“…Sivaprakash et al. (2020) published in an earlier issue, studied the potential of the powdered form of Acacia tortilis to remove cadmium from a synthetic solution, tested the effect of operating conditions on metal removal, and also carried out detailed kinetic studies. The effect of operating parameters, namely, initial pH (1.0–10.0), cadmium concentration (50–200 mg/L), biosorbent dose (0.5–4.0 g/L), and agitation speed (0–400 rpm), on the cadmium removal was investigated by the authors.…”
