Abstract

Quinolinylazo) 1,5 Dihydroxidebenzen(QADHB)was synthesized and its color reaction with cobalt(Ⅱ) was studied. In the medium of PH 4.4 buffer solution and presence of CTMAB, QADHN reacted with cobalt(Ⅱ) to form a stable 2:1 complex. The molar absorptivity was at 580nm and Beer's law obeyed in the range of 0～15ug/25mL. The method could be applied to the determination of cobalt with satisfactory results.
