На чертеже представлена зависимость комплексообразовани полидиме- типдиаллиламмонийхлорида с феррициа- нидом кали от рН и концентрации КОН в растворе (относительное среднеквадратичное отклонение определени не более 0,04).The drawing shows the dependence of the complexation of polydimetryptale di-allyl ammonium chloride with potassium ferricyanide on pH and KOH concentration in solution (relative standard deviation of the determination is not more than 0.04).
Пример 1. К 5%-ной суспензии глины добавл ют полидиметилдиал- лиламмонийхлорид до его концентрации в растворе 0,5%. Из водного отсто бурового раствора отбирают 0,5 мл и разбавл ют водой до 50 мл. Аликвот- ную часть раствора 1,5 мл перенос т в чейку дл титровани и довод т рН до 0,5. Общий объем исследуемого раствора 16 мл. Титруют на амперомет- рической установке с платиновым и хлорсеребр нным элек тродами,прибавл 0,01%-ный феррицианид кали по 0,05 мл при перемешивании. Напр жение в чейке 0,1 В. Объем титранта, пошедший на титрование, наход т по точке эквивалентности на кривой титровани . Концентрацию полимера в растворе определ ют по градуировочной кривой . Концентраци полимера в растворе после адсорбции 0,36%.Example 1. Polydimethyldiallyl ammonium chloride is added to a 5% suspension of clay to its concentration in a solution of 0.5%. 0.5 ml is withdrawn from the aqueous sludge mud and diluted with water to 50 ml. A 1.5 ml aliquot of the solution is transferred to a titration cell and the pH is adjusted to 0.5. The total volume of the test solution is 16 ml. Titrated on an amperometric unit with platinum and chlorine-silver electrodes, added 0.01% potassium ferricyanide 0.05 ml with stirring. The voltage in the cell is 0.1 V. The volume of titrant that went to titration is found at the equivalence point on the titration curve. The concentration of the polymer in the solution is determined by a calibration curve. The polymer concentration in the solution after adsorption is 0.36%.
