Molasses Decolorization of Activated Carbon

Molasses decolorization is a test directed towards activated carbon being used in sugar and glucose industries. And it covers predominantly the medium size pore range. In this test, a weighed amount of carbon is shaken in a water bath for 30 min with a molasses solution and filtered under strictly controlled conditions. Optical transmission is measured and compared to filtrates of a standard carbon treated in the same way. Both transmissions have to be matched within certain limits by changing the amount of activated carbon under test. The results are expressed as the number of milligrams giving the same decolorizing effect as the standard weight of standard carbon.
