A method of oxidative mineralization of the salicylic acid and its derivatives as well as medicinal products containing salicylic acid as the active ingredient was investigated. Destruction of the organic compounds is possible both in the electrolyte under the oxidant, electrochemically formed in situ in the sulphuric acid solutions, and at the anode so. Simultaneously, at the cathode, reduction of the zinc ions, contained in a number of medicinal products, is possible. Final products of the oxidation are simple non-toxic organic compounds, carbon dioxide, and water. This process is the most effective in the 40% sulphuric acid at the current density of 0.5–0.8 A/cm2 and the temperature of 30–50 °C.

Presence of chlorinated organic compounds in water bodies has become a concern among governments, health authorities and general public. Oxidation of organic compounds in water under high temperature and pressure is considered as a promising technique, but usefulness of the technique to mineralize 2,4-dichlorophenoxyacetic acid (2,4-D) is not well understood. This article aimed to elucidate degradation characteristics of 2,4-D in both subcritical and supercritical waters by laboratory batch experiments. 2,4-D degradation, total organic carbon (TOC) removal and dechlorination increased with increasing reaction time and temperature especially in subcritical waters, while dechlorination was a major step. 2,4-dichlorophenol (2,4-DCP) and acetic acid were the main degradation intermediates both in subcritical and supercritical waters. Though 2,4-D disappeared almost completely in subcritical waters near critical region (≈99%), significant amounts of TOC and organic chlorine still remained as 2,4-DCP and acetic acid. But TOC removal and dechlorination were significantly enhanced (≈95 and 91% respectively) in supercritical waters. Complete mineralization of 2,4-D in subcritical waters required a considerably longer reaction period, while the mineralization was almost complete within a short reaction period in supercritical waters. This is an important information of practical significance for oxidative degradation of chlorinated pesticides similar to 2,4-D.
