摘要

研究了电解和超声波对硫酸钠水溶液中大肠杆菌数量的综合影响。还确定了用这种方法净化水灭活细菌的动力学。结果表明，水溶液经超声波和电化学处理后，细菌的灭活率明显提高。有人认为，联合处理过程中形成的羟基自由基是导致细菌死亡的原因。研究发现，羟基自由基的形成速率与细菌的灭活率之间存在相关性。

The Combined Effects of Electrochemical and Ultrasonic Treatment for Water Purification from Pathogenic Contaminants Based on the Example of Escherichia coli

The combined effects of electrolysis and ultrasound on the population of E. coli bacteria in an aqueous solution of sodium sulfate have been studied. The kinetics of bacterial inactivation with this method for water purification have been determined. It has been shown that the combined effect of ultrasonic and electrochemical treatment of an aqueous solution significantly increased the rate of bacterial inactivation. It has been suggested that hydroxyl radicals formed during combined treatment are responsible for the death of bacteria. A correlation has been found between the rate of formation of hydroxyl radicals and the rate of inactivation of bacteria.

期刊介绍： Biophysics is a multidisciplinary international peer reviewed journal that covers a wide scope of problems related to the main physical mechanisms of processes taking place at different organization levels in biosystems. It includes structure and dynamics of macromolecules, cells and tissues; the influence of environment; energy transformation and transfer; thermodynamics; biological motility; population dynamics and cell differentiation modeling; biomechanics and tissue rheology; nonlinear phenomena, mathematical and cybernetics modeling of complex systems; and computational biology. The journal publishes short communications devoted and review articles.
