Abstract
Wastewater pollution poses a significant threat to the environment and human health. Recent studies have shown a disturbing increase in the levels of water contamination. However, phytoremediation is a low-cost, eco-friendly and effective technology that utilizes plants to treat wastewater. In this study, duckweed (Lemna minor) used for phytoremediation to address the high concentration of ionic dyes in contaminated water. The findings of this study were remarkable, with Lemna minor showing impressive results in reducing both Methylene Blue (up to 99%) and Congo red (up to 25%) after a 24-day period. Furthermore, the relative growth rate of the plants was analyzed, revealing that the growth rate of Lemna minor was higher after exposure to methylene blue than it was for Congo red. This study also employed FTIR to analyze the characteristics of the plant sorption process. Overall, this study highlights the effectiveness of using phytoremediation with duckweed for treating wastewater contaminated with dyes. The results provide a strong foundation for further research into using plants for treating water pollution.
