Abstract
Colorimetric analysis of Al in water according to the Eriochrome Cyanine R method has been studied. Absorbance measurement was carried out using a UV -VIS spectrophotometer. The absorbance reading can be obtained at λ.max = 535nm after a reaction time of 5 minutes. The relationship between absorbance and concentration obeyed the Beer-Lambert law at concentration range 0-1.0 µg/mL but showed a negative deviation at concentrations above 1.0 µg/mL. The presence of phosphate and ferric ions in solution produced a negative and positive interference, respectively, on the absorbance measurement. Analysis of river water and AMD samples showed Al concentrations in the range 0.3853 - 0.8241 µg/mL (average: 0.55 ± 0.01 µg/mL) and 117.74 - 181.95 µg/mL (average: 138.l6± 1.56 µg/mL), respectively.
