Optimization and Evaluation of Polymer Inclusion Membranes Based on PVC Containing Copoly-EDVB 4% as a Carrier for the Removal of Phenol Solutions

Abstract

Polymer inclusion membrane (PIM) is a method for separating liquid membranes into thin, stable, and flexible film forms. In this study, the PIM was made using polyvinyl chloride (PVC), dibenzyl ether (DBE), and 4% copoly-eugenol divinyl benzene (co-EDVB) as a supporting polymer, plasticizer, and carrier compound, respectively. Furthermore, a phenol transport test was carried out using the parameters of pH influence, the effect of NaOH concentration, and transport time. The PIM membrane was also evaluated using the parameters affecting the concentration of plasticizer, the effect of salt concentration, and the lifetime of the PIM membrane. The results show that the optimum pH obtained to transport phenol to the receiving phase was 5.5, with a concentration of 0.1 M of the NaOH receiving phase and a transport time of 72 h. Furthermore, it was found that the use of plasticizers and salts affected the ability and resistance of the membranes. The membrane lifetime increased up to 60 days with the addition of 0.1 M NaNO3 or NaCl salt in the source phase.

Polymer Inclusion Membrane's 10% Copoly-EEGDMA-Containing Membrane's Lifetime and Optimization for Phenol Transport

“…50 mL of NaOH is used as the reception phase in one chamber tube, and 50 mL of 60 ppm phenol is used as the source phase in the other chamber tube. The 4-aminoantiphyrin technique was then used to determine the amount of phenol present in the source phase and receiving phase using a UV-Vis spectrophotometer with a maximum wavelength of 456 nm (Kiswandono et al 2022). The steps were as follows: The end volume was 10 mL after the addition of 5 mL each of the source phase, receiving phase, and standard phenol solution in a range of concentrations.…”

“…A plasticizer's load's impact PIM membranes were prepared with the use of plastizer with varied masses of 0.3032; 0.3100; 0.3132; 0.3200; 0.3232 g. Based on the procedures in the literature (Kiswandono et al, 2022), In this work, the amount of plasticizer employed was modified to create a membrane that is neither overly greasy nor rigid. The membrane was then moved between two tube chambers containing the source phase and the receiving phase after being weighed beforehand.…”

“…The same treatment was applied during the study at room temperature and was not exposed to sunlight in accordance with the chemical data sheet's recommendation that safe storage conditions are in a cool environment. Using a UV-Vis spectrophotometer and the 4-aminoantiphyrin technique, the concentration of phenol in both phases was determined (Kiswandono et al 2022).…”

“…According to the transport process's findings, phenol was delivered at a pH of 5.5 and had 34.07% of its total content in the receiving phase (% Cp). It was hypothesized that this transport is connected to hydrogen bonding since phenol and the carrier (10% co-EEGDMA) interacted negatively on the membrane surface (Kiswandono et al 2022).…”

Comparison of Kinetic Models Applied for Transport Description in Polymer Inclusion Membranes

“…This simple model, as represented by Equations (1) and (2), is most frequently used to describe transport kinetics in PIMs. For example, only last year, it was used to describe the removal of fluoride [ 8 ] and phenol [ 9 ], the separation of mercury(II) [ 10 ], the separation of lithium and magnesium [ 11 , 12 ], the recovery of bismuth(III) [ 13 ] and scandium [ 14 ], the extraction of arsenic(V) [ 15 ], the separation of Pb(II), Zn(II), and Cd(II) ions [ 16 ], and the removal of antibiotics [ 17 ].…”
