An Innovative Method for Detecting and Removing Fluorescein Contamination in Wastewater: Using Fe3O4@SiO2-PANI Nanocomposite as an Excellent Adsorbent |
|
| چکیده انگلیسی مقاله |
Fluorescein (FL), a widely used synthetic organic compound prized for its intense fluorescence and visibility, has extensive applications in medicine, biology, and environmental monitoring. However, the increasing prevalence of FL in wastewater streams raises significant environmental concerns, necessitating effective removal strategies. In this study, the magnetic nanocomposite, Fe3O4@SiO2-PANI, was synthesized and investigated for its efficacy in removing and quantifying FL using UV-visible spectrophotometry. The research illustrates the steps involved in synthesizing the nanosorbent and details its structural characteristics using FT-IR, SEM, and EDX methods. Additionally, it emphasizes how effectively the nanocomposite can extract FL when particular conditions are applied. The process involved using the nanosorbent with a mass of 65.0 mg along with a phosphate buffer solution at 0.1 M to maintain a consistent pH level of 10.0. These conditions were held for an accumulation time of 30 min. Additionally, the optimal parameters for the desorption process were attained, which included 2.5 mL of HCl (0.1 M) and a contact time of 30 min. The technique employed allowed for a linear calibration curve that facilitated the measurement of FL concentrations ranging between 0.27 and 5.3 mg L-1. Notably, the method was precise in detecting FL at a lower limit of 0.011 mg L-1 and quantifying it at levels down to 0.037 mg L-1. The optimized conditions yielded an adsorbent capacity of 549.45 mg/g, along with a removal percentage exceeding 94. |
