Abstract
The production of food for humans and animals, as well as industrial and agricultural processes, all depend increasingly on clean water. As a result of rapid industrialization, heavy metals including chromium are in our waterways. The goal of this study was to help with the search for less expensive water treatment methods, that is why Saba banana peels are used as biobsorbent. SBP has a rough structure with small openings and holes on its surface which increased the surface area and allowed pores to diffuse during the adsorption process. The adsorption experiment conducted reveals that the amount of chromium ions adsorbed is from 19666.67mg/L to 7966.67 mg/L, and as the initial iron concentration rises, so does the amount of adsorbed ions. Also, the uptake capacity of SBOP biosorbent is from 98.33mg/g to 398.17 mg/g, and it was observed that uptake capacity increases as the initial concentration of chromium increases. For the percentage of adsorption, in starts from 98.33% and stops at 99.59% after 48 hours of contact time . Which indicates that percentage of Cr (VI) removed from aqueous solution increases when the chromium concentration also increases when the chromium concentration also increases, it was concluded that SBP is a potential biosorbent for heavy metal like chroium which can be commonly found in wastewaters.
