Analysis of Aluminium:

In the second method including use of 8-hydroxyquinoline complex, aluminium tris (8-hydroxyquinoline) is acquired at pH 6.7. The complex is extracted along with chloroform and has excitation maxima at 350 nm although emission wavelength is 520 nm. Only gallium displays interference in this method and the sensitivity is of the order of 0.1µg / ml.

A structures of morin and 8-hydroxyquinoline as the common fluorinating agents are given below.
