“…In recent years, the method of solid phase extraction is used in sample preparation for analysis because of its high recovery, high enrichment factor, rapid phase separation, application of small volumes of organic solvents and low cost [2]. This method of samples pre-treatment is demanded even during the analysis of samples with such selective and highly sensitive methods as energy dispersive X-ray fluorescence and inductively coupled plasma [3][4][5][6][7][8]. The exclusion and regeneration of praseodymium from technological solution is also significant.…”

“…Various sorbents are used for praseodymium preconcentration via solid phase extraction technique, such as modified silica gel [3,4], carbon-ferrite magnetic nanocomposite [5], Muromac A-1 resin [6], Chromosorb 106-TAR resin [7], and Fe 3 O 4 @TiO 2 @P 2 O 4 nanoparticles [8]. Xiong et al [9] studied the adsorption of Pr(III) from aqueous solutions using strongly acidic cation exchange resin D72.…”

Sorptive properties of the Transcarpathian clinoptilolite towards Pr(III) were studied under dynamic conditions. The sorption capacity of clinoptilolite under optimal conditions (sorbent grain diameter of 0.20–0.31 mm; pH 9.0, temperature of preliminary precalcination of 350 °C, and flow rate of the Pr(III) salt solution with the concentration of 1.0 μg·mL−1 through the sorbent of 5 mL·min−1) was equal to 47.5 mg·g−1. The best desorbent of Pr from the clinoptilolite was the 1 M solution of KCl acidified with HCl to a pH value of 3.0. The method of Pr(III) trace amounts preconcentration in a solid phase extraction mode with further determination of this REE via spectrophotometric technique was developed. The linearity of the proposed method was evaluated in the range of 2–100 ng·mL−1 with detection limit of 0.7 ng·mL−1.

“…Type of eluent and pH were optimized in our off-line previous work. 37 Sample flow rate, eluent flow rate, breakthrough volume and interfering elements were studied and optimized in this survey. The optimum instrumental conditions for ICP OES were done by experimental design based on Box-Behnken model.…”

“…35,36 Our research group has previously reported an off-line methodology with octadecyl silica gel modified with quinalizarin prior to ICP OES determination of REEs. 37 In the present work, a simple on-line procedure for pre-concentration and determination of trace levels REEs and uranium (U) in natural water samples and carbonate mineral by ICP OES is proposed. The mini column is packed with cotton roll dyed by quinalizarin as sorbent material.…”

An on-line solid phase extraction (SPE) method using mini column packed with natural sorbent based on cotton roll dyed by quinalizarin was developed for simultaneously pre-concentration of rare earth elements and uranium at trace levels in environmental samples followed by inductively coupled plasma optical emission spectrometry (ICP OES) determination. Various parameters such as sample and eluent flow rate, sample volume and matrix ions on the method efficiency have been investigated. Under the optimized conditions, the limits of detection (LODs, 3σ) for rare earth elements were in the range of 0.002-0.300 µg L −1 and 0.420 µg L −1 for uranium. The relative standard deviation (n = 5) were lower than 6% except for samarium and uranium. The method was successfully applied for determination of trace rare earth elements and uranium in lake, well, tap water and carbonate mineral samples. The accuracy of the proposed method was validated by add-found method and direct analysis by ICP OES. This method has some advantages such as simplicity, rapidity, green chemistry and high sensitivity.

“…Одним із шляхів розв'язання цих аналітичних та технологічних проблем є метод твердофазової екстракції з використанням різноманітних сорбентів [2][3][4]. Для концентрування лантаноїдів, зокрема Yb(III), використовували модифіковані силікагелі [5,6], багатостінні вуглецеві нанотрубки [7], магнітні наночастинки [8], сорбенти на основі графену [9,10], хелатні й іонообмінні смоли [11,12], а також синтетичні цеоліти [13,14].…”

Вивчено сорбційні властивості Na-форми закарпатського клиноптилоліту стосовно слідових кількостей Yb(III) у динамічних умовах. Визначено оптимальні умови сорбції Yb(III) залежно від рН та концентрації розчину, термічної обробки сорбенту, впливу поширених іонів вод. Сорбційна ємність Na-форми клиноптилоліту щодо Yb(III) становить 8 100 мкг/г. Найкращим десорбентом Yb(III) є 1 М KCl, підкислений розчином HCl до рН 4,0, який забезпечує практично повне вилучення Ітербію. Розроблено методику концентрування слідових кількостей Yb(III) з водних розчинів у режимі твердофазової екстракції з наступним їх визначенням спектрофотометричним методом, який ґрунтується на взаємодії з арсеназо ІІІ.
