The application of food/agro-waste and spent household products for the environmentally benign separation of thorium

Abstract

Cost effective and environmentally benign separations of thorium from aqueous acidic medium using spent food/agro byproducts have been demonstrated utilizing used tea leaf, coffee powder and coconut leaves. The presence...

Diglycolic Acid Monoamide-Functionalized UiO-66-Based Metal Organic Framework (MOFDGAMA) for Selective Removal of UO22+ and Th4+

“…The sorption isotherm shown in Figure C describes the maximum sorption capacity for UO 2 2+ ≈ 193 mg g –1 and Th 4+ ≈ 227 mg g –1 . Experimentally obtained sorption isotherm data were fitted on Freundlich ( SE4 ), Langmuir ( SE5 ), and Temkin models ( SE6 ) to understand the detailed mechanism of sorption. − Linear regression analysis of Langmuir, Freundlich, and Temkin isotherms shown in Figures S4–S6 reveal that sorption follows the Langmuir chemisorption model. The experimentally obtained “ n ” value from the Freundlich isotherm was higher than unity, indicating the ideal behavior of the sorption process.…”
