Cyanide

The transport of zinc complexes ions through an anion exchange membrane was evaluated by the treatment of solutions with and without cyanide. The ionic transport was analyzed as a function of the applied current density and of the cyanide and hydroxyl concentration. Experimental results showed that

The results of laboratory tests are presented in this paper, which demonstrate a possibility of using the advanced oxidation process for the removal of cyanide from the water. A comparative analysis was carried out for the processes of ozonation, oxidation with hydrogen peroxide and advanced oxidati

The generation of hydrogen peroxide and the decomposition of free cyanide by ultrasonic waves were studied and the statistical analysis of the results for significance was performed using Ergun’s test (essentially One-way Analysis of Variance (ANOVA) for gradients). Effects of the ultrasonic intensi

The behaviour of sulfonated polyethersulfone membranes in the reverse osmosis treatment of aqueous solutions containing ammonium, cyanide and sulphate ions is described in this paper. Experimental tests were performed in an INDEVEN planar membrane test module, which provides data concerning the beha
