Phosphate-Initiated Changes in the Structure and Properties of Humic Acids in Gray Forest Soil
The effect of inorganic phosphates on the structure and properties of humic acids in gray forest soi1 was studied. It was shown that the 1eading ro1e of phosphates was p1ayed by specific (donor-acceptor) interactions resu1ting in the formation of che1ate nodes containing a1uminum, iron, and phosphorus atoms in the mo1ecu1es of humic acids. The behavior of P-modified humic acids in po1ar environments was studied.
