“…As could be seen, increasing pH from 2 to 6 led to increasing adsorption efficiency of [23,24]. Besides, lead ions will be precipitated as hydroxide at pH values higher than 6.0 in the solution.…”

“…18,19 TiO 2 NPs have been tested as a sorbent in the solid-phase extraction for preconcentrated lead (Pb) in river water and seawater. [20][21][22] Zhang et al 20 investigated the potential acute toxicity of the interaction between TiO 2 NPs (50 nm and 120 nm) and lead acetate (PbAC) in mice. Suspensions of TiO 2 NPs (5 g/kg body weight) alone, PbAC (500 mg/kg) alone, and TiO 2 NPs (5 g/kg) plus PbAC (500 mg/kg) were administered to mice via oral gavage, respectively.…”

Due to their chemical stability and nonallergic, nonirritant, and ultraviolet protective properties, titanium dioxide (TiO 2 ) nanoparticles (NPs) have been widely used in industries such as electronics, optics, and material sciences, as well as architecture, medicine, and pharmacology. However, increasing concerns have been raised in regards to its ecotoxicity and toxicity on the aquatic environment as well as to humans. Although insights have been gained into the effects of TiO 2 NPs on susceptible biological systems, there is still much ground to be covered, particularly in respect of our knowledge of the effects of the interaction of TiO 2 NPs with other chemicals or physical factors. Studies suggest that interactions of TiO 2 NPs with other chemicals or physical factors may result in an increase in toxicity or adverse effects. This review highlights recent progress in the study of the interactive effects of TiO 2 NPs with other chemicals or physical factors.

“…Among them, SPE is extensively used due to its simplicity, high preconcentration factor, short extraction time, low consumption of organic solvents, and low cost [4]. Amberlite XAD resins, silica gel, activated carbon, nanomaterials, biological microorganisms, chelating polymers are the most widely employed adsorbents for SPE procedure [5][6][7][8][9][10][11].…”

Abstract:In this study, a novel method for the preconcentration of Al(III), Cu(II), Co(II), Pb(II), Mn(II), and Fe(III) in the form of their hematoxylin chelates using a column filled with Amberlite XAD-16 resin was proposed. Metal chelates collected on the resin were eluted and their determinations were carried out by flame atomic absorption spectrometry (FAAS). The influences of some analytical parameters including pH, flow rate, sample volume, and the type and concentration of eluent on the preconcentration efficiency were examined. The effects of some interfering ions on the recovery values of analytes were also investigated. While the optimum pH value was 8.5 for Cu(II), Co(II), Mn(II), and Fe(III) ions, it was 6.5 for Al(III) and Pb(II) ions. The appropriate eluent for quantitative elution was 8.0 mL of 1 mol/L nitric acid in acetone. Sample and eluent flow rates were found to be 2.0 mL/min. The maximum sample volume was established by changing it from 50 mL to 2500 mL. The sample volume does not significantly affect recovery within the range of 50-2000 mL of the sample volume for the investigated metal ions. The obtained preconcentration factor was 400. At optimum conditions, the detection limits found as concentration which is threefold of the standard deviation of the blank solution were 0.053 µg/L, 0.080 µg/L, 0.620 µg/L, 1.310 µg/L, 0.330 µg/L and 0.120 µg/L for Al(III), Cu(II), Co(II), Pb(II), Mn(II), and Fe(III) ions, respectively, and the adsorption capacities for these ions were 0.47 ± 0.02 mg/g, 0.81 ± 0.01 mg/g, 0.66 ± 0.01 mg/g, 0.58 ± 0.01 mg/g, 0.91 ± 0.01 mg/g, and 0.73 ± 0.02 mg/g, respectively. By using the certified reference materials, the accuracy of the method was verified. The proposed method was successfully applied to cigarette, hair, and some vegetable species.
