Description
Изобретение откоситс к цветной металлургии и может быть использовано дл электролитического получени кадми из сульфатных растворов.The invention tends to non-ferrous metallurgy and can be used for the electrolytic production of cadmium from sulphate solutions.
Целью изобретени вл етс улучшение качества осадка за счет его компактности и снижение расхода реагента .The aim of the invention is to improve the quality of the sludge due to its compactness and reduction of reagent consumption.
Пример. Электроосаждение кадми провод т из искусртвенных водных сульфатных растворов по предлагаемому способу. Дл экспериментов используют раствор следующего состава, г/дм : кадмий 55, серЬа кислота ПО температура электролита 25-30 С,ка- тодна плотность тока 55 А/м длительность наращивани осадка 24 ч, В качестве электродов используют дл катодов алюминий, а дп анодов - свинцово-серебр ный (1%) сплав.По- лиакриламид добавл ют в количестве, мг/л: 0,04; 0,1; 0,6; 1,0; 1,1.Example. Electrodeposition of cadmium is carried out from artifical aqueous sulphate solutions according to the proposed method. For the experiments, a solution of the following composition was used, g / dm: cadmium 55, serba acid, electrolyte temperature 25–30 ° C, cathode current density 55 a / m duration of sediment buildup 24 hours, aluminum used as electrodes, and dp anodes - lead-silver (1%) alloy. Polyacrylamide is added in the amount, mg / l: 0.04; 0.1; 0.6; 1.0; 1.1.
Дл сравнени провод т электроосаждение кадми из аналогичного раствора в присутствии силиката натри .For comparison, cadmium is electroplated from a similar solution in the presence of sodium silicate.

В процессе экспериментов контролируют силу тока, кислотность, теи- пературу электрогчта, замер ют напр жение на ванне, провод т расчет выхода ка;др-ш по току и определ ют расход электроэнергии.In the course of the experiments, the current intensity, acidity, and the temperature response of the electrohist are monitored, the voltage on the bath is measured, the output is calculated; others are measured by current, and the power consumption is determined.
Катодный кадмий анализируют на свинце. Результаты лабораторных испытаний представлены в таблице.Cathodic cadmium is analyzed on lead. The results of laboratory tests are presented in the table.
Из данных таблицы следует, что поставленна цель - получение компактного катодного осадка кадми (ровный, плотный, без дендритов) и снижение расхода реагентов достигаетс при введении полиакриламида в качестве ПАВ в процессе электролиза кадми в пределах 0,1-1,0 мг/л. При этом выход кадми по току составл ет 87-88% и расход электроэнергии 1350 - 400 КВТ.ч/т.From the data in the table it follows that the goal is to obtain a compact cathode sediment of cadmium (smooth, dense, without dendrites) and a reduction in the consumption of reagents is achieved by introducing polyacrylamide as a surfactant during cadmium electrolysis in the range of 0.1-1.0 mg / l. In this case, the cadmium yield per current is 87-88% and the power consumption is 1350 - 400 KWh / t.
Преимущество предлагаемого способа в сравнении с известным заключаетс в снижении расхода примен емого реагента в 8-10 раз, а также получение компактного, плотного без дендритов осадка.The advantage of the proposed method in comparison with the known method is in reducing the consumption of the reagent used by 8-10 times, as well as obtaining a compact, dense sediment without dendrites.
