Temperature Effects on Electronic Spectral Absorptions of Aqueous Electrolyte Solutes I: An Optical Microautoclave

Volume 38, Number 4 (Aug. 1984) Page 575-578

Toy, Madeline S.; Stringham, Roger S.; Floyd, Mark S.; Passell, Thomas O.


A high-temperature optical microautoclave for maintaining aqueous solution at elevated temperatures and pressures is described. The apparatus is being used to monitor the chemical processes taking place during temperature cyclings. Some spectra of copper(II) and iron(II) solutions are presented as examples up to 200°C and 15.3 atm estimated pressure.
