Synthesis of Bio Adsorbent from Parthenium Weed (Parthenium hysterophorus) Plant Biomass and Its Application in Removal of Hexavalent Chromium Ion from Aqueous Solution

Abstract

Rapid industrialization leads to serious environmental hazards due to increasing the release of toxic metal into the environment.
The study focuses on utilizing Parthenium hysterophorus weed biomass as a novel bio adsorbent for removing hexavalent
chromium (Cr (VI)) ions from aqueous solutions. The bio sorbent was characterized using FT-IR provides valuable insights into
the chemical interactions between the functional groups of the bio sorbent and the Cr (VI) ions, shedding light on the mechanism
of adsorption and the role of specific functional groups in the removal process. Batch adsorption experiments determined
optimal conditions: pH 2, 90 minutes contact time, 1g adsorbent dosage, and 150 mg/L initial metal ion concentration. The
study concludes that Parthenium bio sorbents are effective, low-cost alternatives for Cr (VI) ion removal, showcasing high bio
sorption capacity and potential for further exploration with other heavy metals. Suggesting further exploration of its scalability
and practical application for environmental remediation. Recommendations include optimizing the bio sorption process and
investigating bio sorbent regeneration for sustainable water treatment solutions.
