“…4 a). Treatments increased the SSA and decreased the D 43 , suggesting enhanced adsorption capacity and the promotion of electrostatic repulsion, respectively [21] . The SSA increased to 0.589, 0.649 and 0.437 m 2 /g after individual treatments and 0.644, 0.910 and 0.502 m 2 /g after combination treatments, from DWS values of 0.502, 0.592 and 0.326 m 2 /g, respectively for CAH, CCH and CPH.…”
