Photo-catalytic activity has been studied using methylene blue dye as a test contaminant.
The ATD is used as a test contaminant for fuel system components, water filter performance evaluation and other custom applications.
MB was used as a test contaminant since it has been extensively used as an indicator for the photocatalytic activities [43, 44].
The photocatalytic activity of PbS−ZnO LHAs is probed by monitoring the photoreduction of the test contaminant methylene blue (MB) and correlated with ultrafast spectroscopic studies on LHAs.
Photo-catalytic activity of nanocrystals studied using MB dye as a test contaminant enhances with the addition of Mn2+ ions in ZnS nanocrystals upto to optimal concentration (1 at.
If this path is followed by several research groups and the results are discussed with respect to charge/size of tested contaminants, a database would be soon available to boost the optimization of Fe0 filters.
A sample of Sera Micron was analysed by Lancaster Laboratories (Lancaster, PA, USA) for potential contaminants (metals and pesticides), and all tested contaminants were below their limits of quantification for analysis at that facility.
The iron slurry properties (iron particles size and concentration, polymeric stabilizer type and concentration, slurry viscosity) were designed in the laboratory based on several tests (reactivity tests towards contaminants, sedimentation tests and rheological measurements).
In general, toxicity studies with fish eggs require a sufficient number of healthy and freshly fertilized eggs for each concentration and control treatment to assure the gain of reliable dose response relationships of the tested contaminant.
