Изобретение относитс  к способам измерени  концентрации веществ в многокомпонентных электропроводных растворах. Оно может быть использовано дл  определени  концентрации хлористого кали  в маточном и насыщенном щелоках калийных производствThis invention relates to methods for measuring the concentration of substances in multicomponent electrically conductive solutions. It can be used to determine the concentration of potassium chloride in the uterine and saturated liquors of potash production.

Известны способы определени  концентрации полезного компонента в многокомпонентных растворах путем измерени  электропроводности с применением разбавлени  1 . Недостатком известных способов  вл етс  низка  точность измерений, что объ сн етс  отсутствием однозначной зависимости между электропроводностью щелока и концентрацией в нем хлористого кали , т.е. при различных общих концентраци х солей крива  зависимости будет иметь различную форму,Methods are known for determining the concentration of the useful component in multicomponent solutions by measuring the electrical conductivity using dilution 1. A disadvantage of the known methods is the low accuracy of measurements, which is explained by the absence of an unambiguous relationship between the electrical conductivity of the liquor and the concentration of potassium chloride in it, i.e. with different total salt concentrations, the dependence curve will have a different shape,

Наиболее близким по технической сущности  вл етс  способ, который состоит в иэмерении электропроводности раствора, раэбавлении пробы, определении общей концентрации солей в растворе (2. Известный способ не устран ет вли ни  изменени  общей концентрации солей на точность измерени . The closest in technical essence is a method that consists in measuring the electrical conductivity of a solution, decreasing a sample, and determining the total concentration of salts in a solution (2. The known method does not eliminate the influence of a change in the total concentration of salts on the measurement accuracy.

Целью изобретени   вл етс  повышение точности измерени  концентрации хлористого кали , т.е. обеспечение линейной зависимости концентрации хлористого кали  от электропроводности .The aim of the invention is to improve the accuracy of measuring the concentration of potassium chloride, i.e. ensuring the linear dependence of the concentration of potassium chloride from the electrical conductivity.

Поставленна  цель достигаетс  тем, что пробу разбавл ют до 25%-ной концентрации солей в ней и замер ют электропроводность, по которой суд т о концентрации хлористого кали . В 25%-ном растворе электропроводность однозначна и линейно зависит от концентрации хлористого кали .This goal is achieved by diluting the sample to a 25% salt concentration in it and measuring the electrical conductivity, which is used to judge the concentration of potassium chloride. In a 25% solution, the conductivity is unambiguous and linearly dependent on the concentration of potassium chloride.

Пример. Одновременно отбирают две пробы щелока в количестве Р и Р„, первую пробу разбавл ют водой щэи по Example. At the same time, two samples of the liquor are taken in the amount of P and P ", the first sample is diluted with water
