“…The situation is the same for PPLM. From this, dibenzo-21-crown-7 (DB21C7) [ 42 , 43 ] was adopted as a transporter instead of DB18C6, membrane transport of Cs + was studied since the isotope 135 Cs, which is formed in nuclear reactors, has a long half-life of 2.3 × 10 6 years, 137 Cs 30.17 years, 134 Cs 2 years, and so forth [ 44 , 45 ].…”

A polymeric pseudo-liquid membrane (PPLM) was constructed from poly(N-oleylacrylamide) (PC18AAm), which exhibited a rubbery state under membrane transport conditions and used as the membrane matrix. In the present study, dibenzo-18-crown-6 (DB18C6) and dibenzo-21-crown-7 (DB21C7) were adopted as transporters for alkali metal ions. KCl was adopted as a model substrate for DB18C6 and CsCl the latter. Chiral transporter, O-allyl-N-(9-anthracenylmethyl)cinchonidinium bromide (AAMC) was used as a transporter for chiral separation of a racemic mixture of phenylglycine (Phegly). The l-somer was transported in preference to the antipode. The present study revealed that PPLMs are applicable to membrane transport, such as metal ion transport and chiral separation.
