This is most relevant for the preparation of saltwater media that require upwards of 30 g of salt per litre, as opposed to freshwater media requiring significantly less (<0.3 g L–1). The highest quality reagent salts should be used wherever possible. The use of cation exchange resins to ...

Equation (4) has the potential to predict the DE based simply on the time of weathering of oil. For this study it was applied to various bitumen blends and the conventional crude, Heidrun, but may be applicable to other oils as well. However, some limitations of the function to consider ...
Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, ...
Salinity is also an important factor to consider, since it can affect the efficacy of dispersants, such as COREXITEC®9500A, that are formulated for saltwater environments [23]. In our experiments, the salinity, over spring and summer months, ranged from 25.5 to 30.4 parts-per-thousand (...
