“…The discharge of wastewater containing heavy metal ions, such as cadmium, zinc, mercury, chromium, lead, and so on, into surface water has exerted a negative influence on human health and environment. Their intracorporeal accumulation in a living tissue through a food chain can pose severe physiological or neurogenic damage . Among them, wastewater containing chromium is one of the major sources of environmental pollution.…”

A new polymeric adsorbent material based on polyethylene (PE) was prepared by photografting of 2‐(dimethylamino)ethyl methacrylate (DMAEMA) as a positively chargeable monomer to a PE film. The effects of the experimental parameters, such as the pH value, temperature, and grafted amount on adsorption of chromium(VI) (Cr(VI)) ions were investigated for the DMAEMA‐grafted PE (PE‐g‐PDAMEMA) films. The maximum adsorption capacity was obtained at the initial pH value of 3.0 for a PE‐g‐PDMAEMA film with 1.8 mmol/g and the maximum adsorption capacity obtained was higher than or compatible to those of many of the other polymeric adsorbents prepared for Cr(VI) ions. The adsorption kinetics obeyed the mechanism of the pseudo‐second order kinetic model and adsorption of Cr(VI) ions on PE‐g‐PDMAEMA films was well expressed by the Langmuir isotherm model. A high Langmuir adsorption constant suggests that the adsorption of Cr(VI) ions occurs between protonated dimethylamino groups and HCrO4− ions mainly through the electrostatic interaction. Cr(VI) ions adsorbed were successfully desorbed from a PE‐g‐PDMAEMA film in solutions of NaCl, NH4Cl, NH4Cl containing NaOH, and NaOH and a PE‐g‐PDMAEMA film was regenerated and repeatedly used for adsorption of Cr(VI) ions without appreciable loss in the adsorption capacity. © 2016 Wiley Periodicals, Inc.

“…Different types of adsorbents, such as activated carbon, sawdust, chitosan and modified chitosan, biomass materials, and synthetic polymers have been used for removal of Cr(VI) ions from aqueous medium. Unfortunately, some of these adsorbents do not have high adsorption capacities, and others have difficulty in regeneration or reuse.…”

In the present study, the synthesis of novel semi‐interpenetrating network (Semi‐IPN) hydrogel based on gum rosin alcohol‐psyllium (GrA‐Psy) has been reported. (Gum rosin alcohol‐psyllium)‐crosslinked‐poly(acrylic acid) [termed as (GrA‐Psy)‐cl‐poly (AA)] was synthesized using potassium persulphate (KPS) as an initiator and N, N′−methylene‐bis‐acrylamide (MBA) as crosslinker by free radical graft co‐polymerization technique. The prepared semi‐IPN was characterized using FTIR, XRD, and FE‐SEM. Further, the synthesized hydrogel was evaluated for the removal of malachite green (MG) dye from aqueous solution. Dye adsorption data was analyzed through various isotherm and kinetic models. Thermodynamic parameters and reusability of the synthesized adsorbent were also assessed. POLYM. ENG.

“…These parameters were used to study the feasibility and spontaneity of the adsorption process as well as the heat of the system. The parameters were obtained using the following equations at different temperatures

Δ G = - R T \ln K_{normalL}

\ln K_{L} = - \frac{Δ H}{R T} + \frac{Δ S}{R}

where T (K) is the reaction temperature, K L (L mol −1 ) is the Langmuir constant, and R (J/(mol · K)) is the gas constant.…”

A facile and economical strategy is designed to enhance the adsorption affinity of kaolin toward phosphate by acquiring calcium (Ca) and magnesium (Mg) from seawater. The modified kaolin is prepared at different temperatures to obtain CaO/MgO with different surface properties. The different modified kaolins are comparatively characterized using X‐ray diffraction, zero charge, BET surface area, energy dispersive spectrometry, and X‐ray fluorescence spectroscopy. Solution pH slightly affected the removal of phosphate by modified kaolin in the range of 4–7. The maximum adsorption capacity of the modified kaolin sintered at 600 °C (KS600) was 4.07 mg g−1, which is eleven times higher than that of raw kaolin. The presence of SO42− or CO32− ions demonstrates a negative effect on adsorption, whereas the presence of Cl−, F−, or NO3− exerted a negligible effect on removal efficiency. Importantly, KS600 had the capacity to remove phosphate effectively in real sewage. The strong interaction between phosphate and CaO/MgO played a key role in the enhancement of phosphate adsorption. These results indicate that the abundant ocean resources could be used for environmental remediation.
