Sample Preparation:

In a nickel crucible mix about 100 mg of powdered sample material with 8 pellets of sodium hydroxide (1.5 g). Heat the covered crucible with a gas burner for 30 min to weak redness. After cooling dissolve the content of the crucible in water. For this purpose put the crucible with the cover into a beaker and heat with 30 - 50 ml water for analysis on the water bath, until the molten mass has dissolved. Ultra sonification accelerates the dissolution. Adjust the solution with hydrochloric acid 37% to a pH - the value of 3 - 4, transfer quantitatively into a 200-ml volumetric flask, fill up to volume with water for analysis and mix well.


Determine with the above-mentioned test kits.
