“…The maximum adsorption capacity by fitting Langmuir model ( q m ) was 113.63 mg g −1 . The adsorption capacity of the WSCC–oSWCNTs nanocomposite was also compared to those of other adsorbents from the literature (Table 2) 2,18,29,54–62 for Pb( ii ) removal from water. These observations indicate the potential of WSCC–oSWCNTs nanocomposite for Pb( ii ).…”

Water pollution caused by trace metals poses a serious risk to human health and the environment. An ecofriendly approach was implemented to clean up these pollutants, in which an inexpensive and ecofriendly hydrogel composite was synthesized using Tectona grandis (teak wood) sawdust. Firstly, lignin was extracted from the sawdust by a mild acidolysis process. The extracted lignin was subsequently treated with montmorillonite for the synthesis of the hydrogel. Plausible methods for the process of free radical graft polymerization were theorized. When the hydrogel composite was utilized for the removal of Pb(II), Cd(II), Hg(II), and As(III) ions from the water, it exhibited high adsorption capacity (11.92, 11.58, 11.85, and 11.57 mg g −1 , respectively) for all the trace metals. Kinetics and modeling studies revealed that the adsorption kinetics was better explained by a pseudo-second-order kinetic model, and at equilibrium, adsorption followed a Langmuir isotherm. It was interesting to note that the synthesized hydrogel possessed excellent reusability and desorption and regeneration properties. Ion exchange and chelation properties of the hydrogel were probably responsible for the adsorption mechanism. The regenerated hydrogel showed >50% removal efficiencies even after five cycles, showing economic feasibility of its application at a large scale.

“…For example, chemical precipitation produces a large amount of sludge which is difficult to treat and does not play a role at lower heavy metal concentrations, the universality of the ion exchange method is poor, and membrane separation has problems such as poor membrane strength, short service life, membrane surface fouling and difficult treatment. As a result, many researchers have shown that the adsorption method has merits of high‐efficiency, economic benefits, environmentally friendly 12 . Moreover, it is easy to operate 13,14 .…”

This study is aiming to prepare the porous PBAT/modified zeolite composite by the simple, rapid, and efficient method of preparing them by the solution coating process with modified zeolite as adsorbent, as well as with PBAT as carrying agents and with ethanol as porogenic agent. Some influencing factors for adsorbing PBAT/modified zeolite composite membrane in Lead‐Ion‐Heavy Metal wastewater were researched in this paper, including the effects of zeolite content, modifier type, initial pH, pore‐making agent, adsorption time, adsorption temperature, initial concentration, and feeding quantity. In addition, the adsorption processes of the porous PBAT/modified zeolite composite membrane are studied by means of the adsorption kinetics and adsorption isotherm models. The finding shows the kinetic data were consistent with the pseudo‐second‐order model, and the data fitting of isothermal adsorption experiment is closer to the Langmuir adsorption model, which is a single‐molecule adsorption process and belongs to chemisorption, with a saturation adsorption amount of about 106.3 mg/g. Therefore, zeolite has great prospects for the removal of Pb(II) in wastewater, and provides a theoretical basis for the efficient treatment of heavy metal‐containing wastewater.Highlights A composite film that can effectively remove Pb(II) from water was prepared. The composite exhibits rational pore structure and high specific surface area. This composite has advantages of biodegradability and reproducibility.
