To overcome the limit of old style filter
They do not work well at some circumstance.
The combination of activated carbon and zeolite has limit.
To improve performance of filter
To improve selectivity of absorbance.
To improve efficiency of filter.
- Measure both concentration of toxic substance.
- Compare the before and the after
- Test all three phase of toxic material
carbon.). For example, a 10nm size particle was selected Fig.3a and a spot analysis was conducted. From the acquired spectrum Fig.3b, the particle was identified as another Nb precipitate. Prior to this study, it was certain that Nb precipitates as particles above 50nm in steel, but identifying precipitates below this size was not clarified. However, from this analysis conducted on carbon extract
