Description
Известные способы количественного определени никел (по Чугаеву , электролитическое определение, с применением цианистых солей и др.) трудоемки, сложны итреб ют дорогосто щих реактивов и приборов .Known methods for the quantitative determination of nickel (according to Chugaev, electrolytic determination using cyanide salts, etc.) are laborious, complicated, and require expensive reagents and instruments.
Предлагаемый арсенатный снособ иодометрического определени никел , осмоиан па свойстве никел давать нерастворимые соли с ортомыи ь ко1;о1 1 кислотой и па способности мыш1 ковО 1 кислоты окисл ть иодиды в свободный иод. Способ устран ет указанные недостатки известных способов и Д;ает возможность в отсутствии меди и цинка количествеипо определ ть никель с меиьшеи затратой времени.The proposed arsenate method for the iodometric determination of nickel, the osmosis of the property of nickel to produce insoluble salts with ortomoly co1; o1 1 acid and the ability of micello1 acid to oxidize iodides into free iodine. The method eliminates the indicated disadvantages of the known methods and D; the possibility in the absence of copper and zinc to determine the amount of nickel with the least amount of time.
Оссбенг.ость предлагаемого способа заключаетс в том, что никель осаждают в тпзмсутствии хлорида и yK;- ciioir кислоты в виде двоГпюй соли iNH;AsO:, полученный осадок раствор ют в серпой кислоте с Г1ос. едующ 1. иодометрическнм определением мыц1 ковой кислоты в растворе.Ossbeng. The proposed method consists in the fact that nickel is precipitated in the presence of chloride and yK; - ciioir acid in the form of a double salt of iNH; AsO: the precipitate is dissolved in sickle acid with G1oc. Going through 1. Iodometric determination of mycic acid in solution.
П р н м е р. Навеску соли никел (из расчета приготовлени 100 см 1,С-0,1 nojiMa.ibHoro раствора) раствор ют в воде и.ти серной ки лоте, на холоду НЛП при иагрева.нии. К Ш мл приготовлеииого раствора прибавл ют ла холоду 1-2 г Хлористого аммони , 1 иы cepHoii кислоты (если иавеска растворена в воде) и п тикратньп нзбыток мышь KOBoit К11С.ЛОТЫ. Раствор нагревают до кипени и добавл ют по капл м 15)-iibiir гидрат аммони до по влени обильного осадка, который раствор ют п избытке 30%-пой укс сиой кислоты.PREMIER A portion of the nickel salt (based on the preparation of 100 cm 1, C-0.1 nojiMa.ibHoro solution) is dissolved in water and in sulfuric acid, in the cold of NLP during heating. 1-2 ml of ammonium chloride, 1 of cepHoii acid (if dissolved in water) and five-fold KOBoit K11.Loty mouse are added to cold ml of the prepared solution. The solution is heated to boiling and 15) -iibiir ammonium hydrate is added dropwise until a copious precipitate is formed, which is dissolved in an excess of 30% acetic acid.
i 1о;1учен. раствор кип т т в течсиие 15-20 мин. до исчезновени запаха уксусной кислоты, затем сиова добавл ют несколько капель гидрата a.;oии (до по влени запаха аммиака) и кип т т 10 мин., после, чего раствор фильтруют в гор чем состо иии через двойной бензольный фильтр. Осадок декаитируют г;;р чеП водой 10 мии.i 1o; 1uchen. the solution is boiled for 15–20 min. until the smell of acetic acid disappears, then siova is added a few drops of hydrate a.; o (until the smell of ammonia appears) and boiled for 10 minutes, after which the solution is filtered in a hot state through a double benzene filter. The precipitate is decayed with r ;; r water with 10 missions.
Промытый осадок раствор ют в 25--50 мл теплой серной кислоты (1:2,5). К пглучглпюму раствору прм комнатиой температуре добавл ютThe washed precipitate is dissolved in 25--50 ml of warm sulfuric acid (1: 2.5). To the solution of the solution at the right temperature is added
