STUDIES ON THE RELATIONSHIP BETWEEN THE STRUCTURAL FACTORS OF ORGANIC COMPLEXING AGENTS AND THEIR ENHANCEMENT EFFECT OF ATOMIC ABSORPTION SPECTRA WITH HUCKEL MOLECULES ORBITAL METHOD
Abstract：The quantum chemistry parameters of 14 organic complexing agents molecules were calculated with HMO method. Accoring to the charge density of the frontier atoms and the bond order between the frontier atom and its neighbourhood atom, the enhancement effect of organic eomplexing agents on atomic absorption spectrophotometric analysis of ytterbium element is discussed. It is shown that there are relationships between absorbance and charge density Q, bond orderp, respectively. And the starting pH of enhancement pHs related to the ionization constants of organic complexing agents.
