Novel reed + deep eutectic solvent-derived adsorbents for recyclable and low-cost capture of dyes and radioactive iodine from wastewater

Abstract

Green and low-cost capture of radioactive iodine is urgent due to nuclear leak and nuclear disaster. Deep eutectic solvents (DESs) are deemed as green solvents of 21st century with high...

Sustainable Tandem Strategy for Recycling the Lithium-Ion Battery Cathode and Treating Waste by Cheap and Biocompatible Deep Eutectic Solvents

“…In this equation, y and t mean removal efficiency (%) and time (h), respectively, while a , b , and c are the fitted parameters. Chen et al also found that the adsorbent rate of iodine, methylene blue, and rhodamine B is higher at first and then slower . With regard to the dissolution of the LIB cathode, the dissolution rate also decreases with the time .…”

“…Chen et al also found that the adsorbent rate of iodine, methylene blue, and rhodamine B is higher at first and then slower. 50 With regard to the dissolution of the LIB cathode, the dissolution rate also decreases with the time. 31 The dissolution of rare earth oxides also shows a faster rate in the beginning followed by a subsequent lower rate.…”

Unexpectedly Superhigh Toxicity of Superbase-Derived Deep Eutectic Solvents albeit High Efficiency for CO2 Capture and Conversion

“…1,8-Diazabicyclo­[5.4.0]­undec-7-ene (DBU, 99%), 1,5-diazabicyclo[4.3.0]­non-5-ene (DBN, 98%), ethylene glycol (EG, 99%), glycerine (Gl, 99%), benzyl alcohol (BnOH, 99%), benzoic acid (BEN, 99.5%), glutaric acid (GA, 99%), malonic acid (MA, 99.5%), and oxalic acid (OA, 99.5%) were purchased from Beijing Innochem Technology Co., Ltd. The synthesis procedure of superbase-derived DESs was analogous to previous reports. ,,,− The different types of HBD and HBA were mixed according to the fixed molar ratio and magnetically stirred for 24 h until the mixtures show a clear state. The types of HBD involved in this study include EG, Gl, BnOH, BEN, GA, MA, and OA, while HBA includes DBU and DBN.…”

“…Superbase-derived DESs could also show good performance for lignin dissolution . Chen et al utilized superbase-derived DESs as raw materials and pore-foaming agents in combination with reeds for the preparation of carbon materials to remove pollutants from wastewater . In addition to superbase-derived DESs, superbase-derived ILs also show favorable performance of CO 2 capture and conversion. − …”

“…50 Chen et al utilized superbase-derived DESs as raw materials and pore-foaming agents in combination with reeds for the preparation of carbon materials to remove pollutants from wastewater. 51 In addition to superbase-derived DESs, superbase-derived ILs also show favorable performance of CO 2 capture and conversion. 52−54 However, for superbase-based DESs, most of the previous studies had focused on their application in various fields, while there is no report on the investigation of the toxicity of superbase-based DESs.…”
