(a) Effect of pH value (conditions: MG—20 mg/L, time—24 h, Fe₃O₄@AJPAL—50 mg, temperature—25°C, and agitation—100 rpm), (b) contact time (conditions: MG—20 mg/L, pH—7, Fe₃O₄@AJPAL—50 mg, agitation—100 rpm, and temperature—25°C), (c) adsorbent dose (conditions: MG—20 mg/L, pH—7, time—120 min, temperature—25°C, and agitation—100 rpm), and (d) initial MG concentration (conditions: time—120, Fe₃O₄@AJPAL—50 mg, pH—7, temperature—25°C, and agitation—100 rpm) on the adsorption of MG on Fe₃O₄@AJPAL.
