The Anodamine residual method avoids the use of common dyes like Bengal Rose or Eyosin based indicators. Our method is non-specific to Anodamine but measures rather organic content.
Accordingly, reducing agents, natural organics (polysaccharides and humic acids) all act as interferences. However – since these low molecular weight organics are typically completely destroyed by the high temperature cycle, they are not a practical interference.
The Anodamine mechanism of treatment does not rely on the
application of thermally unstable neutralizing or alkalizing amines (see sections elimination of oxide transport problems and thermal stability) removal of oxygen or operation of the cycle under a reducing environment as per AVT(R) guidelines.
Elimination of reducing agent is applicable to all boiler designs, metallurgies, pressures and temperatures. With this in mind, little interference exists in the determination of Anodamine residuals in a high temperature boiler cycle.
After a simple digestion, the color complex formed is then read with a suitable spectrophotometer. The absorbance is directly related to the concentration of organics in the sample.
