| dc.description.abstract | The hydrolysis of pyrophosphate was investigated at different concentrations (2X10~3 M, 4X10~3 M and 1(f2 M) of [N4CO(OH)(OH ))2+ [N. = en2 and tn^ ten = ethylenddiamine, tn = trimathylenediamine)] 2+ + ' - using Eu /H and OH quenching techniques. The reaction was inonitored by measurement of orthophosphate (pi) in quenched aliquots of the reaction mixtures using Malachite Green phosphornolybdate complex as the analytical reagent. The reactive species with regard III to hydrolysis was found to be a 3:1 N^Co ppi complex. The results show a relatively larger amounts of degradation products for the directly added systems than for those mixed by step wise addition. Factors affecting the formation and degradation of the reactive species are discussed and plausible mechanisms are forwarded | en_US |
