Arsenic (III) Biosorption with Fenugreek (Methi) Seed Powder as a Low-cost Biosorbent

Abstract

This research study focuses at the use of fenugreek seed powder as a bio adsorbent for removing arsenic from aqueous media. Metal biosorption research on Fenugreek seed powder has been studied in just a few studies. SEM, FTIR, and XRD were used to investigate the constituents and properties of fenugreek seed powder, which revealed the constituents and properties that enabled the arsenic biosorption process to succeed. To investigate the strength of arsenic adsorption using Fenugreek seed powder as a bioadsorbent, the effects of primary parameters including contact time, dose, concentration, pH, and temperature were used. The report of these parameters suggested that as the parameters increased, the efficient removal of arsenic increased until equilibrium was reached, but no successful results were seen after gaining the equilibrium. The biosorption process to Freundlich isotherm and pseudo kinetic order in liner form with better correlation coefficients was verified by a survey of biosorption isotherms and kinetic results. The system was endothermic, random, and favourable with biosorption characteristics at various temperatures, as determined by the thermodynamic constants. As a result of these findings, fenugreek seed powder has been modified for arsenic adsorption.
