Paper Title:
Sensitive Spectrophotometric Method for Determination of Trace Aluminium in Water Samples by Morin
  Abstract

The chromogenic reaction of Al (III) with morin was studied in the presence of cationic surfactant cetyltrimethylammonium bromide(CTMAB), Al (III) was capable of reacting with morin to form a stable yellow complex in 0.17 mol l-1 glacial acetic acid media. The complex had a 1∶2 molar ratio for Al (III) and morin . In the presence of cationic surfactant CTMAB, the sensitivity of chromogenic reaction was largely improved. At the maximum absorption wavelength of 425nm, the apparent molar absorptivity was 1. 59×105l·mol - 1·cm- 1 .Beer′s law was obeyed in the range of 0 to 8μg/ 25ml Al (III) . The method has been applied successfully to the determination of trace amount of aluminium in tap and river water samples.
