Description
Изобретение относитс к способам очистки воды и водных растворов от ионов т желых металлов электрохимическим способом и может быть использовано дл очистки стоков металлургической, машиностроительной и других отраслей промышленности .The invention relates to methods for purifying water and aqueous solutions from heavy metal ions by an electrochemical method and can be used to purify wastewater from metallurgy, engineering and other industries.
Цель изобретени - повышение степени очистки и упрощение процесса получени асимметричного тока без применени дополнительных устройств.The purpose of the invention is to increase the degree of cleaning and simplify the process of obtaining asymmetric current without the use of additional devices.
Пример. Очистку воды и водных растворов от ионов т желых металлов провод т в электролизере, выполненном из чередующихс трех стальных и трех титановых электродов. Материалы электродов: нержавеюща сталь 12Х18Н10Т, титановый сплав ОТ4-0. Объем заливаемого раствора 50 мл; температура 20-25°С: рассто ние между пластинами 5-7 мм; электролиз провод т при плотности тока 16-17 А/дм2.Example. The purification of water and aqueous solutions from heavy metal ions is carried out in an electrolytic cell made of alternating three steel and three titanium electrodes. Electrode materials: stainless steel 12X18H10T, titanium alloy OT4-0. The volume of the filled solution is 50 ml; temperature 20-25 ° C: distance between the plates 5-7 mm; electrolysis is carried out at a current density of 16-17 A / dm2.
Содержание ионов металлов в растворе после электролиза контролируют химическимThe content of metal ions in the solution after electrolysis is controlled by chemical
методом и.фотокалориметром Ф-106. Наличие ионов металлов не обнаружено.using the F-106 photo calorimeter method. The presence of metal ions is not detected.
Результаты экспериментов представлены в таблице.The results of the experiments are presented in the table.
Провод т эксперименты с различным сочетанием материала электродов: графит-графит , графит - сталь (12Х18Н10Т), графит - титановый сплав (ОТ4-0), титановый сплав - титановый сплав ОТ4-0-ОТ4-0, алюминий - медь; алюминий,- титановый сплав (ОТ4-0); медь - сталь - (12X18Н10Т). Степень очистки сточной воды не улучшаетс .Conducted experiments with various combinations of electrode material: graphite-graphite, graphite - steel (12X18H10T), graphite - titanium alloy (OT4-0), titanium alloy - titanium alloy OT4-0-OT4-0, aluminum - copper; aluminum, - titanium alloy (OT4-0); copper - steel - (12X18H10T). The degree of wastewater treatment is not improved.
