Description
нос т в мерную колбу 50 мл, довод т водой до метки, перемешивают (раствор А).50 ml are put into a volumetric flask, made up to the mark with water, stirred (solution A).
Через 20 мин отфильтровывают 10 мл раствора А в мериую колбу 50 мл, ириливают 30 мл воды и 5 мл 1н. хлорида аммони + + 1н, аммиака, водой уровень раствора довод т до метки, перемешивают, пропускают азот и фиксируют пол рограммы меди и никел .After 20 minutes, 10 ml of solution A is filtered off into a 50 ml measuring flask, and 30 ml of water and 5 ml of 1N are poured. ammonium chloride + 1N, ammonia, water level is adjusted to the mark, stirred, nitrogen is passed and the copper and nickel programs are fixed.
К 25 мл раствора А прибавл ют 2 г хлорида аммопи , 5 г однозамещенного фосфата натри и аммиак до рН 6-7, осадок оставл ют на 20-30 мин, переиос т раствор с осадком в мерную колбу 50 Л1Л, прибавл ют 1 мл %-ного спиртового раствора диметилглиоксима , уровень раствора водой повышают до метки, перемешивают, отфильтровывают 35 мл раствора в сосуд дл пропускани азота, добавл ют 5-6 капель аммиакаTo 25 ml of solution A were added 2 g of ammopi chloride, 5 g of sodium phosphate monosubstituted and ammonia to pH 6-7, the precipitate was left for 20-30 min, the solution with sediment was re-converted into a 50 L1L volumetric flask, 1 ml was added a dimethylglyoxime alcohol solution, the solution level is raised to the mark with water, stirred, 35 ml of the solution is filtered into a vessel for passing nitrogen, 5-6 drops of ammonia are added
до рН 8-9, пропускают азот и пол рографируют . Расчет провод т методом добавок.until pH 8–9, nitrogen is passed and polished. The calculation is carried out by the addition method.
