Adsorption of Chromium (VI) from Aqueous Solution Using Phytoremediation

Abstract

The goal of this study is to assess how well sunflower waste can remove chromium (VI) from an under various process settings, an aqueous system is examined. Sunflower stalks were burned to create adsorbents, which were subsequently used to soak up water in a variety of applications. The use of Sunflower (Helianthus annuus L.) It has been investigated as a Cr (VI) reducing agent for the removal of hexavalent chromium from synthetic waste water. Adsorbent properties were determined via the use of ultraviolet (UV), x-ray diffractograms (XRD), infrared (FTIR), and magnetic hysteresis methods. 20 milligrams per liter of hexavalent chromium experiments a study on chromium recovery in batches found that increasing the pH of the aqueous solution enhanced metal recovery. pH = 7, adsorbent dose of 0.03 gr, and 25°C temperature were shown to be optimal for the removal of Cr (VI). Cr (VI) may be removed from synthetic model effluent by using Sunflower, according to the results of this study. The Sunflower plant has successfully cleaned synthetic waste water by rapidly removing Cr (VI) from aqueous solution.
