“…The preconcentration factor and detection limits of the proposed method are comparable with various separationpreconcentration methods. [13][14][15][28][29][30][31][32][33][34] The low RSD of real sample analysis is an indication of methods versatility for real sample. …”

“…The small volume of the surfactant-rich phase obtained with this methodology permits the design of extraction schemes that are simple, cheap, highly efficient, and of lower toxicity to the environment than those extractions that use organic solvents. The CPE phenomenon has been used for the extraction and preconcentration of metal cations [13][14][15][16][17][18][19] after the formation of sparingly water-soluble complexes. CPE has been shown to be an effective sample preconcentration technique for improving sensitivity and selectivity prior to atomic spectrometry.…”

“…[4][5][6][7][8][9][10] Sodium dodecylsulfate (SDS), which has low toxicity and is easily biodegraded, was used as the extraction medium. The purpose of this study is the extraction of a copper(II) ammine-complex with SDS after ion-pair formation.…”

“…To date, CPE has been used for the extraction and preconcentration of metal ions after the formation of sparingly water-soluble complexes; then the complex in the surfactant-rich phase is determined by different spectrometric methods. [22][23][24][25][26][27][28][29][30][31] In the present work, we report on the results obtained from applying the CPE for the extraction of Ag + and Mg 2+ ions from various samples and their determination by flame atomic absorption spectrometry.…”
