Abstract
Adsorpsi elemen logam pada resin chelating fase padat mungkin merupakan metode pemisahan dan prekonsentrasi yang paling efektif. Dalam pekerjaan ini, ekstraksi fase padat portabel (SPE) dibangun menggunakan jarum suntik plastik yang tersedia secara komersial yang berisi sejumlah resin chelating analiq ME-02. Kemampuan SPE portabel ini dievaluasi melalui proses adsorpsi-desorpsi tembaga, timbal, dan kadmium sebelum penentuan mereka dengan spektrometri penyerapan atom (AAS). Beberapa parameter yang memengaruhi desorpsi adsorpsi ion logam berat ini pada analiq ME-02, yang meliputi efek pH dan konsentrasi eluent ((HNO3), diselidiki secara rinci. Ditemukan adsorpsi kuantitatif (90%) dari tembaga (90%) , timbal, dan kadmium diperoleh pada semua pHS (4-8) diperiksa, sedangkan 1 m HNO3 ditemukan efektif untuk desorpsi logam-logam ini dengan pemulihan pada kisaran 93 -114%. Hasil tersebut menunjukkan bahwa analig itu -02 Memiliki kemampuan chelating yang sangat baik (pH-independen) untuk adsorpsi tembaga, timah, dan kadmium, sedangkan sistem SPE portabel menyediakan kemudahan dan efektivitas untuk pengumpulan / prekonsentasi elemen logam.
English Abstract
The adsorption of metallic elements on the solid phase chelating resins is probably the most effective separation and preconcentration methods. In this work, portable Solid phase extraction (SPE) was constructed using a commercially available plastic syringe containing certain amount of the Analiq ME-02 chelating resin. The ability of this portable SPE was evaluated through adsorption-desorption process of copper, lead, and cadmium prior their determination by atomic absorption spectrometry (AAS). Some parameters affecting the adsorption-desorption of these heavy metal ions on the Analiq ME-02, which include effect of pH and concentration of eluent ((HNO3), were investigated in detail. It was found that quantitative adsorptions (90%) of copper, lead, and cadmium are obtained at all pHs (4-8) examined, whereas 1 M HNO3 was found to be effective for the desorption of these metals with the recoveries in the range of 93 -114%. Such results indicated that Analig ME-02 has excellent chelating ability (pH-independent) for the adsorption of copper, lead, and cadmium, while portable SPE system provides easiness and effectiveness for collection/preconcentation of metallic elements.
