A three-dimensional magnetic carbon framework derived from Prussian blue and amylopectin impregnated polyurethane sponge for lead removal

Preparation of graphene-MoS2 hybrid aerogels as multifunctional sorbents for water remediation

“…This limitation hinders the real industrial wastewater treatment since it normally contains diverse types of pollutants (e.g., heavy metal ions, dyes, oils, and other organic compounds) [12][13][14][15]. Therefore, it is desired to develop new hybrid carbonbased sorbents, i.e., porous carbon networks incorporated with other functional materials to enhance their sorption capabilities and simultaneously absorb multiple types of pollutants from wastewater [16][17][18].…”

Prussian blue and its analogues as functional template materials: control of derived structure compositions and morphologies

“…By heating the PBAs in an inert atmosphere such as Ar, without providing other elements, alloys and metal carbides can be obtained. [13][14][15][16][17]24,62,65,68,70,84,103,104 For example, the treatment parameters used for oxidation in air can be replicated under Ar to produce a metallic alloy/carbon composite. 84 While mild conditions will form alloys and carbon mixtures, the formation of carbides requires higher temperatures (>500 °C).…”

Superefficient Removal of Heavy Metals from Wastewater by Mg-Loaded Biochars: Adsorption Characteristics and Removal Mechanisms

“…After the six types of biochar adsorbed Pb­(II), it mainly existed in the form of Pb 3 (CO 3 ) 2 (OH) 2 (PDF card no. 13-0131), indicating that surface complexation precipitation participates in the adsorption of the three heavy metals …”

“…13-0131), indicating that surface complexation precipitation participates in the adsorption of the three heavy metals. 50 XPS Analysis. To further explore the adsorption mechanisms of the biochars for the three heavy metals, XPS analysis was performed on samples before and after adsorption, as shown in Figure 7.…”
