Dehydroacetic acid as a reagent for the separation and gravimetric determination of copper(II), aluminium and beryllium.

Dehydroacetic acid is proposed as a reagent for the gravimetric determination of copper(II), aluminium and beryllium at pH 3.0-6.0, 3.0-6.0 and 7.5-9.5 respectively. Copper is weighed as the complex Cu(C(8)H(7)O(4))(2). Aluminium and beryllium are weighed as Al(2)O(8) and BeO. The reagent is easy to prepare.
