| Abstract | A new solid phase extraction method was developed for the preconcentration and determination of the rare earth elements (REEs) Pr, Sm, Eu, Gd, Tb, Dy, Ho, Tm, Yb, and Lu at trace levels using a mini-column packed with 8-hydroxy-2-quinolinecarboxaldehyde functionalized Amberlite XAD-4 resin. The REE ions were adsorbed onto the resin and then eluted with 2 mL of 1.0 mol L$^{−1}$ HNO$_{3}$ solution and determined using inductively coupled plasma-optical emission spectrometry (ICP-OES). In order to achieve the best performance for the method, the effects of several parameters such as sample pH, sample and eluent flow rate, sample volume, and matrix ions on the method efficiency were investigated. Under the optimum conditions, detection limits between 0.010 and 0.420 μg L$^{−1}$ for a preconcentration factor of 12.5 were achieved. The sorption capacities for the resin were found to range between 49.6 μmol g$^{−1}$ (for Yb) and 112.4 μmol g$^{−1}$ (for Pr). In order to verify the accuracy of the developed method, a certified reference material (SPS-SW2 Batch 127 surface water) was analyzed, and the results obtained were in good agreement with the certified values. The method was also successfully applied to the determination of REEs in water samples with recoveries in the range of 88.4–100.5 % being obtained. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
