A Chemometric Speciation Study of the Binary Ditopic Terephthalic Acid Dihydrazide and Divalent Metal Ion Systems in Aqueous Medium.
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 3
Abstract
Chemical speciation study of the interaction of Terephthalic acid dihydrazide with H+ , Mn2+ and Co2+ was carried out using a potentiometric method of data acquisition followed by chemometric modeling methods of analysis. The ligand possesses two hydrazide chelating units and is therefore able to form monometallic and bimetallic species in different protonated, unprotonated and deprotonated forms. Several species of the type MmLlHh (m=1or 2, l=1 or 2 and h varies from 4 to -1 depending on m and l) were observed to be present in solution. Concentration distribution diagrams were generated using the HYSS program.
