Description
Изобретение относитс к выделению ванади и может быть использовано дл извлечени его из нефти и нефтепродуктов .This invention relates to the isolation of vanadium and can be used to extract it from petroleum and petroleum products.
Целью изобретени вл етс повышение селективности извлечени и упрощение процесса.The aim of the invention is to increase the selectivity of extraction and simplify the process.
Пример, 25 мл раствора нефти, смешанной с толуолом, с концентрацией ванади 10 мкг/мл подают в анодную камеру двухкамерного электролизера с нерастворимыми графитовыми электродами, разделенными инертной ионообменной мембраной, со скоростью 25 мл/ч. Катодна камера не проточна и заполнена 15 мл 0,1 н. НС1, Электродиализ ведут при плотности переменного асимметричного тока 4 10 А/см2, частоте 47,5 Гц„ соотношении опорной.Example, 25 ml of an oil solution mixed with toluene with a vanadium concentration of 10 µg / ml is fed into the anode chamber of a two-chamber electrolyzer with insoluble graphite electrodes separated by an inert ion-exchange membrane at a rate of 25 ml / h. The cathode chamber is not flow through and is filled with 15 ml 0.1 n. HC1, Electrodialysis is carried out at a density of asymmetric alternating current of 4 10 A / cm2, frequency of 47.5 Hz "ratio of the reference.
и катодной плотности тока (ig/i) 1:9, Врем опыта 60 мин, температура 22°С. Раствор нефти, пропущенный через электролизер, упаривают до объема 5 мл и анализируют на содержание в нем ванади рентгенофлуоресцентным методом анализа. Водную фазу (0,1 н. НС1) отбирают, упаривают до объема 5 мл и также анализируют рентгенофлуоресцентным методом анализа на содержание в ней ванади .and cathode current density (ig / i) 1: 9, Test time 60 min, temperature 22 ° С. The oil solution passed through the electrolyzer is evaporated to a volume of 5 ml and analyzed for its content of vanadium using X-ray fluorescence analysis method. The aqueous phase (0.1 N. HC1) is taken, evaporated to a volume of 5 ml and also analyzed by x-ray fluorescence analysis method for the content of vanadium in it.
Результаты по извлечению ванади приведены в таблице.The results for vanadium extraction are shown in the table.
Расчеты показывают, что коэффициент разделени в системе ванадий - никель 141,8.Calculations show that the separation factor in the vanadium-nickel system is 141.8.
