Fabrication of Novel Bentonite-Anthracite@Zetag (BT-An@Zetag) Composite for the Removal of Arsenic (V) from an Aqueous Solution

The arsenic (As) pollution of water has been eliminated via intensive scientific efforts,
with the purpose of giving safe drinking water to millions of people across the world. In this
study, the adsorption of As(V) from a synthetic aqueous solution was verified using a BentoniteAnthracite@Zetag (BT-An@Zetag) composite. The SEM, FT-IR, XRD, DSC, TGA, and SBET techniques
were used to characterize the (BT-An@Zetag) composite. The adsorption of As(V) was explored using
batch adsorption under varied operating scenarios. Five kinetic modelswere used to investigate
kinetic data, whereas three isotherms had been used to fit empirical equilibrium data. According to
the findings, the adsorption mechanism of As(V) was best described by the Freundlich isotherm with
a maximum monolayer coverage of 38.6 mg/g showing pseudo-second-order mode. The estimated
enthalpy (H◦
) indicates that the adsorption process is both chemical and endothermic.The calculated
free energy (G◦
) indicates that the reaction is nonspontaneous.
