In terms of volumetric removal flux, chlortetracycline and equivalent O 2 flux of chlortetracycline maximum were calculated as 2.05 and 3.56 mg/L.d. At the same time, nitrification and denitrification efficiency were obtained as 99 %. At the end of the study, PCT and CTC were removed at maximum 99.8 % and 66 % under the same conditions, respectively. In this study, CTC and PCT drugs together with ammonium (NH 4-N) and nitrate (NO 3-N) pollutants were simultaneously removed in a single reactor. For this purpose, it is important to remove these pollutants from the environments where they are located. For this reason, water resources are exposed to more and more drug pollution every day. Then PAN, NaPF 6, and Ti 3C 2T x solutions are loaded into a syringe for the electrospinning process and thus we obtain the CPE (Composite Polymer Electrolyte) fiber film.Ĭhlortetracycline (CTC) and paracetamol (PCT), which are among the most widely used drugs today, have started to be detected in groundwater and surface waters. Later, Ti 3C 2T x is added and mixed for 6 hours at room temperature. In this procedure PAN(Polyacrynitrile), NaPF 6 (Sodium hexafluorophosphate) solution (N/Na∼16) (9 wt%) is synthesized using DMF (Dimethylformamide) by mechanical stirring for 8 hours at room temperature. The four distinct MXene-based CPEs samples are fabricated by altering the MXene concentration from 0 mg, 20 mg, 40 mg, and 60 mg. Electrospinning creates free-standing MXene-based CPEs samples. The sample is then dried at 200 ☌ in the vacuum condition for 12 hours, to obtain finally Ti 3C 2T x powder. The sediments are rewashed with 1 liter of deionized water using vacuum-assisted filtering using a 0.22 mm PVDF membrane. The sample is then centrifuged with deionized water and washing cycles are repeated until supernatant pH is reached around 6. ![]() ![]() The reaction conducted for one day at room temperature. ![]() As the interaction between Ti 3AlC 2 and HF is exothermic, the powder is added gradually to reduce bubbling. For this 0.5 gm of Ti 3AlC 2 powder is added to 10 ml of 48 % HF in a Teflon beaker. MXene is synthesized by etching aluminium from MAX-phase with HF acid.
