“…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 ).…”

“…Moreover, it would damage various organs and cause neurological dysfunction, anemia, kidney damage, and so on (Mouni et al 2011;Ifthikar et al 2017). According to report of World Health Organization (WHO) (Naushad et al 2021), the concentration of Pb(II) ions in drinking water could not exceed about 10 µg/L. Therefore, some conventional separation technologies for Pb(II) removal are reported, such as ion-exchange, ltration membranes, electrolysis deposition, co-precipitation and coagulation processes (Cui et al 2015;Huang et al 2018).…”

The large amounts of heavy metal from landscape wastewater have become serious problems of environmental pollution and risks for human health. It affects the growth of plant and aquatic, and leads to the destruction of landscape. Therefore, the development of e cient novel adsorbent is a very important for treatment of heavy metal. A low-cost and easily obtained agricultural waste (Peanut Shell) was modi ed by nanoscale Fe 3 O 4 particles. Then, the functionalized porous nanoscale Fe 3 O 4 particles supported biochar from peanut shell (PS-Fe 3 O 4 ) for removal of Pb(II) ions from aqueous solution was investigated. The characterization of PS-Fe 3 O 4 composites showed that PS from peanut shell was successfully coated with porous nanoscale Fe 3 O 4 particles. The pseudo second-order kinetic model and Langmuir model were more tted for describing the adsorption process of Pb(II) ions in solution. The maximum adsorption capacity of Pb(II) ions removal in solution by PS-Fe 3 O 4 composites could reach 188.68 mg/g. The adsorption process of Pb(II) ions removal by PS-Fe 3 O 4 composites was a spontaneous and endothermic process. The adsorption mechanisms of Pb(II) ions by PS-Fe 3 O 4 composites were mainly controlled by the chemical adsorption process. They included Fe-O coordination reaction, coprecipitation, complexation reaction and ion exchange. PS-Fe 3 O 4 composites were thought as a low-cost, good regeneration performance and high e ciency adsorption material for removal of Pb(II) ions in solution.

“…3,4 Humans can suffer from long-term brain damage when the Pb(II) concentration is over 50 mg L À1 in drinking water; therefore, the World Health Organization has stated that the allowable limit of Pb(II) content in drinking water is 10 mg L À1 . 5 To date, a variety of technologies for removing Pb(II) from wastewater have been developed, 6 including coagulation-occulation, adsorption, membrane separation, 7,8 ion exchange and electrochemical precipitation. 9 The adsorption method stands out from the rest due to its economic performance, high efficiency and simple operation.…”
