Chromatographic recovery and purification of natural phytochemicals from underappreciated willow bark water extracts
(Elsevier, 2020-12-26)
Willow (Salicaceae) bark contains a variety of antioxidant phytochemicals depending mainly on the hybrid. In this study, hot water extraction of willow bark was coupled with a sequential preparative scale chromatography ...
Intermittent recycle-integrated reactor-separator for production of well-defined non-digestible oligosaccharides from oat β–glucan
(Elsevier, 2020-12-31)
A recycle-integrated reactor-separator system was studied experimentally and based on simulations for the acid-catalyzed depolymerization of oat beta-glucan polysaccharide. The aim was to produce oligosaccharides with ...
Recovery of rare earth elements from phosphogypsum waste in resin-in-leach process by eluting with biodegradable complexing agents
(Elsevier, 2021-02-02)
Phosphogypsum waste is a potential, secondary rare earth element (REE) source that is available in very large volumes. Extraction and purification of REE from this complex waste was studied using resin-in-leach (RIL) ...
