Phytodegradation potential of bisphenolA from aqueous solution by Azolla Filiculoides

Area of Science:

• Environmental Science
• Bioremediation
• Aquatic Plant Studies

Background:

• Bisphenol A (BPA) is a toxic, persistent organic pollutant causing global environmental concerns.
• Conventional BPA removal methods are often costly and energy-intensive.

Purpose of the Study:

• To investigate the efficacy of Azolla Filiculoides in removing BPA from aqueous solutions.
• To determine the optimal conditions for BPA removal using Azolla Filiculoides.

Main Methods:

• Azolla Filiculoides biomass (0.3-1.2 g) was cultured in solutions with varying BPA concentrations (5-50 ppm).
• BPA concentration was monitored every two days using UV-visible spectrophotometry at λmax = 276 nm.

Main Results:

• Azolla Filiculoides demonstrated significant BPA removal, achieving 60-90% efficiency.
• Removal efficiency increased with lower BPA concentrations and higher Azolla biomass.
• Over 90% BPA removal was observed at 5 ppm BPA concentration with 0.9 g biomass.

Conclusions:

• Azolla Filiculoides effectively removes BPA from water via phytodegradation.
• Phytoremediation using Azolla offers a cost-effective and energy-efficient alternative to conventional BPA removal techniques.
