  • Exploitation of Bentonite for Wastewater Treatment

     · A fixed mass m 0 = g of bentonite is contacted with the aqueous solution of phenol with an initial concentration of C 0 = −3 M. The mixture is then stirred at 500 rpm for an adsorption time t (tads). For each experiment, the solution pH is adjusted, as necessary, by the addition of HCl ( N) or NaOH ( N).
