The release of digoxin and its simultaneous conversion to digoxigenin bisdigitoxoside, digoxigenin monodigitoxoside, and digoxigenin in a USP dissolution test medium were followed by high-pressure liquid chromatography. Two products, Tablets A and B, were manufactured by solvent deposition and simpl

a b s t r a c t Gold dissolution in acidic solutions containing thiourea (Tu) and thiocyanate was studied using linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS) and surface enhanced Raman spectroscopy (SERS). A synergistic response found in that mixed ligand system promot
The effect of chloride ions on the passivity of iron commanded the attention of early electrochemists 1 and has since been investigated many times 2-4. It is generally assumed that, by a mechanism as yet unknown, chloride ions destroy the passive film either locally, as in pitting, or uniformly and
