Предмет изобретени  Способ количественного определени  никел  колориметрическим путем с применением органических реактивов, о т л и ч а ю ni, и и с   тем,. что в качестве органического реактива примен ют бис (2-окси-тиобензоил ) дисульфид.P r and m er. To 1 ml of a solution containing 1-5t (g 0.001 g) of nickel and no more than 2 lg of Fe in a test tube using a colorless glass, pour 1 ml of a 10% solution of ammonium chloride and 0.5 | ammonia solution (pH 7.6-7.8), the argument of the solution to 5 ml. Then, a 1 ml solution of a 0.006 solution of bis (2-hydroxytobeisoyl) disulfide in beisole is added and shaken for 1-2 minutes. At the same time, a preparation of standard solutions is prepared. To do this, in five of the same probprok are entered, respectively, 0.5 y; 1.0 2.0; 4.0 7 and 5.0 7 nickel in solution, 1 ml of 0% ammonium chloride solution, 2 ml of saturated sodium fluoride solution, 0.5 ml of ammonia solution, 2 ml of 0.005% bis solution thiobeneol) disulfide and shake for 1-2. Results are obtained using colorimetric determinations. The subject of the invention. A method for quantitative determination of nickel by a colorimetric method using organic reagents, that is, and with that. that bis (2-hydroxy-thiobenzoyl) disulfide is used as an organic reagent.
