Description

Известные химические методы определени  содержани  металлического железа не применимы дл  определени  его в окисленных и карбонатных марганцевых рудах, а также в породах, содержащих двуокись марганца или карбонат железа.The known chemical methods for determining the content of metallic iron are not applicable for its determination in oxidized and carbonate manganese ores, as well as in rocks containing manganese dioxide or iron carbonate.

Предлагаемый метод определени  содержани  металлического железа в пробах марганцевых руд, в материалах, содержащих свободную окись кальци , и в железных порошках основан на извлечении железа путем нагревани  пробы в растворе хлорной ртути в метиловом спирте в присутствии салицилово-кислого натри . Количество железа определ ют кдлориметрически в отфильтрованном растворе по бурой окраске его соединени  с сульфосалициловой кислотой, образующегос  при рН 4,5-7,0 (ацетатный буфер).The proposed method for determining the metallic iron content in manganese ore samples, in materials containing free calcium oxide, and in iron powders is based on the extraction of iron by heating the sample in a solution of mercuric chloride in methyl alcohol in the presence of salicylic acid sodium. The amount of iron is determined by a chlorimetric in a filtered solution from the brown color of its compound with sulfosalicylic acid, formed at pH 4.5-7.0 (acetate buffer).

Предлагаемый метод позвол ет определ ть содержание металлического железа не только в присутствии двуокиси марганца, но и других окислителей, как, например, V2O5, и .The proposed method allows the determination of metallic iron content not only in the presence of manganese dioxide, but also other oxidizing agents, such as V2O5, and.

Навеску 0,500-1,00 г пробы помещают в сухую коническую колбу емкостью 50-100 мл, приливают 20 мл раствора хлорной ртути и салициловокислого натри  в метиловом спирте и нагревают при слабом кипении в течение 10 мин., часто перемешива . После охлаждени  содержимое колбы перевод т в мерную колбу на 100,0 мл, обливают первую водой, не добива сь полного сливани  руды, разбавл ют до метки и пе .ремещивают. После отсто , фильтруют через сухой фильтр в сухой сосуд , отбросив первые 10-15 мл фильтра. От прозрачного раствора отбирают в мерную колбу на 100,0 мл аликвотную часть с таким расчетом, чтобы содержание железа в ней было меньще 1 мг, прибавл ют три капли сол ной кислоты 1 :2 и перемешивают. Затем приливают 10 мл ра№ 123949A sample of 0.500-1.00 g of the sample is placed in a dry conical flask with a capacity of 50-100 ml, 20 ml of a solution of chlorine mercury and sodium salicylic acid in methyl alcohol are poured in and heated at a low boil for 10 minutes, often stirring. After cooling, the contents of the flask are transferred into a 100.0 ml volumetric flask, the first is poured with water, without complete discharge of the ore, diluted to the mark and re-displaced. After settling, filter through a dry filter into a dry vessel, discarding the first 10-15 ml of filter. From a clear solution, a 100.0 ml aliquot is taken into a volumetric flask so that its iron content is less than 1 mg, three drops of hydrochloric acid 1: 2 are added and mixed. Then poured 10 ml of p. Number 123949

Интенсивность окраски комплексного соединени  железа с сульфосалициловой кислотой измер ют на фотоколориметре с синим светофильтром , а содержание железа в пробах наход т ло калибровочномуThe intensity of the color of the complex compound of iron with sulfosalicylic acid is measured on a photocolorimeter with a blue filter, and the iron content in the samples was calibrated.

Дл  построени  калибровочного графика паралле тьно с пробами через все операции анализа провод т холостые пробы, от которых отбирают аликвотные части, такие же как и от проб, и добавл ют к ним соответствующее количество стандартного раствора железа.To build a calibration graph in parallel with samples, blank samples are taken through all analysis operations, from which aliquots are taken, the same as from samples, and an appropriate amount of standard iron solution is added to them.
