Abstract
The results of studying the processes of complex formation of N-benzyloyl-N'-(phenylsulfonyl)hydrazine (BPSH) with Cu(II) ions in ammonia media are presented. The complex formation reaction was studied by spectrophotometric method. The maximum light absorption of the studied complex compound was determined. The optimal conditions for the complex formation of BFSH with Cu(II) ions were studied: the time for the development of the color of the complex; pH range of complex formation, amount of photometric reagent. The optimal ratios [Cu(II)]:[BFSH]=2:1 and 1:1 were determined by the saturation method. Under optimal conditions, a calibration curve was constructed for the determination of Cu(II) ions with BFSH in an ammonia medium. Methods of mathematical statistics determined the convergence and correctness of the spectrophotometric method of determination. Approbation of the technique was carried out on the product of flotation enrichment of sulfide copper-nickel ore of the Murmansk deposit.
