Abstract:The effects of adsorbent type (10 types of adsorbents), adsorbent dosage, adsorption temperature and adsorption time on the removal of 5 plasticizers in camellia oil were investigated. The results showed that the optimal adsorbent was H-2 activated carbon, followed by 55F-A activated carbon, 55JN-C activated carbon, attapulgite and activated clay, when the adsorption temperature was 110 ℃, the adsorption time was 30 min and the dosage of adsorbent was 2.0%. Under the optimal condition (the adsorption temperature was 130 ℃, the adsorption time was 50 min and the dosage of the H-2 activated carbon was 2.0%), the removal rates of DMP, DEP, DIBP, DBP and DEHP were 76.7%, 50.7%, 52.4%, 22.2% and 6.1%, respectively. Removing DMP, DEP and DIBP from camellia oil by adsorption was efficient, while inefficient for high molecular weight DBP and DEHP.
