Sentence examples for severe leaching from inspiring English sources

Preliminary experiments showed that symmetric tetrachloroperylene bisimides with two PET functionalities show excellent acid base sensitivity in organic solvents, but application in a hydrogel matrix was compromised by severe leaching of the dicationic protonated form.

In case of 2a, 2b, 2d and 3, no leaching into the aqueous solution is detectable after 24 h in basic (pH > pKA + 2) and acidic buffers (pH < pKA − 2) which is in contrast to severe leaching observed for the indicators bearing two PET functionalities.

Using traditional liquid-phase oxidations this is not possible due to severe metal leaching.

One of the key hindrances on development of solid catalysts containing cobalt species for partial oxidation of organic molecules at mild conditions in conventional liquid phase is the severe metal leaching.

As CBV720 was produced via a severe dealumination process and leached by a mineral acid, the resultant catalyst has a small number of acid sites.

High surface area and larger pore volume, due to the more severe dealumination process and acid leaching, reduced the hard coke content, thus slowing the deactivation rate.

In addition, the high surface area and large pore volume shown in Table 3, due to the more severe dealumination process and acid leaching, reduced the hard coke content and thus the deactivation rate.

It is shown that these materials can withstand severe hydrothermal conditions and that the leaching of the catalytic active species in liquid media is very strongly reduced.
