Scientists have found that moringa seeds can remove microplastics from water. The study compared moringa with a chemical treatment and found similar results.

Moringa, also known as white acacia, is a common plant native to India. Its leaves and seeds are nutritious and widely consumed. Researchers at the Institute of Science and Technology of São Paulo State University in Brazil have been exploring moringa's potential for water purification.

The study published in ACS Omega found that the saline extract from moringa seeds performs similarly to aluminum sulfate, a chemical treatment used in water treatment plants. The researchers tested this method on contaminated tap water with polyvinyl chloride (PVC) microplastics.

The team added PVC microplastics to tap water and then treated it with moringa seed extract or aluminum sulfate. They compared the results using scanning electron microscopy (SEM) to count microplastic particles before and after treatment. Both treatments showed similar levels of microplastic removal.

The researchers are now testing moringa seed extract on real-world water sources, including the Paraíba do Sul River, which supplies São José dos Campos.

Why It Matters

This study is important for Indian students because it shows that a common plant can help remove microplastics from drinking water. This could be especially useful in rural areas where access to clean drinking water is limited.

Key Facts

• Moringa seeds can remove microplastics from water using a saline extract.
• The study compared moringa with aluminum sulfate and found similar results.
• PVC microplastics were used in the study because they are considered harmful to human health.
• The researchers tested moringa seed extract on contaminated tap water and real-world water sources.
• The method could be cost-effective and efficient for small-scale use, such as on rural properties.
