| The extractant, which is determining the capacity of the resin, has to have a high selectivity and needs to be chemically and physically stable. |
|
| The extractant is adsorbed on the surface of an inert support and corresponds to the organic, stationary phase. |
|
| Extraction of valeric acid was significantly enhanced by the presence of a carboxylic acid in the toluene extractant, or the aqueous feed, or both. |
|
| Potassium hydroxide may also be used as an extractant but may not be used to fortify the potassium analysis. |
|
| The first step to designing a soil test program is selecting the chemical extractant. |
|
| The tungsten is then stripped from the extractant into an ammonia solution containing ammonium tungstate. |
|
| During the countercurrent flow of the extractant through the solution, tungstate ions transfer from the aqueous phase to the organic phase. |
|
| Process for isolating polyorganosiloxanes from an aqueous dispersion, which comprises separating the polyorganosiloxanes from the water in dissolved form by means of an extractant. |
|
| The remaining sodium tungstate solution can be further purified by a liquid ion-exchange process, using an organic extractant consisting of 7 percent alamine-336, 7 percent decanol, and 86 percent kerosene. |
|
| A number of chemical reagents, including sulfuric acid, hydrochloric acid, and solvent extractant, will be used for mineral processing as shown in Table 2, which includes recommended disposal methods for each chemical. |
