To cite this article: Z.A. Alothman, Y.E. Unsal, M. Habila, M. Tuzen & M. Soylak (2015) A membrane filtration procedure for the enrichment, separation, and flame atomic absorption spectrometric determinations of some metals in water, hair, urine, and fish samples, Desalination and Water Treatment, 53:13, 3457-3465, A cellulose acetate membrane filter was applied for solid-phase extraction of Cd(II), Co(II), Cu(II), Fe(III), Ni(II), and Pb(II) from urine, hair, fish, and various water samples. The analyte ions were adsorbed on membrane filter as Cochenille red complexes and then eluted using 10 mL 3 M CH 3 COOH. The matrix effects from concomitants and analytical parameters, including pH, sample volume, membrane type, and flow rates, were investigated. The analyte ion detection limit for the proposed method was in the range 1.0-5.2 μg/L. The preconcentration factors were calculated as 30 for Cu(II), 40 for Co(II), Ni(II), Cd(II) as well as Pb(II), and 50 for Fe(III). The proposed method was validated by analyzing certified reference materials. This method was successfully applied to water, hair, fish, and urine samples with good results.

Combination of Syringe–Solid Phase Extraction with Inductively Coupled Plasma Mass Spectrometry for Efficient Heavy Metals Detection

“…The desorption process depends on the tendency of the adsorbed metal ions to dissolve and completely transfer to the aqueous phase. Usually, acid solutions are used for this purpose . In the present study, different acid solutions were tested for the recovery of the adsorbed Pb(II), Cd(II), and Zn(II) from NH 2 ‐HCMSSs; these included HNO 3 , HCl and acetic acid, with concentrations ranging from 1 to 3 M. The percent recoveries shown in Fig.…”

“…At a sample volume of 120 mL, the recovery began to decrease for Pb(II), Cd(II), and Zn(II). The preconcentration factors were calculated as 33.3 for Pb(II), Cd(II), and Zn(II), considering that the eluent volume used was 3 mL .…”

“…Various adsorbents have been reported for use in SPE, such as Amberlite XAD resins , cellulose acetate membranes , 4‐(2‐thiazolylazo) resorcinol‐modified activated carbon , modified silica gel , multiwalled carbon nanotubes impregnated with 4‐(2‐thiazolylazo) resorcinol and alumina .…”

A new coprecipitation method without carrier element for separation and preconcentration of some metal ions at trace levels in water and food samples

“…To overcome these limitations, several technologies have been widely used to pre-concentrate and separate trace metals, such as liquid-liquid extraction [5,6], cloud point extraction [7,8], solid phase extraction [9][10][11][12][13], membrane filtration [14,15] and electroanalytical [16,17] techniques.…”

Functionalization of polyacrylonitrile nanofiber mat via surface-initiated atom transfer radical polymerization for copper ions removal from aqueous solution

“…Several technologies have been developed for the removal of Cu 2+ from aqueous solution, such as electrodeposition [3,4], ion exchange [5,6], membrane separation [7][8][9][10][11], adsorption [12][13][14][15][16], etc. Compared to other methods, adsorption is simple and effective due to its easiness to operate and simplicity to design.…”
