“…The adsorption isotherm can explain the relationship between the adsorbate concentration and the adsorbate concentration remaining in the liquid at equilibrium time [28]. The adsorption isotherm can be determined by using the results of the adsorption process of AO by AMS at various concentrations.…”

Andisol has a large surface area, is mesoporous, and contains the active groups' silanol (Si-OH) and aluminol (Al-OH). Besides andisol, cellulose is a good adsorbent, because microcrystalline cellulose has an active hydroxyl group (OH). The number of active adsorbent groups can be enhanced by chemically modifying the surface area (increment), or adding other materials. These modifications included alkaline modified-andisol with the addition of NaOH to increase pore size, cellulose hydrolysis with HCl to increase surface area, and andisol modification with the inclusion of other materials, mainly cellulose, to increase surface area. After the adsorption process is complete, the adsorption capacity of andisol-microcrystalline cellulose (AMS) to auramine O (AO) is known. As an adsorbent for AO, the surface area of BET andisol is 25.92 m2/g and the pore diameter is 14.40 nm, while the surface area of microcrystalline cellulose and AMS adsorbent are 26.60 m2/g and 18.60 m2/g, respectively. The maximum AO adsorption conditions by AMS were at pH 7, optimum at a contact time of 5 minutes, and maximum at a concentration of 40 mg/L with an adsorbent ratio of 1:1. The adsorption kinetics and isotherm more closely followed the pseudo second-order and Langmuir isotherm with an adsorption capacity of 5.24 mg/g.

Heavy metals that are present in surface water and wastewater are becoming a severe environmental problem. Because of its toxicity, heavy metal removal has become the main priority for environmental concerns. Banana peels are low-cost agricultural waste that could be used for heavy metal adsorption in wastewater. The main objective of this study is to evaluate the effective powdered banana peel for the removal of copper (II) from aqueous solutions and real wastewater. The banana peels were collected from domestic waste and ground to get a particle size of 150 µm. Powdered banana peel waste adsorbent (PBPWA) contained moisture content, ash content, volatile matter, and bulk density of 3.8%, 3.5%, 37.5%, and 0.02 g/cm3, respectively. The Fourier-transform infrared spectroscopy (FTIR) results showed that the alkyne, aldehyde, and amide functional groups were dominant in the powdered banana peel surface, and the scanning electron microscope showed the morphology of the adsorbent. Physicochemical characteristics of the raw wastewater revealed that the concentration of Cu (II), Pb (II), COD, BOD5, and Cd (II) were 2.75 mg/L, 2.02 mg/L, 612.16 mg/L, 185.35 mg/L, and 0.01 mg/L, respectively. At pH 5, adsorbent dose of 2g/100 mL, initial copper (II) concentration of 80 mg/L, and contact time of 90 min, the maximum removal efficiency of synthetic wastewater was 96.8% and textile wastewater was 69.0%. The adsorption isotherm fitted well with the Langmuir isotherm model at R2 = 0.99. The kinetics of copper (II) adsorption followed the second-order kinetic model better. Finally, these studies showed that banana peel bio-adsorbent is a potential adsorbent for heavy metal removal from synthetic and textile wastewater.

Latar belakang: BOD, minyak dan lemak dalam air limbah domestik berbahaya bagi lingkungan. Polutan tersebut dapat dihilangkan dengan teknik adsorpsi menggunakan karbon aktif kulit pisang dengan efisiensi mencapai 70%. Tujuan penelitian yaitu mengkaji pengaruh dosis karbon aktif dan waktu kontak terhadap penyisihan BOD, minyak dan lemak, serta kinetika adsorpsinya, morfologi permukaan dan unsur kimia karbon aktif kulit pisang.Metode: Penelitian ini menggunakan Rancangan Acak Lengkap Faktorial. Faktor pertama dosis karbon (1,5 g, 3 g, 4,5 g) dan faktor kedua waktu kontak (30, 60, dan 90 menit), dengan 2 ulangan. Percobaan adsorpsi menggunakan sistem batch dengan gelas beker. Parameter penelitian meliputi BOD yang dianalisis dengan titrasi iodometri (SNI-6989.72:2009), serta minyak dan lemak dengan metode gravimetri (SNI-6989.10:2011). Analisis data menggunakan analisis deskriptif yang meliputi efisiensi penyisihan, kinetika adsorpsi, morfologi permukaan dan elemen karbon aktif. Hasil: : Dosis karbon aktif dan waktu kontak mampu menyisihkan BOD, minyak dan lemak hingga 24% dan 97%. Kinetika adsorpsi pseudo-second-order dengan R2 0,98 dan 0,99 menggambarkan adsorpsi BOD, minyak dan lemak. Karbon aktif sebelum adsorpsi pori-porinya terbuka dan permukaannya bersih, sedangkan setelah adsorpsi pori-porinya tertutup, permukaan padat, dan bergelombang. Elemen karbon sebelum adsorpsi terdiri dari C, O, K sebesar 76,53%, 19,46%, 2,24%, dan setelah adsorpsi terdiri dari C 78,94% dan O 19,87%.Simpulan: Dosis karbon dan waktu kontak berpengaruh terhadap penyisihan BOD, minyak dan lemak. Kinetika adsorpsi pseudo-second-order menggambarkan adsorpsi BOD, minyak dan lemak. Morfologi permukaan dan unsur karbon aktif sebelum dan sesudah adsorpsi berbeda. Title: Removal of BOD, Oil and Grease in Domestic Wastewater Using Activated Carbon from Banana PeelsBackground: BOD, oil and grease in domestic wastewater are harmful to the environment. These pollutants can be removed with adsorption techniques by activated carbons using banana peels with an efficiency up to 70%. The aim of the study was to analyze the impact of activated carbon doses and the contact time on BOD, oil and grease removal, as well as the kinetics of adsorption, surface morphology and chemical elements from banana peel activated carbon.Method: This experiment used a factorial completely randomized design. The first factor was carbon dosage (1.5 g, 3 g, 4.5 g) and the second was contact time (30, 60, and 90 minutes), with 2 replications. The adsorption experiment used a batch system with a glass beaker. The research parameters included BOD analyzed by iodometric titration (SNI-6989.72:2009), and oil and grease by gravimetric method (SNI-6989.10:2011). Data analysis using descriptive analysis which includes removal efficiency, adsorption kinetics, surface morphology and activated carbon elements.Result: The activated carbon dosage and contact time removed BOD, oil and grease up to 24% and 97%, respectively. Pseudo-second-order adsorption kinetics with R2 0.98 and 0.99 described the adsorption of BOD, oil and grease. Activated carbon before adsorption had open pores and a clean surface, while after adsorption the pores were closed, and the surface was solid and ridged. The carbon element before adsorption consists of C, O, and K at 76.53%, 19.46%, and 2.24%, and after adsorption consists of C at 78.94% and O at 19.87%.Conclusion: Carbon dosage and contact time affected the removal of BOD, oil and grease. The pseudo-second-order adsorption kinetics described the adsorption of BOD, oil and grease. The surface morphologies and elements from activated carbon before and after adsorption as different.
