Adsorption of Aniline from Aqueous System by Highly Fluorinated Polymers of Intrinsic Microporosity (PIM-2)

Abstract

Adsorption of Aniline from Aqueous System by Highly Fluorinated Polymers of Intrinsic Microporosity (PIM-2) Bekir SATILMIŞ 10(3): 1886-1898, 2020 Adsorption of Aniline from Aqueous System by Highly Fluorinated Polymers of Intrinsic Microporosity (PIM-2) 1888 (≥99.9%, MeOH), aniline (99%) and dimethylformamide (99.8%, DMF), were received from Sigma Aldrich and used as purchased. Synthesis and characterization of PIM-2 Synthesis and characterization of PIM-2 polymer was carried out as described in our previous study (Satilmis and Uyar, 2019). Briefly, TTSBI, K2CO3, and anhydrous DMF were mixed in a flask under argon atmosphere. Then, complete dissolution was achieved by heating the mixture to 100 °C. Meanwhile, DFBP was dissolved in anhydrous DMF and this solution was injected into the reaction mixture. The reaction was executed at 100 °C for 48 h and the product was treated with an aqueous HCl (5% v/v) before drying at 150 o C for overnight. Methods FT-IR spectrum was recoded on a Bruker Vertex 70 FT-IR spectrometer. 1 H NMR spectrum was compiled using a Bruker (DPX-400 MHz) NMR spectrometer in CDCl3. Thermal changes of PIM-2 powder were investigated using TA Q500 thermogravimetric analyser under nitrogen atmosphere. Quantitative determination of aniline was accomplished by Genesis10s UV-Vis spectrometer.
