"Determination of 888\" concentration
Thread Content
When using “888” as a desulfurization catalyst, it is often difficult to determine its content; many manufacturers do not conduct such analyses. Here, a method is provided for reference, in the hope that it will be useful to everyone. Method: It can be determined using a P-E403 type flame atomic absorption spectrometer. Mainly, instruments are used to determine the cobalt (Co) content in the desulfurization solution, and then multiplying this value by 16.5 gives the content of “888” (Note: the coefficient of 16.5 is an average value obtained through multiple calculations)
It’s not just 888 that uses this method; all cobalt phthalocyanine series products can use it, though the coefficient is not necessarily 16.5 – it needs to be determined specifically.
