Selective preconcentration of Lanthanum(III) byCoriolus versicolorimmobilised on Amberlite XAD-4 and its determination by ICP-OES

Preconcentration and determination of ultra-trace amounts of U(VI) and Th(IV) using titan yellow-impregnated Amberlite XAD-7 resin

“…In the last decades, a number of separation/preconcentration techniques have been utilised for the determination of trace amounts of toxic metal ions, including liquid-liquid extraction [10], precipitation [11] and solid-phase extraction (SPE) [12][13][14][15]. Among these techniques, SPE procedures are considered superior to other procedures due to their simplicity, flexibility, cost effectiveness, higher enrichment factors, ease of automation, low consumption of reagents and safety with respect to hazardous samples [16][17][18][19][20][21][22].…”

Biological substrates: Green alternatives in trace elemental preconcentration and speciation analysis

“…A moderate enrichment factor and sorption capacity was obtained (50 and 10.4 mg g −1 , respectively). Moreover, Coriolus versicolor has been immobilized on Amberlite XAD-4 and used as filling material of a column for La determination in natural water samples [93]. The column shows an acceptable stability and potential of regeneration, since it could be reused up to 60-fold.…”

Preparation, characterization and application of Saussurea tridactyla Sch-Bip as green adsorbents for preconcentration of rare earth elements in environmental water samples

“…Because of abundant functional groups (amino, carboxyl and hydroxyl) on the surface, the biomass materials can provide active sites for REEs. Various green biomass such as Bacillus subtilis [28], Pseudomonas aeruginosa [29], Coriolus versicolor immobilized on Amberlite XAD-4 [30], walnut shell [31], bacterial cells [32], Sargassum [33] and microorganisms [34] have been employed as SPE adsorbents for the adsorption of REEs. These biosorbents are economical, easily available, nontoxic and pollution free.…”
