Banana Peel as an Adsorbent for Removing Atrazine and Ametryne from Waters

Abstract

The feasibility of using banana peel for removal of the pesticides atrazine and ametryne from river and treated waters has been demonstrated, allowing the design of an efficient, fast, and low-cost strategy for remediation of polluted waters. The conditions for removal of these pesticides in a laboratory scale were optimized as sample volume = 50 mL, banana mass = 3.0 g, stirring time = 40 min, and no pH adjustment necessary. KF(sor) values for atrazine and ametryne were evaluated as 35.8 and 54.1 μg g(-1) (μL mL(-1)) by using liquid scintillation spectrometry. Adsorption was also evaluated by LC-ESI-MS/MS. As quantification limits were 0.10 and 0.14 μg L(-1) for both pesticides, sample preconcentration was not needed. Linear analytical curves (up to 10 μg L(-1)), precise results (RSD < 4.5%), good recoveries (82.9-106.6%), and a > 90% removal efficiency were attained for both pesticides. Water samples collected near an intensively cultivated area were adequately remedied.

Agricultural waste peels as versatile biomass for water purification – A review

“…Banana peel is the main residue, corresponding to 30-40% (w/w), and has been mainly used in composting, animal feeding, and the production of proteins, ethanol, methane, pectin, and enzymes [76].…”

“…The BET surface area of OPP, MNP and MNP-OPP was found to be 47.03,76.32 and 65.19 m 2 g −1 respectively. Authors pointed out that although MNP-OPP had a lower surface area than MNP, its adsorption capacity was higher which indicates that the multiplefunctional groups on MNP-OPP played an important role in the enhancement of the adsorption capacity.…”

“…Equilibrium data fitted well to the Langmuir and Redlich-Peterson models with a maximum adsorption capacity of 14 mg/g. The feasibility of using banana peel for removal of the pesticides atrazine and ametryne from river and treated waters has been demonstrated[76]. The conditions for removal of these pesticides in a laboratory scale were optimized as sample volume = 50 mL, banana mass = 3.0 g, stirring time = 40 min, and no pH adjustment necessary.…”

Fruit peel waste as a novel low-cost bio adsorbent

“…Some other organic pollutants such as palm oil mill effluent (Mohammed and Chong 2014), pesticides (Silva et al 2013), some phenolic compounds (Agarry et al 2013, Edison andSethuraman 2013), and inorganic pollutants like oil/grease particles (El-Nafaty et al 2013, Borhan et al 2014, lubricating oil, and diesel (Zou et al 2014) have been removed by using FPW.…”

Sorption, kinetics and thermodynamics studies of atrazine herbicide removal from water using iron nano-composite material

“…In view of these facts, it was considered worthwhile to develop fast, effective, economic and reproducible method for the subtraction of atrazine from water. The literature shows some adsorption methods for the removal of atrazine (Gai et al 2011;Zhang et al 2011;Chaparadza and Hossenlopp 2012;Báez et al 2013;Silva et al 2013;Zhao et al 2013;Yola et al 2014;Gupta et al 2015). It was observed that some methods work at extreme pHs, which are not suitable to work under natural water conditions.…”
