Study on factors affecting rare earth leaching rate in acid leaching process of fly ash
Journal of Theoretical and Applied Sciences, 2022 There is a large amount of enrichment of rare earth elements in Zhungeer coal and coal ash, making it possible to use fly ash as a source for industrial production of rare earth elements. In order to optimize the leaching process of rare earth elements in fly ash and increase the leaching rate, the circulating fluidized bed fly ash of Zhungeer Power ...

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring
Advanced Functional Materials, EarlyView.This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Leach Rate Characterization of Solid Radioactive Waste Forms [PDF]
, 1979 Leach rates for a number of proposed radioactive waste forms have been measured. A neutron activation analysis technique has been used exclusively for these measurements. Leach rates as low as 10-9g/cm2d were easily determined. Problems associated with surface area determination, sample preparation and data interpretation are discussed.
