Документ Chemical composition and biological activity of compounds based on defecate(2015) Perepelitsa, Alexander; Ishchenko, Vera; Petrenko, TetianaInfluence of chemical contents from defecation mud-based mixtures with phosphate acid and defecation mud with bishofite saline solution on plants growth (rye, lentil) was researched in laboratory environment. Optimum concentrations of mud-based mixtures with phosphate acid and defecation mud with bishofite saline solution, promoting rye crops were identified. We have proven the possibility of artificial defecation mud mineralization in order to increase the effects of its positive influence towards plants growth.Документ Determination of trace elements (Cr, AI, Pb) by atomic absorption in natural water of Kyiv(2014) Polumbryk, Maksim; Ishchenko, Vera; Polumbryk, OlegThe control of microelements in water is a one of the most important factor of the humans health in urbanized cities. ETAAS method with chemical modifiers has been used in drinking water analysis.Документ Developing methodology for atomic absorption determination of metallic elements in natural water(2013) Ishchenko, Vera; Polumbryk, Oleg; Panchuk, TamaraInthispaper, we explore how macro component composition of natural waters impact atomization of chromium (Cr III, VI), lead (Pb) and aliminium (Al).It's been shown that the ascorbic acidis the optimal chemical modifier for electro ther mal determination of aluminiu mandlead, as wellas potassium chlorideis the one for chromium. Metrological characteristics of theme thodology have been tested on both models olutions and reals amples of natural and drinking waters.Документ Epidemio-surveillance of food-borne diseases and food safety(2015) Boyko, Anna; Ishchenko, Vera; Bylyna, AlexandrДокумент The calculation of the maximum rate of oxidation of nitrogen (II) oxide using the mathematical package MathCad(2017) Fatyeyeva, Anastasia; Ishchenko, Vera; Seidykh, OlgaIn this paper, the problem of calculating the maximum oxidation rate of nitric oxide is considered.
