Abstract:
Soluble aluminium (Al(sl)) in high silicon alloys is determined by electrolytic dissolution flow injection analysis (ED-FIA) and inductive coupled plasma with optical emission spectrometry (ICP-OES). Skipping the time consuming sample preparation known from acid hydrolysis reduces the required time per determination from 15 to 4 min. A new calculation procedure is used to compensate the discrepancy in matters of dissolution between acid hydrolysis and electrolytic dissolution. Samples with a known silicon content (2,5 and 3,1 wt%) are used to determine the differences of dissolved material and to calculate a correction factor. In a working range of 200-350 ppm aluminium in high silicon steel, there is a standard deviation of 7 ppm for a measurement series of 19 samples (max deviation 19 ppm).

Electrolytes: van't Hoff Factor
The colligative properties of a solution depend only on the number, not on the identity, of solute species dissolved. The concentration terms in the equations for various colligative properties (freezing point depression, boiling point elevation, osmotic pressure) pertain to all solute species present in the solution. Nonelectrolytes dissolve physically without dissociation or any other accompanying process. Each molecule that dissolves yields one...
