A simple laboratory technique was used to determine sorption capacities of raw cotton fibers with hazardous liquids. For comparison purposes, other fibers such as kapok, milkweed, and polypropylene were also examined for their sorption capacities. The results showed that cotton fiber sorbed substantially higher amounts of liquid than both 15 and 3 denier polypropylene fibers but its sorption capacity was less than those of milkweed and kapok. It is concluded that raw cotton fibers are useful as sorbents in hazardous liquid cleanup application with certain advantages over synthetic sorbents such as polypropylene.
