“…The received values of molar flux J and the permeability coefficients P are comparable with the values received by other authors for transport of organic compounds(10) or metal ions (14,25) through PIM. It can be seen that in the case of membranes with the TBP as a plasticizer, those values are high.…”

“…These membranes owe their origin to ion-selective electrode (ISE). Therefore, the majority of publications concerning the PIM is connected with the transport of metal ions such as zinc (12)(13)(14), chromium(VI) (15,16), copper (17,18), gold (19), lead (14,20,21), and many others (22)(23)(24)(25). In these publications it was shown that these membranes are suitable for releasing of various types of metal cations, preserving the high degree of selectivity.…”

Research, about citric acid transport, through the polymer inclusion membranes, have been carried out. Two different plasticizers -ONPOE and TBP and a series of carriers of tri-octylamine and 1-alkylimidazoles with carbons chain length of 10, 11, 12, 14, and 16 atoms were used. It was found out that for 1-alkylimidazoles values of the permeability coefficients obtained for TBP as plasticizer change in the range of 8.81 Ã 10 À7 m/s to 1.92 Ã 10 À6 m/s. When ONPOE was used as the plasticizer, the values change in the range of 1.43 Ã 10 À9 m/s to 2.24 Ã 10 À8 m/s. The value of the permeability coefficient for the membrane with TBP equals 3.49 Ã 10 À7 m/s and is comparable with the value obtained for the TOA with this plasticizer, which equals 4.77 Ã 10 À7 m/s TBP, therefore, it is able to simultaneously act as a plasticizer and carrier in membrane. Tested membranes are characterized by a high durability. The repeated 5-times, 24-hours cycles of research did not show any decrease in transport capacity of citric acid.

“…This finding indicates that it would be possible to make a kinetic separation of Ni 2+ with respect to Co 2+ and Cu 2+ in a multicomponent ion solution if a low agitation time is used. For example, the separation of Co 2+ , Cu 2+ , and Ni 2+ from aqueous solutions is often required in hydrometallurgy processing (Pośpiech and Walkowiak, 2007) and industrial wastes (Yavuz et al, 2003).…”

a b s t r a c tA new carboxylated-functionalized sugarcane bagasse (STA) was prepared through the esterification of sugarcane bagasse with trimellitic anhydride. The optimized synthesis conditions yield STA with a percent weight gain of 73.9% and the number of carboxylic acid groups accounted for 3.78 mmol/g. STA was characterized by FTIR, elemental analysis, TGA, PZC, and SEM. Adsorption kinetics followed a pseudosecond-order model. The adsorption rate constant showed the following order: k 2,Ni 2+ > k 2,Cu 2+ > k 2,Co 2+ . Four mono-and multi-component isotherm models were used to model the adsorption systems. Monocomponent experimental data were fitted to Langmuir and Sips models; whereas, multicomponent data were fitted to modified extended Langmuir and P-factor models. The maximum adsorption capacities (Q max,mono ) obtained from the Langmuir model were 1.140, 1.197, and 1.563 mmol/g for Co 2+ , Cu 2+ , and Ni 2+ , respectively. The competitive studies demonstrated that the multicomponent adsorption capacity (Q max,multi ) was smaller than Q max,mono , as a result of the interaction between the metal ions. Desorption studies showed that all metal ions could be fully desorbed from STA.

“…However, the main disadvantage of this method is the use of large volumes of organic solvents and the active compounds, which are often toxic for microorganisms applied in the fermentation processes (15,16). Another possibility which has been recently developed is a method using polymer inclusion membranes (17)(18)(19)(20)(21)(22). Such a solution can allow not only for the reduction of the quantity of harmful by-products, but also reduce the amount of the substance used as carriers in the PIM.…”

As part of this work the study of transport of organic acids, namely oxalic, tartaric, and lactic acids through polymer inclusion membrane were carried out. As a polymer matrix cellulose triacetate (CTA) and as a carrier 1-alkiloimidazole (IMI-n, n = 10, 11, 12, 14) were used. The aim of this study was to determine the effect of the qualitative and quantitative composition of the polymer inclusion membrane on the transport rate of selected organic acids. On the basis of the obtained results and percolation theory, a theoretical description of the phenomenon of separation processes was proposed. Also, the percolation threshold for the separated organic acids was determined.
