Polymer Inclusion Membranes (PIMs) have been fabricated for diffusive passive sample layers. A study of various concentrations of plasticizers and characterization of PIM performance on phosphate transport has been carried out. The composition of PIM consisted of cellulose triacetate (CTA) as the base polymer, Aliquot 336-Cl as a carrier, and 2-Nitro phenyl octyl ether (2-NPOE) as a plasticizer. The plasticizer concentration varied between 0 and 10% (w/w). The performance of PIM on phosphate transport was studied with a passive sampler filled with 15 mL 0.1 M NaCl as the internal phase. The passive samplers were deployed into the bulk phase of a phosphate solution of 0.6 mg/L for 0-48 hours. The phosphate concentration in the passive sampler was determined using the visible spectrophotometry method at 691 nm (in the bulk phase) and 710 nm (in the internal phase). PIMs were characterized for stress-strain, contact angle, surface morphology, and cross-section. The sampling rate of phosphate, phosphate time-weighted concentration (CTWA), and accuracy of phosphate measurement was also determined. The results showed that PIM A (0% w/w 2-NPOE) resulted in a sampling rate of 0.0005±0.0002 (L/hour), CTWA 0.09 mg/L, and an accuracy of 28.38%. PIMs B (10% w/w 2-NPOE) resulted in a sampling rate of 0.0003±0.0001 (L/hour), CTWA 0.18 mg/L, and an accuracy of 52.15%. PIMs A and B have a contact angle of 17.02⁰ and 18.71⁰, respectively. It means that these PIMs are hydrophilic membranes. In addition, PIMs B was more elastic than PIMs A, showed by the tensile strength of PIMs B was 31.05 MPa compared with PIMs A's tensile strength (29.01 MPa). PIMs A and B have no pores, as shown by surface morphology using SEM. However, based on the cross-section area, PIMs A showed a break section instead of PIMs B, which indicates that PIMs B is more elastic than PIMs A.

“…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 ].…”

“…Noteworthy is the fact that, in some cases, the model fit quality is poor [ 15 , 17 ] or does not satisfy the criterion of a random distribution of residuals [ 10 , 16 ]. This means that a different or more advanced model should be used to describe the transport kinetics.…”

Five mathematical models for transport description in polymer inclusion membranes (PIMs) were presented and compared via regression analysis. The applicability of the models was estimated through the examination of experimental data of Zn(II), Cd(II), Pb(II), and Cu(II) ions transported by typical carriers. In four kinetic models, a change in the feed and stripping solution volume was taken into account. The goodness of fit was compared using the standard error of the regression, Akaike information criterion (AIC), Bayesian (Schwarz) information criterion (BIC), and Hannan–Quinn information criterion (HQC). The randomness distribution in the data was confirmed via a nonparametric runs test. Based on these quantities, appropriate models were selected.
