Investigation of equilibrium in the system Mn-3-amino-1,2,4-trazole-H2O (Mnn+=Co,2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+, Ca3+, Al3+ and Fe3+)

Complexing of 3-amino-1,2,4-triazole (amitrole) in aqueous solutions at 20 deg C, pH 4-9 at ion force values of 0.1, 0.5 and 1.0 mol/hp with ions contained in soils as macrocomponents and microelements (Co2+, Cd2+, Hg2+) has been studied by the method of pH-metric titration. It is shown that in the environment and in living organisms amitrole forms strong enough complexes and its major part is in the bound state
