Use and Efficiency of Alginic Acid to Remove Some Heavy Elements from Pollutant Water

Abstract

In this work, heavy metals (Pb, Cr, Co, and Fe) were removed from polluted water using a chemical technique involving the addition of a biological polymer (alginic acid). For each element, different concentrations (0.5,1,1.50,2 ppm) were present. Within 72 hours, the pH 5 and duration of the test were evaluated, and the remaining amounts of the stated elements were detected by measuring the absorbance using the atomic absorption spectrometry technique. The results revealed that the extraction of the examined components was acidic. The greatest lead concentration was 2ppm, followed by 1.5 ppm of chromium, 0.5 ppm of iron, and 0.5 ppm of cobalt. Finally, we encourage researchers to do research on alginic acid for its easy availability and preparation.
