Iron in the extract was determined colorimetrically using orthophenanthrolein and aluminium by aluminon

The chelating agents employed vary depending on the target metals, and they include 2, 5-dimercapto-1, 3, 4-thiadiazole (18), ammonium pyrrolidine dithiocarbamate and its analog (19), dimethyiglyoxime (9, 21) and aluminon (22).

Most data on aluminum levels in wild plants are based on the aluminon test of Chenery (1948b), which is a semiquantitative analysis.
We would like to emphasize that information on aluminum hyperaccumulation can be gathered easily in unexplored families by simple but adequate methods, such as the aluminon test of leaves (Chenery, 1948a) or the chrome azurol-S test of wood (Kukachka & Miller, 1980).
1984), pyrocatechol violet (PCV) and aluminon (60 s) (Kerven et al.
The aluminon method is chosen because it alone, of the available methods, enables determination of the relatively high Al concentrations found in the soil solutions of some highly weathered, acid soils.
In each case the concentration of Al, measured by use of PCV and aluminon, is compared with the sum of the concentrations of free [Al.
Attempts to determine these usually involve the use of chromophores such as aluminon
and PCV (Kerven et al.
