(54) СПОСОБ ИЗВЛЕЧЕНИЯ МЫШЬЯКА ИЗ КИСЛЫХ РАСТВОРСВ(54) A METHOD FOR EXTRACTING A BRAIN FROM ACIDIC MIXTURES
Изобретение относитс к способам экстракционного извлечени мышь ка и может использоватьс в аналитической химии. Известен способ извлечени мышь ка из кислых растворов с рН 1,0-2,0 путем экстракции его органическими монокарбоновыми кислотами в присутствии больших количеств железа. Однако степень извлечени мышь ка не достаточно высока - 90--95% 1. Известен taкжe способ извлечени мышь ка из кислых растворов с рН 4-6 путем экстракции его органическим растворителем-хлороформом в присутствии металлорганического соединени - гидроокиси трифенилсвинца. При этом в процессе извлечени мышь ка необходимо строго поддерживать рН раствора равным 4-6, так как при изменении рН резко уменьшаетс степень экстракции; кроме того, примен емый экстрагент довит 2. Цель изобретени - обеспечить извлечение мышь ка при рН раствора 0,3-6 и повысить безопасность процесса. Это достигаетс предложенным способом извлечени мышь ка из кислых растворов, заключающимс в экстракции его органичесКИМ растворителем в смеси с солюбилизируюшей добавкой, вз той в количестве 5-30 об.%, и в использовании в качестве металлорганического соединени динитрата динонилолова при концентрации его в растворе 0,005-0,1 М. Предпочтительным вл етс использование в качестве органического раство,рител не смец1иваюш,ихс с водой ароматических или алифатических углеводородов или их галоидпроизводных, кетонов , высокомолекул рных спиртов, простых и сложных эфиров. в качестве солюбилизирующей добавки используют органические фосфаты или фосфинокиси , высокомолекул рные спирты. Предложенный способ позвол ет извлекать мышь к из растворов с рН 0,3-6 li повысить безопасность процесса, так как примен емый экстрагент мало токсичен. Пример 1. К 50 мл воды с рН 6, содержаш .ей мышь к (V), добавл ют 50 мл 0,1 М раствора динитрата динопилолова (ДНДНО) в хлорофор.ме с 25% трибутилфосфата (ТБФ) и экстрагируют 10 мин. Фазы раздел ют. Процент извлечени мышь ка (V) в органическую фазу составл ет 99,9%Пример 2. К 50 мл водного раствора с рН 2, содержащего М мышь ка (V), добавл ют 50 мл 0,1 М раствора ДНДНО в хлороформе с 30% бутилового спирта и экстрагируют мышь к 10 мин. Процент извлечени мышь ка составл ет 99,3-99,7%.The invention relates to methods for the extraction of arsenic and can be used in analytical chemistry. A known method of extracting arsenic from acidic solutions with a pH of 1.0-2.0 by extracting it with organic monocarboxylic acids in the presence of large amounts of iron. However, the recovery rate of the mouse is not high enough - 90--95% 1. Also known is the method of extracting the mouse from acidic solutions with pH 4-6 by extracting it with organic solvent-chloroform in the presence of an organometallic compound, triphenyl lead hydroxide. At the same time, in the process of removing the mouse, it is necessary to strictly maintain the pH of the solution equal to 4-6, since the degree of extraction decreases sharply with a change in pH; In addition, the extractant used is added 2. The purpose of the invention is to ensure the removal of the mouse at a pH of 0.3-6 and to increase the process safety. This is achieved by the proposed method of removing the mouse from acidic solutions, consisting in extracting it with an organic solvent in a mixture with a solubilizing additive, taken in an amount of 5-30% by volume, and using dinonyl tin dinitrate as the organometallic compound at a concentration of 0.005- 0.1 M. It is preferable to use aromatic or aliphatic hydrocarbons or their halogen derivatives, ketones, high molecular pirates, ethers and esters. Organic phosphates or phosphinoxides, high molecular weight alcohols, are used as a solubilizing additive. The proposed method allows the mouse to be removed from solutions with a pH of 0.3-6 li to increase the safety of the process, since the extractant used is not very toxic. Example 1. To 50 ml of water with a pH of 6, containing mouse (V), add 50 ml of a 0.1 M solution of dinopyl dinitrate (DNDNO) in chloroform with 25% tributyl phosphate (TBP) and extract for 10 minutes. The phases are separated. The percentage of extraction of the mouse (V) into the organic phase is 99.9%. Example 2. To 50 ml of an aqueous solution with pH 2 containing M mouse (V), add 50 ml of a 0.1 M solution of DNDNO in chloroform with 30 % butyl alcohol and extracted the mouse for 10 minutes The recovery percentage of the mouse is 99.3-99.7%.
Пример 3. К 5Q мл водного раствора с рН б, содержащего 10 М мыщь ка (V), добавл ют 50 мл 0,1 М раствора ДНДНО в толуоле с 10% смеси спиртов CY-€9, фазы перемешивают 10 мин и затем раздел ют. Процент извлечени мышь ка (V) составл ет 99,6-99,7%.Example 3. To 5Q ml of an aqueous solution with pH b, containing 10 M bristle (V), add 50 ml of a 0.1 M solution of DNDNO in toluene with a 10% mixture of CY- alcohols of € 9, the phases are stirred for 10 minutes and then partitioned yut. The recovery percentage of mouse (V) is 99.6-99.7%.
Таким же сцособом можно очищать воду и водные растворы кислот, использу в качестве экстрагента 0,1 М растворы ДНДНО в хлороформе с 10% спиртов Су-Сд, в керосине с 25% ТБФ или 20% спиртов , в дихлорэтане с 25% ТБФ или 10% смеси спиртов Су--09, в метилизобутилкетоне , в бутилацетате. Степень извлечени мышь ка 99,5-99,In the same way, water and aqueous solutions of acids can be purified using 0.1 M DNDNO solutions in chloroform with 10% Cycd alcohols, in kerosene with 25% TBP or 20% alcohols, in dichloroethane with 25% TBP or 10 % of a mixture of alcohols Su - 09, in methyl isobutyl ketone, in butyl acetate. The recovery rate of mouse is 99.5-99,
Пример 4. К 50 мл 0,78 М раствора ванади в 2 W. HNOj, содержащего мышь к, добавл ют 50 мл 0,1 М раствора ДНДНО в хлороформе с 30% бутилового спирта и экстрагируют 10 мин. Фазы раздел ют. Степень извлечени мышь ка 99,0%.Example 4. To 50 ml of a 0.78 M solution of vanadium in 2 W. HNOj containing mouse, 50 ml of a 0.1 M solution of DNDS in chloroform with 30% butyl alcohol are added and extracted for 10 minutes. The phases are separated. The recovery rate of the mouse was 99.0%.
