experimentsKinetic adsorption experiments were performed to assess As(V)adsorption by adsorbents as a function of contact time. 0.04 g adsorbents were added to 20 mL (2 g L−1) of 100 mg L−1As(V)solution in 68 mL digestion vessels (Environmental Express) atroom temperature (22 ± 0.5◦C). All treatments were carried out in triplicate and the means were reported with standard deviations.
