Studying the composition of complex mineral fertilizers and inorganic salts in accordance with international REACH requirements

Abstract The qualitative and quantitative composition of chemical substances, entering in the complement of products of enterprise such as technical fluoride of aluminum, artificial technical cryolite, waterless sulfite of sodium, NPK-complex fertilizers of brands (10:19:25), (16:16:16), 7:16:31 (B), ammoniated superphosphate, ammophos, and also bulk blending fertilizers, containing ammonia nitrate as the nitrogen component, is defined. Chemical, phase, quantitative and mineralogical composition of products are set and specified, physical, structural-mechanical and physical-chemical properties of products are studied with the use of methods of X-ray analysis, IR spectroscopy, thermal, electronic-microscopic, grain-size, mass spectroscopic analyses and also calculations of balances on separate cations and anions taking into account their charges.
