“…They are obtained from the two principal reactions, namely polycondensation and polymerization of monomers such as phenol and formaldehyde, styrene and divinylbenzene, acrylonitrile, acrylates and polyamines [12][13][14][15][16][17], leading to the cross-linked ion exchangers with a typical 4 to 20% cross-liking agent (mostly DVB) (Figure 1) [15].…”

Ion exchange technique as the reversible exchange of ions between the substrate and the surrounding medium can be an effective way of removing traces of ion impurities from the waters and wastewaters and obtaining a product of ultrapure quality. Therefore, it can be used in analytical chemistry, hydrometallurgy, purification and separation of metal ions, radioisotopes and organic compounds, and it also finds great application in water treatment and pollution control. In the presented paper, the new trends for ion exchanger characteristics determination and application are presented. Special attention is paid to the ion exchangers with multifunctionality for heavy metal ions removal. They show superior actions such as sorption capacity values with excellent resistance to fouling and the possibility of application in the co-current or modern packed bed counter-current systems, as well as for the condensate polishing or the conventional mixed bed systems in combination with other resins. The results of the paper are expected to help researchers to establish a powerful strategy to find a suitable ion exchanger for heavy metal ions removal from waters and wastewaters. It is important because the best ion exchangers are selected for a specific application during laboratory tests taking into account the composition of the feed solution, pH, type of ion exchangers and then the column breakthrough tests. Therefore, the optical profilometry and the X-ray photoelectron spectroscopy can prove beneficial for this purpose in the case of three different ion exchangers such as Dowex M 4195, Amberlite IRA 743 and Purolite Arsen Xnp.

“…Especially, ion-exchange resins may be superior for distillation, extraction, and crystallization in the case of separation and concentration of a specific ion in low concentration, which has attracted attention recently to a method of using anion-exchange resins for the removal, refinement, and recovery of organic ions (3)(4)(5). However, there has not been much 1 To whom correspondence should be addressed.…”
