(a) The effect of contact time on acetic acid adsorption onto RH-AC and PP-AC, at contact time 90, initial concentration of 1.5 M, 0.1 g/50 mL, and agitation speed of 120 rpm. (b) The effect of adsorbent dosage on acetic acid adsorption onto RH-AC and PP-AC, contact time 90, initial concentration of 1.5 M, and agitation speed of 120 rpm. (c) The effect of adsorbate concentration on acetic acid adsorption onto RH-AC and PP-AC, contact time 120 min, adsorbent dose 0.1 g/50 mL, agitation speed of 120 rpm, and temperature.
