Comparative Evaluation of Phytoremediation Efficiency of Azolla pinnata and Pistia stratiotes in Methylene Blue Contaminated Water

Dye pollution occurs when synthetic dyes  from industrial are released into waterways, often leading to environmental harm due to their persistence and potential toxicity and become significant environmental concern. The dye  wastewater need to be treat before discharge to water body. However the current methods are costly and some of  the treament can treat the various types of organic and inorganic compund in dye. Phytoremediation presents a promising eco-friendly approach for treating textile dye contaminants. This study evaluated the comparative performance and efficiency of Azolla Pinnata and Pistia Stratiotes in removing MB from contaminated water. Laboratory experiments were conducted to assess the uptake and absorption capabilities of both aquatic plants over a 12-day period. The reduction of  the MB before and after phytoremediation process were analyze by using spectrophotometer. Results indicated that both Azolla pinnata and Pistia stratiotes effectively reduced MB concentrations, with  achieved a removal efficiency of approximately 97.8 % for Pistia Stratiotes, 93.9% for Azolla pinnata and 95.1 % ( Azolla pinnata and Pistia stratiotes) . The high removal of  through this aquatic plant were due to the capability of the plant to absorb MB  especially  through the roots that rich with microbial activity. Overall, this comparative study highlights the potential of Azolla pinnata and Pistia stratiotes as efficient phytoremediators for treating Methylene Blue contamination in aquatic ecosystems, underscoring their application fullfill Sustainable Development Goal 6 (Clean Water and Sanitation).
