Enhanced adsorption of Eu(III) from wastewater using Solidago canadensis-derived biochar functionalized by Ca/Al-LDH and hydroxyapatite

Adsorption of polycyclic aromatic hydrocarbons over CuZnFeAl–LDH modified by sodium dodecyl sulfate

“…High molecular weight organic anions can enter the interlayer of LDH, such as DS − whose structure contains an –OSO 3 bond. 42 …”

“…High molecular weight organic anions can enter the interlayer of LDH, such as DS À whose structure contains an -OSO 3 bond. 42 Organic molecules are distributed into the organic phase formed between layers through the partition mechanism. 43 Anionic surfactants intercalate into the interlayer to form a tightly packed hydrophobic microenvironment between the CuZnFeAl-LDH layers, which can signicantly enhance the adsorption of PAHs.…”

Functional utilization of biochar derived from Tenebrio molitor feces for CO2 capture and supercapacitor applications

“…The peak at 2354 cm −1 corresponded to the CO 2 stretching vibration and the band below 600 cm −1 appeared because of the M–X stretching vibration of inorganic halogen salts (such as KCl and CaCl 2 ). 35 Raman spectroscopy was further used to analyze the ratio of crystalline carbon to amorphous carbon in the TMFB and activated TMFB samples. As shown in Fig.…”

Preparation and Characterization of an Invasive Plant-Derived Biochar-Supported Nano-Sized Lanthanum Composite and Its Application in Phosphate Capture from Aqueous Media

“…This invasive plant has harmful impacts on the native environment and the security of human life. − The abundant availability of invasive plants allows the massive production of S. canadensis-derived biochar, which can also provide a viable and economic approach to effectively control this invasive plant. − The adsorption of phosphate by modified biochar prepared from S. canadensis in the post-treatment process has not been studied extensively.…”
