Description
In this research, the effect of surface modifiers derived from waste on the ammonia adsorption of physically activated bagasse fly ash was investigated. BFA was mixed with 15% w/w of bamboo hydrochar or red mud followed by steam activation. BFA was combined with 15% w/w of either bamboo hydrochar or red mud, followed by steam activation. The research analyzed the adsorption capacity and surface characteristics of BFA. The findings indicated that both surface modifiers led to a decrease in the BET surface area and porosity of BFA, indicating successful positioning of the modifiers. However, this resulted in an enhancement of their capacity to adsorb ammonia. Notably, physically activated BFA mixed with bamboo hydrochar exhibited the highest performance, achieving a capacity of 0.885 mL-NH3/g-adsorbent. This investigation offers insights into optimizing BFA as an adsorbent for ammonia and contributes to the advancement of sustainable and cost-effective adsorption technologies.
