Does anybody have a method for quantification of potassium ferrocyanide using HPLC with a UV/Vis detector& reversed phase columns?
Why? Particularly when spectrophotometry and titration are so effective. Is your sample matrix interfering with these methods?
See the attached article below:
Article Study on the determination of ferricyanide in ferrocyanide u...
What is the sample volume and how many samples you have to run? Probably, other cost effective methods might be available rather using high cost HPLC

the product contains multivitamins
when i used titration there is interference
As you asked in the question there is no interference with UV Vis. Did you have a problem with separation of the compound? You might want to try a precipitation method. What is the color of your compound?
Udaya Jayasundara yes I have a problem with separation of the compound (potassium ferrocyanide).
Dear Mahmoud Abdelhakem , we used the following recipe successfully to determine both hexacyanoferrates in wine:
Columns: Dionex IonPac NS1 with Guard column
Eluent: 2mM TBAOH, 0.3mM Na2CO3, in 40% Acetonitrile
Flow: 1 mL/min
Detection: suppressed conductivity (external water regeneration), Dionex ASRS
Also, one can try UV, but suppressed conductivity is the more selective alternative.
The column is a not functionalized material with RP properties. In contrast to conventional silica-based material, the efficiency will be lower, but the selectivity gain is significant.
I hope this helps.
Good luck with your research,
Detlef.
Detlef Jensen than u for ur answer
Can u suggest Equivalent column other than Dionex IonPac NS1 ?
