“…Zirconium-based metal-organic frameworks (Zr-MOFs) have become the focus of research in analytical chemistry due to their promising properties, including good selectivity, high performance, low cost, and regeneration, as well as the strong interaction of framework metal centers with functional groups of organic pollutants [1][2][3][4][5][6][7]. The strong bonds between the metal and carboxyl groups are responsible for the high stability of Zr-MOF [1,[8][9][10].…”

Currently, among the various areas of targeted wastewater treatment, great attention is being given by researchers to the solid-phase extraction of organic dyes using metal–organic frameworks (MOFs). In this work, a mixed-ligand Zr-MOF containing terephthalic acid and 1,10-phenanthroline as linkers was used for this purpose. The limiting adsorption of the dyes Congo red and methylene blue, according to experimental data, is 40 mg/g. The influence of various parameters (time, temperature, adsorbent dosage, pH, and coexisting ions) on adsorption characteristics was studied. The sorbent was tested for the removal of dyes from drinks in water and in artificial seawater. The possibility of the separation of dyes by column chromatography using a sorbent as a filler was studied.

“…Zirconium-based metal-organic frameworks (Zr-MOF) have quickly gained a lot of attention in analytical chemistry due to their promising properties, including good selectivity, high productivity, low cost and regenerability, and strong interaction of Zr-OH groups with specific functionality of pollutants (Cavka et al 2008;Butova et al 2016;Tsivadze et al 2019;Solovtsova et al 2020;Pribylov et al 2021;Uflyand et al 2021;Bai et al 2016). This is explained by high chemical and mechanical stability of Zr-MOFs due to the formation of strong bonds of zirconium with carboxyl groups (Cavka et al 2008;Wu et al 2013;Howarth et al 2016;Schaate et al 2011).…”

Effective removal of organic dyes from aqueous solution is an important task for targeted wastewater treatment. In this work, a mixed-ligand Zr(IV) metal organic framework based on terephthalic acid and 1,10-phenanthroline was used for the solid-phase extraction of dyes. The maximum adsorption capacity of the sorbent for Congo red and methylene blue dyes reached 40 mg/g. The adsorption behavior was studied, including the effect of time, temperature, adsorbent dosage, pH and coexisting ions. The reliability of the sorbent for removing artificial dyes from food samples and in artificial seawater was tested. The possibility of using the sorbent as a filler for column chromatography for dye separation is shown.
