Abstract

Phenols are widely produced and used for industrial purposes. As a result, many phenol wastes are found that are wasted in the environment, especially the aquatic environment. Because of the nature of phenols that can harm living things, the process of separating phenols from waters was performed by the Polymer Inclusion Membrane (PIM) method. The PIM membrane was prepared with a composition of carrier compound copoly (eugenol-DVB) 4% which has been synthesized, polyvinyl chloride (PVC) as supporting compounds, and diethyl benzene (DBE) as plasticizers. The result of the synthesis of copoli-EDVB 4% produced a slightly orange colored powder with a yield of 92%, melting point in the range of 98-101 °C and soluble in organic solvents such as chloroform, tetrahydrofuran, and diethyl ether. The result of IR spectroscopy on copoly-EDVB 4% powder showed the occurrence of cross links between eugenol and divinyl benzene (DVB) shown by the presence a wave number at around 3511.2 cm-1 as indication of -OH group from eugenol. The TG-DTA analysis was also carried out on Co-EDVB 4% crosslinked powder to monitor the changes in sample weights towards reference. The phenol transport test on PIM membrane with co-EDVB 4% as a carrier compound with membrane reusability analysis, with five repetitions has also been done to test the stability and durability of the membrane. The IR spectroscopy was done to characterize the PIM membranes before and after phenol transport in the repeated use and artificial waste tests. The phenol content transported from the source phase to the receiving phase was analyzed by UV-Vis spectroscopy.
