COMPLEXING ABILITY OF PESTICIDES AND RELATED-COMPOUNDS - FORMATION AND STABILITY OF THE COMPLEX SPECIES OF 3-AMINO-1,2,4-TRIAZOLE AND ACETATE, MALONATE OR CITRATE IN AQUEOUS-SOLUTION

Formation and stability of complex species deriving from interaction b etween 3-amino-1,2,4-triazole [H(ata)] with acetate, malonate and citr ate, has been studied in aqueous solution, by potentiometric method [( H+)-glass electrode] at T = 25-degrees-C. Experimental data are consis tent with the formation of (ata)LH(j) species (j = 1...n + 1, n = numb er of protons in the carboxylic acid, H(j)L). The stability of the hyp othesized species is discussed, in relation to speciation problems in natural waters.
