Utilization data of Azadirachta indica leaf powder (Neem) as an adsorbent to remove nine trace metals from Aqueous solutions.

Given the urgent need to save the environment from chemicals used in the water treatment process, natural alternatives were essential to remove suspended matters such as chemicals, and other suspended particles. Recently, some plant leaves were utilized as an adsorbent matter for trace metals from the aqueous medium. Azadirachta indica (Neem) leaves one of the natural resources that demonstrated effectiveness to remove some trace metals from aqueous solutions. In this study, five treatments were examined to observe the effect of particle size (<63µm, 250µm) and weight differences (0.1 g. L-1, 0.5 g. L-1) on removing nine trace metals from the aqueous solutions. Analysis of variance (One-way ANOVA) test was characterized by a significant variation (P > 0.05 at 95% confidence interval) between treatments.
