This document summarizes research on using Moringa oleifera seeds to remove heavy metals from water. Moringa seeds were collected and prepared by drying, peeling, and grinding. Samples were tested with varying dosages of Moringa powder over various time periods from 30 minutes to 20 days. Atomic absorption spectrometry showed heavy metal concentrations decreased significantly over time. Optimum removal occurred with a dosage of 2.5 g/L over 20 days, reducing metal levels to permissible limits. The research demonstrated Moringa's effectiveness as a natural coagulant for water purification.
