Head Nadezda Antraptseva, Registration Date 04-04-2014 Organization National agricultural university of Ukraine popup.description2 A research object is the individual and double condensed phosphates of magnesium, manganes(ІІ), cobalt(ІІ), zinc. e Purpose of work - to probe the conduct of the condensed phosphates of magnesium, manganese (ІІ), cobalt(ІІ), zinc in standard agricultural chemistry solutions, imitating soil solutions. To set correlations between anionic composition of the individual and double condensed phosphates and properties, in particular, by solubility in water and citrate solutions. Research methods. For the receipt of the condensed phosphates used digidrofosfaty composition of Mg Mе (H PO ) 2H O (0<х<1,00), for heat treatment applied the dynamic (derivatograf Q-1500d, speed of heating a 2,5 degree in a min.) and isothermal modes. Authentication of polyforming was conducted by chemical and differential and thermal (derivatograf G 1500 D), methods of analysis. Anionic composition was determined, using a quantitative chromatography; solubility mono- and polyforming in water and citrate solutions - with the use of standard agricultural chemistry methods. Solubility of the individual linear and cyclic condensed phosphates of magnesium, manganese (ІІ), cobalt(ІІ), zinc in standard agricultural chemistry solutions is studied. Influence of nature of cation is set on solubility of the condensed phosphates in water and citrate solutions. Experimental information is got about solubility of the double condensed phosphates of magnesium, manganu (ІІ), cobalt(ІІ), to zinc with the different structure of anion in standard agricultural chemistry solutions. Quantitative correlations are set between the degree of polymerization of phosphatic anion and forconduct of the condensed phosphates in environments, imitating soil solution. Use area - the chemical industry, the agro-industrial enterprises, NRI NAN and NAAN of Ukraine.
