Batch absorption experiments were performed to study the effects
of adsorption parameters like contact time (5–300 min), temperature
(20–40 °C) and pH (2–12) on the removal of HA. The batch experiments
were carried out in a set of 250 mL Erlenmeyer flasks, adding 0.05 g of
each adsorbent and 50 mL micropollutant at different concentrations.
All batch reactors were placed on a laboratory shaker (Carrousel
model) with a controlled horizontal oscillation between 180 and 200
blows per minute and the temperature was maintained at 20 °C
