Abstract:

 

The removal of bromothymol blue (BTB) from aqueous   solution was studied by electrocoagulation (EC) technique using aluminum   electrodes. The various experimental conditions known to influence the EC   process were parameterized, including the effects of temperature,   concentration, current density, pH, and treatment time. The results obtained   have shown that optimum removal efficiency of 99.9% was realized at a   current density of 20 mA/cm22^{2} and pH of 4.7. The adsorption process   showed a pseudo-first-order kinetic model as the best fit to the EC data.   Freundlich and Langmuir adsorption isotherms supported the adsorption of BTB   on aluminum hydroxide being the in situ generated electrocoagulant. From the   thermodynamic parameters, the adsorption of BTB is spontaneous, as indicated   by the negative value of the Gibbs free energy.
