Removal of Pharmaceutical Drug from Water Using Activated Kaolinite–TiO2 Nanocomposite
Pharmaceutical contamination of water has been an emerging environmental area of concern. A large amount of pharmaceuticals is discharged into the nature through human utilization and excretion and is not treated properly by municipal sewage treatment plants. Pharmaceuticals are also disposed into the nature by pharmaceutical industries. Levofloxacin (LVF) is one of them. LVF, a famous fluoroquinolone (FQ) is widely adopted drug owing to its effective activity against microbes. LVF finally enters water environment, because only 15–20% metabolizes in living beings. FQs vary from mg dm−3 to ng dm−3 in wastewater. Incessant revelation of microorganisms to FQs (2–5 mg dm−3) will help bacterial resistance to FQs. The present investigation focuses on feasibility of using Activated Kaolinite–TiO2 (AK–TiO2) nanocomposite for the removal of LVF. In this study, various factors considered for the removal of LVF are the effect of initial LVF concentration, effect of AK–TiO2 nanocomposite and effect of contact time. The AK–TiO2 nanocomposite showed boosted photocatalytic activity for the photodegradation of LVF. The photodegradation of LVF improved with an enhancement of AK–TiO2 nanocomposite dosage and photodegradation time. The maximum LVF removal efficiency of 64% was recorded for AK–TiO2 dosage of 500 mg/l with photodegradation time of 300 s. With an enhancement in the initial LVF concentration, the photodegradation reduced, this is because enhancement in the LVF increases anions.
