A decrease in the removal yield at upper optimum pH for each cation is due to the formation of soluble hydroxy complexes [22].
The difference in the removal yield of different cations at the same conditions such as initial concentration, adsorbent dose, and contact time may be attributed to the difference in their chemical affinity with respect to SH groups on the surface of the adsorbent [23].
A significant overlap exists in the removal yields for magnetic and density separation of the different inorganic contaminants, ranging from 29% to 72% depending on the contaminants and the soil fraction.
The convergence in yields reflects mainly the removal of exchange-rate risk since the creation of the single currency, but that still leaves default risk.
On this occasion, treatment with TASF resulted in the removal of both protecting groups to provide callipeltoside C (3) (Scheme 29) in 57 % yield (2 steps).
The same electro-Fenton systems also yield the overall removal of triclocarban in acetonitrile/water mixtures, giving rise to urea, hydroquinone, chlorohydroquinone, 1-chloro-4-nitrobenzene and 1,2-dichloro-4-nitrobenzene as primary intermediates.
The fungus succeeded to remove approximately 400 mg/L initial phenol concentration with 61.5%, 98.7% and 100% removal yields in the medium containing 1 g/L glucose, 1 g/L apple pomace sugar and 1 g/L carrot pomace sugar respectively at pH 6.
This study proposes a deinking selectivity concept that considers both ink removal and fiber yield in determining the performance of deinking operations.
There are several advantages associated with using thermotolerant yeasts, such as cost reduction associated with cooling fermentation vats, obtaining higher yields in saccharification, continuous removal of ethanol, and decreased risk of bacterial contamination (Banat et al. 1998; Limtong et al. 2007).
Ring-closing olefin metathesis covalently captures the entwined structure in high yield and subsequent removal of the cations affords the metal-free Solomon link.
