral pH was investigated for two identical sets of bottles with the expectation that CO2 was purged in one of them to insure its dominance over other gases in solution.
Abstract: Adsorption isotherms studies were performed for phenol and o‐cresol to study the effect of CO2 on their adsorption on activated carbon under room temprature and controlled nuetral pH. Standard bottle‐point technique was used for two identical sets of bottles with the exeption that CO2 was purged in one of them to insure its dominance over the other gases in solution. It was observed that CO2 rcduceced the adsorptive capacity of activated carbon for both phenol and o‐crcsol significanyly. However, the effect on o‐crcsol adsorption was higher than that on phenol. Analysis of variance tables were constructed, F test was used to test the null hypothesis, and the results were statisticaly significant.
