Документ Investigation of reactions for processing of sugar-juice defecation sludge on oxide materials and fertilizers(2016) Perepelitsa, Alexander; Petrenko, Tetiana; Samchuk, AnatoliyAt first, reactions of defecate of sugar production with acid oxides MoO3, WO3 (І) and phosphate acid H3PO4 (ІІ) were investigated with methods of chemical analysis, pH-measuring, thermogravimeasuring and X-rays. In the system (I) separate phases with tetragonal syngony are forming, while in the system (II) the mixture of Са3(РО4)2, СаНРО4 and Са(Н2РО4)2 are precipitating. These products can be used as inorganic oxide materials and fertilizers or forages addings for agriculture. Вперше методами хімічного аналізу, рН-метрії, термогравіметрії і рентгенографічно досліджено реакції дефекату цукрового виробництва з кислотними оксидами MoO3, WO3 (І) та фосфатною кислотою H3PO4 (ІІ). В системі (І) утворюються індивідуальні фази з тетрагональною сингонією, тоді як у системі (ІІ) осаджується суміш Са3(РО4)2, СаНРО4 і Са(Н2РО4)2. Ці продукти можуть бути використані як оксидні неорганічні матеріали і добрива або кормові добавки для сільського господарства.Документ Study of bishofite-phosphate acid interaction in the aqueous solution(2016) Perepelitsa, Alexander; Petrenko, Tetiana; Samchuk, Anatoliy; Semenenko, M. P.; Khomenko, BorysBy methods of pH monitoring of filtration solutions as well as due to determinationof residual concentrations of ions Мg2+ and РО43- the bishofite–phosphate acid interaction was studied with the given ratio [РО43-]:[Мg2+]=0,187-5,24. The precipitation arising from the reaction was studied by chemical, thermal gravimetric and X-ray phase analysis and its compliance with the formula xNH4MgPO4∙yMgHPO4 was established, where х = 0,25; у = 0,75.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.
