A chelating resin with bis[2-(2-benzothiazolylthioethyl)sulfoxide]: Synthesis, characterization and properties for the removal of trace heavy metal ion in water samples

Removal of Pb(II), Cd(II), Mn(II), and Zn(II) using iminodiacetate chelating resin by batch and fixed-bed column methods

“…The data presented in Table 1 reveals that, generally, the prepared chelating resin in this work has a good advantage in metal ion adsorption more than the previously reported resins. The capacity of the present chelating resin is 13.6, 8.4, 5.6, and 5 times more than Bis (2-2-benzothiazolylthioethyl sulfoxide) [39], SG-Cl-T-P [40], Salicylic acid type chelate adsorbent [36] and SG-Cl-T-P [40] with respect to Zn(II), Mn(II), Pb(II), and Cd(II), respectively. The adsorption isotherms provide information about the distribution of the adsorbate molecules between the liquid phase and solid phase, when the adsorption process reaches an equilibrium state.…”

Removal and recovery of Hg(II) from aqueous solution using chitosan-coated cotton fibers

“…Thiourea-nitric acid solution is usually applied in the desorption of Hg(II) from an adsorbent [32][33][34]. In the present study, a series of thiourea-nitric acid solutions of different concentrations were employed as eluents to desorb Hg(II) ions loaded on the SCCH and RCCH fibers.…”

Synthesis of porous acrylonitrile/methyl acrylate copolymer beads by suspended emulsion polymerization and their adsorption properties after amidoximation

“…Adsorption has become the efficient method because of its high efficiency, ease of handling, and availability of different adsorbents [4][5][6]. Thus, numerous adsorbents with various chelating groups for removing and recovering metal ions have been reported [7][8][9][10].…”
