الإجراء التجريبي

A total of 3.356 kg calcium carbonate (99.3%) is added in portions to 15.39 kg butrol (water contents: 2.6%) dissolved in 120 l demineralised water and it is stirred for one hour at 90° C. inner temperature. It is subsequently cooled to 20° C. and 1.5 kg active carbon (Norit SX PLUS; the carbon is first washed thoroughly with water) is added. It is stirred for one hour at 20° C. and the carbon is subsequently filtered off. The carbon is washed three times with 15 l of water each time.
