“…Han et al [27] have developed an adhesive and transferable free-standing film with dual function of osteoinductivity and antibacterial activity, which is obtained by sequentially assembling vancomycin immobilized oxidized sodium alginate and dexamethasone encapsulated chitosan-coated BSA nanoparticles on a poly-dopamine layer. Our previous reports also have demonstrated that surface modification of different materials via mussel-inspired chemistry and Michael addition reaction [28][29][30][31][32][33][34][35][36][37][38][39][40][41].…”

Adsorption is an effective and commonly adopted method for removal of organic pollutants from environment. In this work, we described the synthesis and the adsorption behavior of poly(sodium p-styrenesulfonate hydrate) (PSPSH)-modified kaolin, which was obtained by combination of mussel-inspired chemistry and Michael addition reaction. The amino-terminated PSPSH was synthesized by free radical polymerization using cysteamine hydrochloride as the chain transfer agent and sodium p-styrenesulfonate hydrate as the monomer. Raw kaolin and PSPSH-modified kaolin were characterized using several techniques including transmission electron microscopy, Fourier transform infrared spectroscopy, thermal gravimetric analysis, and X-ray photoelectron spectroscopy in detail. The adsorption of methylene blue onto modified kaolin from aqueous solution was investigated, in which the effects of contact time, temperature, solution pH, and initial methylene blue concentration were studied. The experiment data were analyzed using two common adsorption models: Langmuir and Freundlich isotherm models. The kinetic adsorption data were analyzed using pseudo-first-order, pseudo-second-order, and intraparticle diffusion model. The values of thermodynamics constants such as entropy change (DS 0 ), enthalpy change (DH 0 ) and Gibbs free energy (DG 0 ) were also determined. The modified kaolin showed favorable dispersibility and convenient separation, high efficiency, and good regeneration capability in the removal of methylene blue from solution.Qiang Huang and Meiying Liu have contributed equally to this work.

“…The results showed a quite high recovery percentage of Cd(II) and Pb(II). Zhou et al [75] used MWCNTs as the adsorbent and sodium diethyldithiocarbamate as the chelating agent for the simultaneous enrichment of Ni(II), Co(II), and Hg(II) in river water, sewage water, and factory water, respectively, and satisfied results were achieved.…”

“…SWCNTs have only a single layer of graphene, while MWCNTs are made up of multiple rolled layers of graphene. CNTs can be treated by acid, such as nitric acid and sulfuric acid, and potassium permanganate, to form oxidized CNTs [75][76][77][78]. Compared to CNTs, oxidized CNTs become polar and easy to disperse in water.…”

Carbon nanoadsorbents have attracted tremendous interest for metal ion removal from wastewater due to their extraordinary aspect ratios, surface areas, porosities, and reactivities. However, challenges still exist as they suffer from subpar dispersion and recovery, tending to aggregate, and so on. Thus, significant research efforts focus on modification of these carbon nanomaterials to increase the dispersions and recoveries, while maintaining or even enhancing the desirable properties. This review aims to give an in-depth look at recent and impactful advances in metal ion adsorption applications involving these modified carbon nanostructures. Here, the advanced design and testing of modified carbon nanostructures for metal ion removal are emphasized with comprehensive examples, and various adsorption behaviors and mechanisms are discussed, which are hoped to help the development of more effective adsorbents for water treatment.

“…One attractive property of CNTs for water purification is their increased capacity to remove heavy metals from solution compared to AC [118][119][120]. Available surface area and surface functional groups are the key determining factors that influence this improved adsorption and these parameters have been the focus of much research [121].…”

Abstract:To ensure the availability of clean water for humans into the future, efficient and cost-effective water purification technology will be required. The rapidly decreasing quality of water and the growing global demand for this scarce resource has driven the pursuit of high-performance purification materials, particularly for application as point-of-use devices. This review will introduce the main types of natural and artificial contaminants that are present in water and the challenges associated with their effective removal. The efficiency and performance of recently developed materials for water purification, with a focus on activated carbon, carbon nanotubes and graphene will be discussed. The recent advances in water purification using these materials is reviewed and their applicability as point-of-use water purification systems discussed.
