The complex formation of bismuth with thiocyanate and basic dye 4-dimethilaminophenyl-4-methylbenzilaminophenyl-antypirylcarbonyl have been studied. The main chemical-analytical characteristics of ion par have been determined. The new method photometric determination of bismuth with thiocyanate and basic dye 4-dimethilaminophenyl-4-methylbenzilaminophenyl-antypirylcarbonyl is propose.

In the present work, the chemical analysis of the alloys and compounds of the ternary systems Pb(Hg) - Sb - O has been carried out. Mercury, Antimony and Oxygen was determined by the titrimetric methods, Mercury by the Volgard-method, Antimony by the bromatometry, and Oxygen by the acid-base titration. Lead has been determined using the atomic-absorption spectroscopy.

It was approbation of procedure of the determination of aluminum in food products and hade devotees what the procedure is an identical and serves for determinations of aluminum in food products, food raw materials and drinking water.

The aim of this work was study the content of heavy metals in the soils of Uzhhorod area. It was picked out 35 samples of soils and was determined using atom-emission spectroscopy the content of heavy metals, such as Cu, Pb, Cd, Ni, Zn, Mn. It was defined that the content of Zn, Cd, Mn are stays at the safety level. The contents of Cu, Pb, Cd in the soil exceeds of mission level.

The results of measurement of natural and artifical composition radioisotopes in the ground deposits of transkarpatian mountain districts small rivers by gamma-spectoscopy method are presented.

The efficacy of fertilizings made on a base of Sokyrnytsa zeolite (Transcarpathia, Ukraine) is researched and is exhibited, that most effective of them at cultivation of a potato is "Zeolityl" - the admixture of zeolite with a organic-mineral fertilizer. "Zeolityl" positively influences a contents in a soil of the relative frame forms of nutrient materials, assists intensive body height and development of a potato. Compared with other utilised fertilizings, "Zeolityl" provides the greatest accretion of productivity (0,81 ton/hectare), increases merchantability of yield (12 %) and average mass potatos and improves the qualitative indexes potatos.

The carried out comparative estimation of features of teaching of analytical chemistry behind credit-modular system ECTS at universities of some countries: Hungary (Debrecen university), Slovakia (Shafaryc University in Koshice), Ukraine (Ughorod national university). A number of problems is offered. Solving of them will permit to improve system of teaching of analytical chemistry.
