Aluminum forms a 1:1 complex with 2-hydroxy-l·naphthaldehyde p-methoxyhenzovlhvdraxonal. which absorbs UV radiation at 285 nm. Under pseudo-first order conditions, a plot of the initial rate of the reaction (absorbance units per second) versus the concentration of aluminum (in μM)yields a straight line described by the equation
