Molasses number of activated carbon
About
The Molasses number (DSTM 16) is a measure of the decolorizing capacity and is an indicator of the macro pore and transport pore structure of activated carbon. An amount of pulverised carbon is mixed and heated with a standard molasses solution for a period of time. The Molasses number is expressed as the relative amount of colour removed by an activated carbon compared to a standard carbon. So the higher the molasses number, the better the product.
Molasses number
Normally, it is impossible to compare molasses numbers of different suppliers as the value depends on several factors:
- Molasses standard solution;
- pH of the test;
- Buffered or unbuffered molasses solution;
- Standard carbon;
- Type of test.
Molasses tests methods
Some molasses test methods are expressed as the amount of carbon required to obtain a certain decolorization of a standard molasses solution. Activated carbons with a lower molasses number then have a better decolorizing capacity in this type of test methods.
