Изобретение относитс  к технологии очистки от нримеси сульфат-ионов растворов нереkHCM водорода, примен емых дл  поглощени  двуокиси серы при определении содержани  Двуокиси серы в газах.This invention relates to a process for purifying sulfate ions from impurities of hydrogen hCM solutions used to absorb sulfur dioxide in determining the content of sulfur dioxide in gases.

Известеи способ удалени  примеси сульфат-ионов из растворов путем осаждени  Примеси в виде осадка нерастворимого соединени  сульфата бари .Limes A method for removing sulfate ion impurities from solutions by precipitation of the Impurity as a precipitate of an insoluble barium sulfate compound.

Недостатком известного способа  вл етс  необходимость введени  значительного избытка осадител , что делает невозможным применение указанного способа дл  очистки растворов перекиси водорода, пригодных дл  анал1иза двуокиси серы в газах, так как избыток ионов бари  будет мешать при иоследующем турбидиметрическом определении ионов сульфата, образующихс  при поглощении двуокиси серы из газов растворами окислителей , например перекиси водорода.The disadvantage of this method is the need to introduce a significant excess of precipitator, which makes it impossible to use this method for cleaning hydrogen peroxide solutions suitable for analyzing sulfur dioxide in gases, since an excess of barium ions will interfere with the subsequent turbidimetric determination of sulfate ions formed during the absorption of sulfur dioxide from gases with solutions of oxidizing agents, for example, hydrogen peroxide.

Дл  обеспечени  полноты осаждени  и удалени  из раствора избытка осадител , а также возможности очистки растворов иерекиси водорода, пригодных дл  поглощени  двуокиси серы при определении содержани  двуокиси серы в газах, предлагаетс  осажжение вести растворимой солью свинца, наЧIn order to ensure complete precipitation and removal of excess precipitant from the solution, as well as the possibility of purification of hydrogen ireoxide solutions suitable for absorbing sulfur dioxide when determining the content of sulfur dioxide in gases, it is proposed that the precipitation be carried out with a soluble lead salt,

пример нитратом свинца, а после отделени} осадка вводить комплексообразователь дли ионов свинца, например трилон Б.an example of lead nitrate, and after separating the precipitate} to introduce a complexing agent for lead ions, such as Trilon B.

По описываемому способу дл  очистки от сульфат-ионов k 1 л концентрированной перекиси водорода добавл ют 10 г нитрата свиица , через 2-3 час раствор отфильтровываюг от осадка сульфата свинца и в фильтрат добавл ют 12 г трилона Б. Дл  поглощени  двуокиси серы из газов используют 0,1 - 0,3%-ный раствор перекиси водорода.According to the described method, 10 g of lead nitrate are added to 1 l of concentrated hydrogen peroxide to purify sulfate ions, after 2-3 hours the filter solution is filtered from precipitate of lead sulfate and 12 g of trilon B are added to the filtrate to absorb sulfur dioxide from gases. 0.1 - 0.3% solution of hydrogen peroxide.

Предмет изобретени Subject invention

Способ удалени  примеси с льфат-иопов из растворов путем осаждени  npaiMecn в виде осадка нерастворимого соединени , отличающийс  тем, что, с целью обеспечени  полноты осаждени  и удалени  из раствора избытка осадител , а также возможности очистки растворов перекиси водорода, пригодных дл  поглощени  двуокиси серы при определении содержани  двуокиси серы в газах, осаждение ведут растворимой солью свинца, например нитратом свинца, а после отделени  осадка ввод т комплексообразователь дл  ионов свинца, например трнлон Б.The method of removing impurities from lophat-iops from solutions by precipitating npaiMecn as a precipitate of an insoluble compound, characterized in that, in order to ensure complete precipitation and removal from the solution of excess precipitant, as well as the ability to purify solutions of hydrogen peroxide suitable for absorbing sulfur dioxide when sulfur dioxide in gases, precipitation is carried out with soluble lead salt, for example lead nitrate, and after separating the precipitate, the complexing agent for lead ions is introduced, for example, trnlon B.
