Study of a Copper Microelement Compound Formed in Ammophosis Pulp

The results of physicochemical analyzes the compound CuNH 4 PO ∙ H 2 O isolated from ammophos pulp at pH 6.58 obtained by neutralization phosphoric acid containing copper sulfate as a trace element with gaseous ammonia are presented. was found to have formula [Cu (NH 3 ) (H O) HPO ]. parameters N–H bond for coordinated amino group were calculated: force constant, angle, and interatomic distance. In transition electronic spectrum reflection hydrophosphate monohydrate ammonium phosphate monohydrate, hypochromic shift maximum 74 nm is observed, which indicates entry an molecule into composition monoaquahydrophosphate formation monoaquaaminehydrophosphate. This confirmed absence intense wide band 3100-2900 sm - 1 characteristic cation in IR spectrum.
