摘要

A colorimetric procedure for the determination of trace quantities of cobalt(II) in the presence of the explosive cobalt(III) coordination compound 2-(5-cyanotetrazolato)pentaamminecobalt(III) perchlorate is described. Determinations were made at 693 nm in a solvent system consisting of 40 volume percent dimethyl sulfoxide and 7.2 molar hydrochloric acid. The system obeys Beer's law up to 60 mu gm Co(II)/mL of solution with a molar extinction coefficient of 626 1 mole exp -1 cm exp -1 . The Sandell sensitivity is 0.091 mu gm Co(II)/cm exp 2 for 0.001 absorbance. Molar extinction coefficients, at a fixed 7.2 molar hydrochloric acid content, were determined as a function of dimethyl sulfoxide concentration. The extinction coefficients at 40 volume % dimethyl sulfoxide are comparable to previously published cobalt(II) molar extinction coefficients obtained in 15 molal HCl. The procedure was used to help determine the extent of thermal decomposition of the cobalt(III) compound. (ERA citation 06:011304)
