Název v původním jazyce

The influence of calcium dihydrogen phosphate upon Kola apatite decomposition by orthophosphoric acid

Popis výsledku v původním jazyce

The decomposition of phosphates by orthophosphoric acid has a great importance in manufacturing of phosphoric fertilizers. This process is an initial technological operation during which water-insoluble form of phosphorus is converted into a water-soluble form, which is assimilable for plants. This work deals with a study of product calcium dihydrogen phosphate upon Kola apatite decomposition by orthophosphoric acid. It is reaction between solid and liquid phase, which is controlled in a way that all formation products are dissolved in system. All experiments were carried out in the batch isothermal stirred reactor for the initial phase of the decomposition with narrow fraction of apatite Kola super particles. Orthophosphoric acid with dissolved calcium dihydrogen phosphate was used in a great excess. The course of the decomposition was observed by weighing of the non-reacted residual of the apatite after termination of the reaction. The dependencies of conversion degree on the time re
