Adsorption studies. (A) qe value as a function of time at different pH for PSB. (B) Pseudo-second-order model for PSBs. (C) qe value as a function of time at pH 7.0 for orthophosphate ions. (D) Pseudo-second-order model for orthophosphate ions. Results are the average of three replicates with their respective deviation.
