“…Rapid and growing industrialization has led to excessive disposal of heavy metals. Now, environmental contamination with heavy metal ions is a serious problem owing to their strong toxicity for living beings, non‐biodegradability and tendency to accumulate in living organisms . Therefore, removal of toxic heavy metal ions from water bodies is considered one of the most important and challenging areas of water treatments.…”

Background Removing toxic heavy metal ions from water bodies is one of the most important areas of water treatment, and using porous membranes with a chelating function is a good route for this. Graft‐type porous membranes with a chelating function are innovate functional membranes. In this work, the main aims are to prepare such a functional membrane and evaluate its adsorption and rejection properties for heavy metal ions in water through adsorption isotherm experiments and permeation experiments. Results Glycidyl methacrylate (GMA) was graft‐polymerized on the surface of polysulfone (PSF) microfiltration membrane through a surface initiating system, getting the grafted membrane PSF‐g‐PGMA. Then the ring‐opening reaction of the epoxy group of the grafted PGMA was carried out with iminodiacetic acid (IDAA) as reagent, obtaining PSF‐g‐PGMA/IDAA membrane, on which a great deal of IDAA as chelating ligand was bonded. PSF‐g‐PGMA/IDAA membrane possesses a strong adsorption ability towards heavy metal ions via the chelating action and electrostatic interaction. The order of adsorption capacity was Pb2+>Cu2+>Cd2+, and the adsorption capacity of Pb2+ ion reached 4.5 µmol cm−2. When an injection filter with a membrane area of 1.77 cm2 was used, the rejection rate of PSF‐g‐PGMA/IDAA membrane for the three heavy metal ions with concentrations of 0.1 mmol L−1 were maintained at a level of 95% until the permeation solution volume reached 100 mL. Conclusion The grafted microfiltration membrane PSF‐g‐PGMA/IDAA can be easily prepared and possesses excellent rejection and removing performance towards heavy metal ions © 2018 Society of Chemical Industry

“…Water contamination by heavy metals is a grave environmental issue, and the most of heavy metal pollutant source is industrial wastewater. Heavy metal ions in water have become a severe threat to human health and the environment because of their severe toxicity and a tendency to accumulate in living organisms . Among heavy metal ions, Pb(II) is considered to be highly toxic to human and living beings.…”

3‐Hydroxy‐N,N‐diethylaniline (HDEA) as a tertiary aromatic amine was introduced onto the surface of chloromethylated polysulfone (CMPSF) microfiltration membrane through modification reaction, resulting in the modified membrane PSF‐DEA. A redox surface‐initiating system (DEA/APS) was constituted by the bonded tertiary aromatic amine group DEA and ammonium persulfate (APS) in aqueous solution, and so, the free radicals formed on the membrane initiated sodium p‐styrenesulfonate (SSS) as an anionic monomer to produce graft polymerization, getting the grafting‐type composite microfiltration membrane, PSF‐g‐PSSS membrane. Subsequently, the adsorption property of PSF‐g‐PSSS membrane for three heavy metal ions, Pb2+, Zn2+, and Hg2+ ions, was fully examined, and the rejection performance of PSF‐g‐PSSS membrane towards the three heavy metal ions was emphatically evaluated via permeation experiments. The experimental results show that by the initiating of the surface‐initiating system of DEA/APS, the graft polymerization can smoothly be carried out under mild conditions. PSF‐g‐PSSS membrane as a functional microfiltration membrane has strong adsorption ability for heavy metal ions by right of strong electrostatic interaction (or ion exchange action) between the anionic sulfonate ions on the membrane and heavy metal ions. The order of adsorption capacity is Pb2+ > Zn2+ > Hg2+, and the adsorption capacity of Pb2+ ion gets up to 2.18 μmol/cm2. As the volume of permeation solutions, in which the concentrations of the three metal ions are 0.2 mmol/L, are in a range of 50 to 70 mL, the rejection rate of PSF‐g‐PSSS membrane for the three heavy metal ions can reach a level of 95%, displaying a fine rejection and removing performance towards heavy metal ions.

“…Many naturally occurring adsorbents have been successfully used for the removal of metal cations from aqueous media, including clays 3 , plant biomass 4 and material enriched with humified organic matter 5,6 . Humified organic matter is formed by the chemical and microbiological decomposition of different organic precursors, such as proteins, carbohydrates and lipids.…”

Samples of vermicompost were used to decontaminate aqueous media containing Cd2+, Cu2+, Mn2+, Ni2+, Pb2+ and/or Zn2+ at concentration up to 10X higher than the limits of National Council of the Environment (Resolution 430/2011). For this purpose, 50.00 mL of synthetic solutions and wastewater from a chemical laboratory were stirred with dried vermicompost (~10.0000 g), in natura or with diameter ≤ 0.053 mm. Aqueous media were treated with vermicompost, either at rest (24, 48, 72, and/or 96 h) or under mechanical agitation (2, 4, 6, 8, and/or 10 h). All elements were spectrometrically determined in the different supernatants. In the synthetic solutions, except for Mn2+and Zn2+, all cations were undetectable (concentrations lower than the legal limits), when in natura vermicompost was used. After treating synthetic solutions with sieved vermicompost, Cd2+, Cu2+, Ni2+, Pb2+ e Zn2+ concentrations were undetectable, while Mn2+ concentrations were too close to the legal limits. In the wastewater, Cd2+and Pb2+ concentrations, which were 1.5 and 3.8X higher than the legal limits, respectively, were undetectable after treatment with vermicompost in natura. Besides its efficiency of retaining the evaluated metallic cations, vermicompost was able to increase the aqueous media pH from 0.9 to 6.0 ± 0.5.
