Abstract

Air limbah farmasi mengandung beberapa obat-obatan, salah satunya ciprofloxacin (CPFX) yang merupakan antibiotik yang paling banyak digunakan. Kandungan ciprofloxacin dalam effluen IPAL yang terdeteksi berkisar antara 31-50 mg/L. Berbagai upaya dalam mengurangi konsentrasi ciprofloxacin dalam badan air telah dilakukan. Besi nano valensi nol (nZVI) memiliki keunggulan berupa reduksibilitas dan reaktivitas yang baik. Namun, efektivitas reduksi nZVI akan meningkat jika dilapisi dengan nanopartikel lain. Sedangkan MXene (Ti3C2Tx) merupakan material berlapis dua dimensi yang memfasilitasi transport elektron kecepatan tinggi, dapat menjadi bahan pelapis nZVI untuk meningkatkan efisiensinya. Pembuatan komposit nZVI dan MXene dilakukan dengan mereduksi FeCl2.4H2O dan sintesis TiAlC2 dengan LiF/HCl. Kemudian dilakukan reduksi ciproflokxacin dengan konsentrasi tertentu menggunakan nanokomposit nZVI, MXene, dan campuran dari nZVI-MXene. Larutan CPFX yang akan direduksi dikondisikan terlebih dahulu dengan variasi pH 4, 7, dan 9. Karakterisasi dilakukan untuk mengetahui morfologi, persebaran dan ikatan kimia sampel. Sintesis nanokomposit nZVI-MXene menghasilkan perubahan morfologi pada material dibandingkan nZVI dan MXene murni. Nanokomposit nZVI-MXene memiliki luas permukaan spesifik yang meningkat menjadi 1,47 m2/g dan diameter pori lebih kecil 20,6 nm. Hal ini menunjukkan adanya ikatan antara MXene dan nZVI. Efisiensi penyisihan nZVI-MXene terhadap larutan CPFX optimal pada konsentrasi 100 mg/L dengan nilai 96%, ketika konsentrasi CPFX melebihi 100 mg/L maka efisiensi penyisihan dari material tersebut akan turun sebesar 11%. Material nZVI, MXene, dan nZVI-MXene memiliki efisiensi penyisihan optimal terhadap 100 mg/L CPFX pada pH 9 dengan nilai berturut-turut sebesar 87%, 91%, dan 96% dengan waktu kontak optimum pada saat adsorpsi CPFX adalah 30 menit.

Pharmaceutical wastewater contains several drugs, including ciprofloxacin (CPFX), the most widely used antibiotic. The detected ciprofloxacin content in the effluent of WWTP ranged from 31-50 mg/L. Various efforts have been made to reduce the concentration of ciprofloxacin in water bodies. Zero valent nano iron (nZVI) has the advantage of good reducibility and reactivity. However, the effectiveness of nZVI reduction will increase if coated with other nanoparticles. While Mxene (Ti3C2Tx) is a two-dimensional layered material that facilitates high-speed electron transport, it can be a coating material for nZVI to increase efficiency. NZVI and MXene composites were manufactured by reducing FeCl2.4H2O and synthesizing TiAlC2 with LiF/HCl. Then, ciprofloxacin reduction was carried out with a particular concentration using nZVI, MXene, and a mixture of nZVI-MXene nanocomposites. The CPFX solution to be reduced was conditioned first with pH variations of 4, 7, and 9. Characterization was carried out to determine the sample's morphology, distribution, and chemical bonds. The synthesis of nZVI-MXene nanocomposites resulted in morphological changes in the material compared to pure nZVI and MXene. The nZVI-MXene nanocomposite has an increased specific surface area of 1,47 m2/g and a smaller pore diameter of 20,6 nm. This indicates a bond between MXene and nZVI. The efficiency removal of nZVI-MXene against CPFX solution is optimal at a concentration of 100 mg/L with a value of 96%; when the CPFX concentration exceeds 100 mg/L, the efficiency removal of the material will decrease by 11%. nZVI, MXene, and nZVI-MXene materials have optimal efficiency removal against 100 mg/L CPFX at pH 9 with consecutive values of 87%, 91%, and 96%, with optimum contact time during CPFX adsorption is 30 minutes.
