Abstract
Inventia se refera la un procedeu de separare a albastrului de Berlin din deseurile formate in rezultatul demetalizarii vinurilor cu hexacianoferat(II) de potasiu si poate fi utilizata in industria vinicola, la producerea sucurilor si in tehnologia de producere a acidului tartric.Procedeul include diluarea deseurilor cu apa de 2…4 ori, introducerea clorurii de sodiu si a substantei tensioactive in urmatorul raport al componentilor, in g/l:clorura de sodiu 3,00…5,00substanta tensioactiva 0,01…0,05,tratarea lor intr-un electroflotator cu spuma cu anod de grafit si catod punctiform la densitateacurentului catodic de 1…5 A/dm2, cu separarea ulterioara a precipitatului din suspensia apoasa si purificarea lui prin filtrarea si recristalizarea albastrului de Berlin. Totodata, in calitate de substanta tensioactiva poate fi utilizata sarea de sodiu a acizilor grasi superiori, iar recristalizarea albastrului de Berlin din precipitat se produceprin prelucrarea cu hidroxid de sodiu pana la transformarea lui in forma solubila in apa, filtrareasi separarea in solutie acida de sulfat de fier(III).Rezultatul consta in majorarea eficacitatii extragerii cianidelor din deseuri, precum si in micsorarea volumului de munca.The invention relates to a process for separating the blue from Berlin from the wastes formed as a result of the demetallization of wines with potassium hexacyanoferate (II) and can be used in the wine industry, in the production of juices and in the technology of production of tartaric acid. The process includes dilution of wastes with water 2 ... 4 times, the introduction of sodium chloride and surfactant in the following ratio of the components, in g / l: sodium chloride 3.00 ... 5.00 surfactant 0.01 ... 0.05, treating them in a foam electroflot with graphite anode and a point cathode at the cathodic current density of 1 ... 5 A / dm2, with the subsequent separation of the precipitate from the aqueous suspension and its purification by filtering and recrystallizing the Berlin blue. At the same time, as a surfactant the sodium salt of the higher fatty acids can be used, and the recrystallization of the Berlin blue from the precipitate will be processed by processing with sodium hydroxide until it is transformed into a water soluble form, filtering the separation into acid sulphate solution. iron (III). The result consists in increasing the efficiency of cyanide extraction from waste, as well as in reducing the volume of work.
