The absorption capacities (q) of the carbon monolith were
measured on various organic solvents and oils. In a typical
sorption test, certain carbon monolith (m0) was immersed
into various organic liquids (ethanol, coal oil, diesel oil, paraf-
fin oil, vegetable oil, peanut oil, castor oil) for 1 min, then took
out and weighed (mt) quickly. The absorption measurements
for all organic liquids were performed repeatedly five times.
The q value was calculated according to the following
equation:
q ¼ ðmt m0Þ=m0 100%
