The ferricyanide test confirmed that the brown colouration of the water extracts was closely associated with tannins. |
|
For some samples a mixture of ferricyanide and ferrocyanide were added to the pellet. |
|
The latter spectrum was measured after reduction of cyt-c with ascorbic acid, followed by oxidation using ferricyanide. |
|
Red cells are lysed and potassium ferricyanide oxidizes hemoglobin to methemoglobin, which combines with potassium cyanide forming cyanmethemoglobin. |
|
The presence of antioxidants in the test sample will reduce the ferricyanide to ferrous form. |
|
Figure 03 the plant extracts was identified by using the potassium ferricyanide reduction method. |
|
When I was growing up my chemistry set had a lot of potentially harmful chemicals like copper sulfate and potassium ferricyanide. |
|
Residual concentrations of phenol were defined by direct photometric method using 4-aminoantipyrene and alkaline potassium ferricyanide. |
|
They filled an electrochemical cell, essentially two glass jars joined with a glass tube, with an electrolyte solution of potassium ferricyanide and potassium chloride. |
