Doped tin dioxide electrodes have been prepared by a standard spray pyrolysis technique. The electrochemical behaviour of these electrodes has been investigated by cyclic voltammetry in sulphuric acid using the Fe2+/Fe3+ redox couple system as test reaction. Oxygen evolution has…

In the industrial obtention of D-a-p-hydroxyphenylglycine the separation of the amino acid is carried out by precipitation and during this process, a mother liquor is produced with a high salt content (phosphates and sulphates) and an amino acid concentration of…
