Removal of Paracetamol from Drinking Water by Coagulation and Effect of Temperature

Öz

In this study, the removal of paracetamol by using four different coagulants (FeCl3.6H2O, MgCl2.6H2O, Al2(SO4)3.18H2O, FeSO4.7H2O) from drinking water was investigated. All of the coagulation experiments were performed by using jar test. After the determination of optimum coagulant dosage and pH, coagulation experiments were performed at four different temperatures to detemine the effect of temperature. The highest removal efficiency of paracetamol was obtained with FeCl3.6H2O and at pH 11. While paracetamol removal efficiency was determined 22% with FeCl3.6H2O under optimum conditions, at 10C, it was removed with 53% efficiency at 25C under same conditions. It was determined that the removal efficiency increased with increasing temperature for all coagulation experiments.

Parasetamolün İçme Sularından Koagülasyonla Giderimi ve Sıcaklığın Etkisi

Öz

Bu çalışmada, parasetamolün içme sularından koagülasyonla giderimi, dört farklı koagülant (FeCl3.6H2O, MgCl2.6H2O, Al2(SO4)3.18H2O, FeSO4.7H2O) kullanılarak araştırılmıştır. Tüm koagülasyon deneyleri jar test analizleri kullanılarak gerçekleştirilmiştir. Optimum pH ve koagülant dozlarının belirlenmesinden sonra sıcaklığın etkisinin incelenmesi amacıyla dört farklı sıcaklıkta (10, 15, 20 ve 25C) koagülasyon çalışmaları yapılmıştır. Parasetamolün en yüksek giderim verimi (%46) FeCl3.6H2O ile pH 11’de elde edilmiştir. FeCl3.6H2O ile optimum değerlerde 10C’de parasetamol giderim verimi %22 iken aynı şartlarda sıcaklık 25C’ye çıkarıldığında yüzde giderim verimi %53 olarak elde edilmiştir. Tüm koagülasyon deneylerinde sıcaklığın artmasıyla yüzde giderim veriminin arttığı tespit edilmiştir.
