Method & Evidence

AimTo develop and evaluate a magnetite-impregnated biochar composite derived from Parthenium hysterophorus for the efficient removal of Cr(VI) from tannery industrial wastewater.

MethodExperimental design and chemical analysis

ProcedureA composite adsorbent was synthesized by impregnating Parthenium hysterophorus biochar with magnetite. Its properties were characterized using BET surface area analysis, XRD, SEM, and FTIR. A full factorial experimental design (Box-Behnken) was employed to optimize removal efficiency by varying pH, initial Cr(VI) concentration, contact time, and adsorbent dose. The adsorption process was modeled using the Langmuir isotherm.
