- •
Raman is used by first time for adsorption of cyanide on calcined LDHs.
- •
Raman is an effective, accurate and expeditious method for monitoring this process.
- •
Cyanide is adsorbed by a rehydration process based on the “memory effect”.
- •
The metal ratio of the LDH has a crucial influence on the adsorption capacity.
