FIELD: determination of stability of high-concentration solutions of hydrogen peroxide. SUBSTANCE: increased authenticity and timeliness of evaluation of stability of hydrogen peroxide in large-sized complex vessels are achieved thanks to establishment of dependence of activity of acoustic emission originated in process of release of oxygen from hydrogen peroxide on rate of its liberation which is found experimentally. In process of usage activity of acoustic emission emerging in tested peroxide is recorded and rate of liberation of oxygen from peroxide is determined by change of activity of acoustic emission with the use of established dependence. This rate is utilized to pass judgment on stability of tested hydrogen peroxide. EFFECT: increased authenticity and timeliness of evaluation of stability of hydrogen peroxide. 1 dwg
