Heavy metals (HMs) pollution is one of the most hazardous toxins that can harm people's health, heavy metals (HMs) are naturally occurring components of the environment. Because of their toxicity, enduring nature, and capacity for bioaccumulation, heavy metals (HMs) are well-known environmental pollutants. As a result, excessive amounts of heavy metals like iron, aluminum, strontium, etc. are released into natural resources including soil and marine environments. Volcanic eruptions and the weathering of rocks that contain metals are examples of their natural origins; human sources include mining and other industrial and agricultural activities.

In this study we made Nanomaterial Composites from aniline in organic solvent and potassium permanganate in water and made Polyaniline-intercalated manganese dioxide Nanomaterial Composites and took some quantities from this composite nanomaterial on solutions contains different concentration of individual element such as iron, strontium and aluminum and study the effects of contact time, ionic strength, dose of nanomaterial and concentration of iron, strontium and aluminum elements, then calculated the percentage removal which is raised by increasing these effects.

The kinetic is the second-order kinetic model in terms of higher correlation coefficients (0.98 and 0.95) for Fe and Sr respectively, while in case of Al the data has showed good compliance with pseudo first order with higher correlation coefficients (0.95).
