For replacing the un-ecofriendly gold recovery methods, photoreduction catalyzed by TiO2 is proposed as an environmentally benign alternative method for gold recovery. In this study, the photocatalytic reduction was carried out by batch technique, in which the influences of reaction time, TiO2 photocatalyst dose, and initial Au(III) concentration were evaluated to get the optimal condition. In addition, the influence of Ag(I), Cu(II), and Fe(III) that are usually found along with gold in the… CONTINUE READING
