Evaluation of the Adsorption Capacity of Banana Peel in the Removal of Emerging Contaminants present in Aqueous Media – Study based on Factorial Design

Abstract

A simple procedure was developed with the adsorption of the compounds estrone (E1), 17α-ethinylestradiol (EE2), and sulfamethoxazole (SMX) in aqueous solutions using banana peel as an adsorbent material. Adsorbent mass, contact time, and granulometry were studied through multivariate design. The proposed adsorbent was advantageous, with removal exceeding 80% for E1 and EE2 and 70% for SMX in the analysed samples. Studies of adsorption isotherms demonstrate adequacy compared to the Freundlich model, and kinetic studies indicate adsorption through the pseudosecond order model (E1 = 0.9999, EE2 = 0.9999, and SMX = 0.9999). The developed method was successfully applied in supply water samples and accuracy was evaluated through recovery tests, with recovery ranging from 70% to 96%.

Banana Peel Powder Biosorbent for Removal of Hazardous Organic Pollutants from Wastewater

“…Therefore, reusing this material to remove organic pollutants from contaminated water is a process of high commercial interest. The use of dried banana peel powder (BPP) as a biosorbent material has been explored for the decontamination of wastewater, mainly in the removal of textile dyes [ 17 , 18 , 19 , 20 ], heavy metals [ 21 , 22 , 23 ], crude oil [ 24 ], phenolic compounds [ 25 ], pharmaceuticals [ 26 , 27 ], and pesticides [ 27 , 28 , 29 ], as has been well documented in two relatively recent reviews [ 16 , 30 ]. Most studies reporting banana peel-based biosorbents have shown efficient biosorbent reuse up to five cycles and above [ 16 , 31 ].…”

Adsorptive capture of Congo red and Erythromycin pollutants from water by Functionalized ecofriendly chitosan and nanobiochar with silica gel

“…Accordingly, appropriate research on the usage of natural banana peels in water decontamination will be bene cial in terms of commercial applications due to the extensive availability and e ciency of banana peels. Therefore, the application of banana peels is increasingly being used as cost-effective waste material for water puri cation from pharmaceuticals [32] and dyes [33]. In addition, the removal of CRD and methyl red dyes from aqueous solutions was investigated and reported by using the batch system.…”
