Warm with a solution of ammonium acetate, and filter.

Either hydrolysis or ammonolysis reactions of the initial electrochemical oxidation products can occur with pH 7 ammonium acetate buffer.

In the soil, the content of As extracted with acqua regia and that extracted with ammonium acetate, were analyzed.

The column was then washed with a 3 ml of 0.1 M ammonium acetate buffer (pH 6).

The precipitation of lead from acid solutions with sulphuric acid, and the solubility of the precipitate in ammonium acetate, distinguishes it from all other metals.
