“…Solid phase extraction also performs well in the preconcentration of trace metals with respect to minimizing solvent waste generation and the adsorption of analytes on the adsorbent in a more stable chemical form [21][22][23][24]. Adsorbents are preferred for the SPE of metal ions from environmental samples and these should have the following properties: the possibility for extracting a variety of metal ions over a wide pH range, high surface area, fast and quantitative adsorption and easy elution, ultra purity, repeated usability and accessibility [25][26][27][28][29]. Carbon nanotubes possess these properties and their use for enrichment and separation of metal ions at trace levels has been very popular in recent years [30][31][32][33][34].…”

Multiwalled carbon nanotubes were impregnated with 4-(2-thiazolylazo)resorcinol and used for the separation and preconcentration of Cd(II), Pb(II), Zn(II) and Ni(II) ions from food samples. The analytes were quantitatively recovered at pH 7.0 and eluted with 3 mol L −1 acetic acid. The effects of pH value, flow rate, eluent type and sample volume on the recoveries, and the effects of alkali, earth alkali and transition metals on the retention of the analytes were studied. The method was validated using the standard certified reference materials SRM 1570A (spinach leaves) and IAEA 336 (lichen), and the results were found to be compatible with the certified values of reference materials. The new enrichment procedure was applied to the determination of these ions in various food samples.

“…Among these REEs, lanthanum (La) is one of the commonly utilised metal for making super alloys, catalysts, special ceramics, condensers (Kütahyali et al 2010; Sert et al 2007). The major concern of REEs is the release of mineral acids, chelating agents and fission products emanating from expired nuclear fuel into the environment (Andres et al 2003).…”

In this study, the adsorption and desorption kinetics of lanthanum (La) on micro algal cells was investigated. The internal transcribed spacer (ITS) and 18S ribosomal RNA gene (rRNA) were used for molecular identification of the species. The algal species were found to have 95-98 % identities to Desmodesmus multivariabilis, Scenedesmus acuminutus, Chloroidium saccharophilum and Stichococcus bacillaris. The species were cultured and tested independently. Desmodesmus multivariabilis was found to be the most efficient at adsorbing lanthanum with a maximum sorption capacity (q max ) of 100 mg/g and a high affinity (b) of 4.55 L/g. Desorption of La was also highest in Desmodesmus multivariabilis with recovery up to 99.63% at initial concentration as high as 100 mg/L. Desorption data fitted best to the modified pseudo second-order with a better correlation coefficient (R 2 ) of ≤ 0.98 than first order model. The results showed feasibility of lanthanum recovery using algal sorbents, a cost effective method.

“…The biosorption capacities observed for Ce(III) and Eu(III) in the present study were superior to the results published in the literature. The leaf powders of Platanus orientalis exhibited 32.1 mg Ce(III)/g [21] and Pinus brutia exhibited 17.2 mg Ce(III)/g [42] compared to 144.9 mg Ce(III)/g by CSP in this study. In Eu(III) biosorption, Mycobacterium smegmatis exhibited 19.1 mg/g [43] and Pseudomonas aeruginosa showed 44.1 mg/g [44] and compared to 49.5 mg/g by CSP in this study.…”
