Research on oil
absorption test has revealed that lipophilic polyelectrolyte resin
had higher oil absorbency, faster oil-adsorbing rate, and
better reusability compared with non-ionic oil absorption resin.
Meanwhile, the effect of the content of ionic groups on the
oil absorbency of the lipophilic polyelectrolyte resin was also
investigated. The results showed that the maximum of oil
absorbency of the resin to the carbon tetrachloride was
37.86 g/g when the content of ionic groups was 4.54 wt%.
