TL;DR: Three technologies classified as Advanced Oxidation Processes (Conductive-Diamond Electrochemical Oxidation, ozonation and Fenton oxidation) have been compared to treat wastes produced in fermentation processes, and characterized by a significant color and a high organic load.

TL;DR: In this article, the technological and economic aspects of using the Fenton process to treat industrial wastewater containing morpholyne and diethylethanolamine, as well as sodium salts of naphthalene sulfonic acid and of ethylenediaminetetraacetic acid based on data obtained in pilot tests are discussed.
Abstract: The technological and economic aspects of using the Fenton process to treat industrial wastewater containing morpholyne and diethylethanolamine, as well as sodium salts of naphthalene sulfonic acid and of ethylenediaminetetraacetic acid based on data obtained in pilot tests are discussed. Chemical Fenton technology was tested using commercial 30–35% solutions of H2O2 and iron (II) salts, which was followed by the additional electrochemical destruction of organic pollutants in an undivided reactor with catalytic stable anodes (CSA) and 1 g L−1 NaCl as a supporting electrolyte and a source of active chlorine. An alternative electrochemical method involving the electrogeneration of hydrogen peroxide in polluted water at the gas
-diffusion cathode was studied both with the addition of ferrous salt to the electrolyte prior to electrolysis (in-cell electro-Fenton) as well as with the post-electrolysis addition of Fe2+ in another reactor (ex-cell electro-Fenton). The accumulation of hydrogen peroxide in concentrations sufficient for the mineralization of organic pollutants was achieved in both cases with near 100% current efficiency. In comparison with wastewater treatment processes which use a purchased hydrogen peroxide reagent, the Fenton-like processes achieved an economic savings of as much as 64.5% in running costs due to the on-site electrochemical generation of H2O2. Preparative electrolysis in the membrane reactor showed higher current efficiencies and lower specific energy consumptions for H2O2 electrogeneration in comparison with the results of tests carried out in an undivided cell.

TL;DR: These studies illustrate the successful use of biosensors for the detection of sulfur dioxide at the relatively low potential of +0.3 V versus AgCl and should provide useful alternatives for decentralised environmental studies.

TL;DR: In this article, a systematic study of the adsorption competition between the three inorganic halides Cl −, Br −, and I −, with the possible interference of ions from the supporting electrolyte, was performed on polycrystalline electrodes of high reproducibility.

TL;DR: In this article, the effect of pH (3, 6, or 10), applied current density (j apl ǫ −2 ), and absence or presence of Cl- ions (25mM) in the supporting electrolyte (aqueous 0.10m Na 2 SO 4 ) is investigated, while the picloram concentration, solution chemical oxygen demand (COD ) and total organic carbon content (TOC ), and energy consumption are monitored as a function of electrolysis time.
