摘要：
Complexes of three grades of sodium carboxymethyl cellulose (CMC) with cobalt(II) chloride have been prepared and characterized by elemental analysis, magnetic measurements, and infrared (IR) and electronic spectroscopy. The studies revealed that CMCs react with cobalt(II) in the stoichiometric ratio 1:1 (metal ion:ligand). The ligand field parameters of the octahedral Co(II) complexes were calculated. The stability of these complexes was studied in DMF medium using spectrophotometric methods. The optimum conditions favoring complex formation are critically evaluated.
