Use of nitriletris(methylphosphonic acid) as complexing agent of manganese ions in fertilizer systems
A complexation of Mn ions with nitriletris(methylphosphonic acid) was carried out by polarog. (differential pulse voltammetry). Samples with molar ratios of metal to ligand 1:1 or 2:1 were analyzed in N, N-P and N-P-K fertilizing environment and at various pH range. The high degree of Mn ions complexation (98%) was achieved in the N-P-K fertilizing environment at pH 7 and for the metal:ligand molar ratio of 2:1.
