“…According to this model, an increase in the concentration of metal particles in the liquid phase leads to a higher concentration of ionic particles being adsorbed onto the surface of the solid substance (polymer) [ 64 ]. The model also suggests that the adsorption energy decreases exponentially as the adsorption centers of the adsorbent reach their maximum capacity [ 65 ]. This relationship can be described by the following linearized Equation (4):

where K f is the constant that relates to the sorption capacity of the adsorbent (the interpolymer system) for the species, and n is the constant that relates to the sorption intensity (the effect of lutetium concentration).…”

The growing demand for rare earth elements (REE) requires the search for economically viable materials to efficiently recover REE from various solutions. Our research aims to investigate the potential of using a combination of the ion exchangers Lewatit CNP LF (in H+ form) and AV-17-8 (in OH− form) as an interpolymer system, “Lewatit CNP LF@AV-17-8” (X:Y), with varying mass ratios of X:Y to enhance the sorption efficiency of lutetium ions from nitrate solution. During the study, we used a range of analytical methodologies, including gravimetry, ultraviolet-visible (UV-VIS) spectroscopy, and inductively coupled plasma optical emission spectroscopy (ICP-OES). Our findings demonstrate that the interpolymer system “Lewatit CNP LF@AV-17-8” (X:Y), with a mass ratio of 4:2, exhibited a significantly enhanced sorption rate of Lu3+ ions (42%) compared to the individual Lewatit CNP LF (6:0) (25%) and the individual AV-17-8 (0:6) (21%) over a 48 h period. Moreover, this interpolymer system has demonstrated notable conformity to the Freundlich adsorption model, highlighting its performance as an effective sorbent for lutetium (III) ions. Notably, our study presents a novel utilization of the interpolymer system “Lewatit CNP LF@AV-17-8” (4:2), with an adsorption capacity of 221.05 mg/g, to enhance the recovery of lutetium ions. The research findings demonstrate its potential for enhancing the recovery of REE.

An efficient sorbent for magnetic solid-phase extraction was developed from Fe 3 O 4 nanoparticles covered with aminated hypercrosslinked polystyrene. The sorbent has a saturation magnetization of 47 emu/g and a surface area of 509 mg/g and was tested for the extraction of 11 phenols from aqueous media. The optimum conditions were as follows: pH 3; adsorbent mass, 20.0 mg; adsorption time, 30 min; eluent (acetone) volume, 0.5 mL; and desorption time, 5 min. The enrichment factor after desorption reached 1595-1716 and the maximum adsorption capacity was 501-909 mg/g. Capillary electrophoresis was applied successively to separate 11 phenols after solid-phase extraction. The best separation was achieved using a fused silica capillary and borate buffer (pH 10.7) as a supporting electrolyte. After optimization, the linearity range was from 0.2 to 950 μg/L, and the limits of detection were 0.05-0.2 μg/L. The relative standard deviation varied from 6.1 to 8.7% (C = 1 μg/L) and from 2.9 to 3.5% (C = 500 μg/L). The determination of phenols is complicated in eutrophic water and spring water with a high content of humic and fulvic acids.
