Abstract
Technology for separation has improved significantly with the use of dynamic cavity
of non-cyclic ionophores in bulk liquid membranes to transport metal ions. Due to
their flexible and adaptive designs, these non-cyclic ionophores may selectively
form complexes with metal ions which make transport across liquid membranes more
efficient. Non-cyclic dynamic cavity of ionophores has special structural characteristics
that enable the creation of temporary cavities that are suited to hold particular
metal ions according to size and coordination chemistry. Target ions can be effectively
extracted and transported by means of selective binding which is facilitated by
concentration gradients or electrical potentials.
Examining these ionophores' selectivity, stability and transport kinetics, the study
highlights their benefits and applications. This technique has several uses such
as the purification of metals in metallurgy and mining, the elimination of hazardous
ions in environmental remediation and analytical uses in ion-selective electrodes.
This technology might lead to additional advancements in membrane and ion transport
technologies as well as improvements in industrial separation processes, environmental
protection initiatives and analytical procedures.
