Cat.No. 100594 Spectroquant® Aluminium Cell Test
Cat.No. 114825 Spectroquant® Aluminium Test
Cat.No. 100317 Hydrochloric acid 37 % for analysis
Cat.No. 109137 Sodium hydroxide solution 1 mol/l
Cat.No. 109535 Universal Indicator strips pH 0 - 14
Cat.No. 116754 Water for analysis


In a glass beaker place 25 ml of the sample with 5 ml of hydrochloric acid 37% and 2.5 ml of nitric acid 65%, mix, and boil for 1 hour. Cover the beaker with a clock - glass during the operation. Dissolve the residue in water for analysis and transfer to a 25-ml volumetric flask. Before filling up with water for analysis, check the pH by using Universal Indicator strips pH 0 - 14. The optimum pH range is 3 - 10, if necessary, adjust with sodium hydroxide 1 mol/l. Then fill up to the mark and mix well.


Determine with the above mentioned test kits.


Aluminium (total) content in mg/l Al = analysis value in mg/l Al
