EFFICIENT BIOCOAGULANT Azardicta Indica BARK POWDER FOR ARSENIC (III) REMOVAL IN THE SOLUTION PHASE

Abstract

This study aims to remove arsenic from groundwater by employing a series of batch studies on Azardicta Indica bark powder that vary in terms of physic-chemical factors such as contact time, dose, pH, initial arsenic content, and temperature. The rate of arsenic absorption decreased as it moved farther inside the biosorbent particles from its initial quick pace. At a pH of 4.0-6.0 and a dosage of 1.5 gm, the impact of contact duration on arsenic biosorption was investigated for 30 minutes.As the initial arsenic concentration rises, the proportion of arsenic biosorption decreases because mass transfer between the solute and solution interface is impeded at higher concentrations. Through the assessment of the biosorbent's mass transfer coefficients, the experimental outcomes were accurately documented in terms of Freundlich and to some degree Temkin isotherms with values of R2 0.998 and 0.956, respectively.
