Dithiocarbamate modification of activated carbon for the efficient removal of Pb(ii), Cd(ii), and Cu(ii) from wastewater

Abstract

In this study, dithiocarbamate functionalized activated carbon (DTC-AC) was synthesized with nitric acid, tetraethylenepentamine (TEPA), and carbon disulfide (CS2). N2 adsorption-desorption technology, SEM, FTIR, and elemental analysis demonstrated the successful...

Regulating the particle sizes of NaA molecular sieves toward enhanced heavy metal ion adsorption

“…1 Furthermore, lead damages the kidneys, liver, reproductive system and brain function. 2 A buildup of heavy metal ions can harm the body and its internal organs, 3,4 and it can even result in cancer. 5 Therefore, it is essential to explore ways to treat heavy metal ion pollutants in wastewater.…”

“…The maximum adsorption of Pb( ii ), Cd( ii ) and Cu( ii ) by DTC–AC was 203.36 mg g −1 , 102.89 mg g −1 and 53.13 mg g −1 , respectively. 3 Jin et al synthesized l-cysteine functionalized magnetic hollow MnFe 2 O 4 nanorods (H-MnFe 2 O 4 -Cys) for the purpose of removing heavy metal ions, specifically Cr 6+ and Pb 2+ from aqueous solutions. The adsorption capacities of H-MnFe 2 O 4 -Cys for Cr 6+ and Pb 2+ were determined to be 268.86 mg g −1 and 291.07 mg g −1 , respectively.…”
