Abstract

Colour reaction of 2-(H-acidazo)-4,5-dinitrophenol(HADNP) with aluminium was studied.In pH5.3 (CH 2) 6N 4-HCl buffer solution,HADNP can react with Al 3+ to form a 3∶1 stable complex.The molar absorptivity is 3.29×10 4 L·mol -1 ·cm -1 at 570?nm.Beer's law is obeyed in the range of 0～480?μg·L -1 .This method can be applied to the determination of aluminium in water with satisfactory results.
