摘要

摘要发现在金属-碘-过氧化氢-酸-有机溶剂体系中，金属与过氧化氢的直接氧化反应与与碘的反应具有竞争性，从而导致铅的消耗率异常之高。研究了该反应在无其他金属存在和有其他金属存在时的动力学。在这些条件下，其他金属的消耗速度要慢得多，这一方面与它们与碘的反应没有竞争性；另一方面，它们的产物明显地延缓了铅与过氧化氢的直接作用。

Anomalously High Rates of Lead Consumption in Reaction Mixtures Containing Iodine, Hydrogen Peroxide, or Both Oxidants Simultaneously

Abstract—The direct oxidation of a metal with hydrogen peroxide in the metal–iodine–hydrogen peroxide–acid–organic solvent system, which is competitive with the reaction with iodine, is found to cause the anomalously high rates of lead consumption. The kinetics of this reaction in the absence and presence of other metals is studied. Under these conditions, other metals are shown to be consumed much more slowly, which is not competitive, on the one hand, with their reactions with iodine; on the other hand, their products appreciably retard the direct interaction of lead with hydrogen peroxide.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
