The removal of phosphate from water has attracted increasing attention because the dominant role in eutrophication. In this study, a novel nanoscale hybridized adsorbent, NLC@213, was fabricated by immobilizing nanosized lanthanum carbonate (NLC) into pores macro-porous polyacrylic anion exchanger D213 through an in-situ precipitation method for adsorption wastewater. NLC@213 exhibited excellent pH tolerance and possessed high selectivity presence competing anions (Cl–, NO3–, SO42–, SiO32–,...

Adsorption using anion exchange resins is an efficient method for the removal of aromatic sulfonic acids (ASAs) from industrial wastewater. In this study, a series weak-base exchangers (SD1–SD5) were synthesized to investigate effect functional group density on adsorption ASAs wastewater containing competitive inorganic anions. p-Toluene acid (PTSA) was selected as target pollutant, and Na2SO4 chosen salt because its widespread existence in performances these evaluated compared terms...

A novel anion exchange resin AEE-3 was synthesized by N-alkylation of a weakly basic polyacrylic exchanger D311 with 1-bromopropane to effectively remove nitrate (NO3−-N) from aqueous solution. The related finding revealed that its adsorption isotherm obeyed the Langmuir model well, and second-order more validated for NO3−-N kinetics study. Compared commercially-available polystyrene-based specialty Purolite 520E (A520E), has higher adsorbed amount better regeneration performance toward in...

In this study, a novel asymmetric amine-based strongly basic anion exchange resin SE-1 was synthesized successfully via the reaction of chloromethylated styrene–divinylbenzene copolymer with N, N-dimethyloctylamine. The sorption performance for selective removal nitrate in aqueous solution compared to commercially available specialty resin, namely Purolite A 520E (A 520E). It found that kinetic data could be described better by pseudo-second-order model, and indicated faster kinetics than...

Abstract Aromatic sulfonic acids (ASAs) play a pivotal role as essential intermediates in numerous industrial manufacturing, while large amount wastewater with various ASAs and high concentration of inorganic salts is subsequently generated. The effective separation removal from challenging due to their complex chemical composition the limited selectivity common adsorbents. Herein, novel surface imprinted polymer (H‐SIP) excellent salt resistance was designed PEI/Cl‐PS‐DVB carrier...

Polydopamine-modified granule organo-attapulgite adsorbent (PDA-GOAT) was facilely prepared via a dip-coating approach. The samples were characterized by scanning electron microscopy, X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. Surface area pore size calculated from the Brunauer-Emmett-Teller method N2 adsorption-desorption isotherm. adsorption behaviour of methylene blue (MB) onto PDA-GOAT systematically investigated. experimental data revealed that process...

In the current work, poly(4-vinylpyridine) (P4VP) was grafted on a macroporous polystyrene resin via free-radical polymerization by using pendent vinyl group. The grafting conditions such as swelling agent, initiator concentration, reaction temperature, and amount of 4-vinylpyridine (4VP) monomer were optimized, three resins with different 4VP amounts (SC-1, SC-2, SC-3) chosen adsorbents. P4VP-grafted characterized scanning electron microscopy, N2 sorption/desorption isotherms, Fourier...

A novel composite adsorbent was prepared by polydopamine (PDA) coating, amination, and carboxylation modification using basalt fiber (BF) as the carrier material for removal of Cu2+ from water. The resulting adsorbent, BF/PDA-iminodiacetic acid (IDA), characterized scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy thermogravimetric analysis. effects pH, ionic strength, temperature, duration on adsorption properties BF/PDA-IDA were...

Two novel weakly basic anion exchange resins BNH and BN2 bearing two different functional groups was fabricated via the two-step amination of chloromethylated polystyrene-divinylbenzene beads with dibutylamine dimethylamine. The adsorption properties for 2-naphthalenesulfonic acid (NSA) removal from wastewater were compared synthesized monofunctional BN0 BN6 (derived dimethylamine dibutylamine, respectively). experimental data revealed that process on four fitted well pseudo-second-order...

As potential persistent and toxic organic contaminants, organophosphorus pesticides (OPPs) are frequently detected in various waters. However, few studies available on removing OPPs aqueous solution through heterogeneous catalytic activated peroxymonosulfate (PMS). Herein, Zr-doped Fe3O4 magnetic nanoparticles were prepared via a facile solvothermal method employed to activate PMS for degrading diazinon. A series of characterization performance tests revealed that Zr(0.3)Fe3O4 composite...
