asthmatic samples: 1) the insoluble phases of the CF samples were precipitates rather than gels; and 2) the ratio of BGA units in the two phases indicated that the CF insoluble phases contained only traces of mucin; essentially all of the TBM in the CF samples was in the soluble phase....

to form an insoluble hydroxide precipitation such as Cr (OH)3. It was found that lime precipitation is one of the most effective methods to remove Cr from wastewater [175]. However, the traditional precipitation methods have limitations. For examples, the obtained...
[1,17]. In either case, conjugation of the carboxyl groups to amino groups can be mediated by water-soluble carbodiimide or other coupling agents[18], Alternatively, carboxyl groups can also be converted into their active esters[6,18]or into the corresponding azides for coupling to the ...
Alunite is not very soluble in water and, as such, many mineral recovery processes involve caustic leaching of the ore to solubilize the potassium and aluminum values into the leach liquor from which they are subsequently separated and recovered. U.S. Pat. Nos. 3,983,211; 3,890,425; 3,...
The present invention is directed to maleamic acid derivatives of water soluble polymers, to chemically stable water-soluble polymer succinamic acid-active agent conjugates, and to methods for reproducibly preparing, characterizing and using such polymer reagents and their conjugates.Inventors...
The alkaloids are not appreciably soluble in water; therefore the stock solutions of the alkaloids were prepared in an appropriate volume of distilled acetonitrile. The experiment was performed in a mixture of acetonitrile-water (2% v/v acetonitrile) HCl and NaOH of various concentrations were used...
Unfortunately, no EPR signal of TEMPO could be observed in the presence of PLM I, probably because A7L was soluble at a pH above 5.5 and PLM I had a optimal activity around pH 5. Thus, hydrolysis of the peptide chain did not occur, and consequently, homolysis of alkoxyamine was not ...
This basic pH regime is consistent with Al3+ speciation analysis for the aqueous solutions shown in Figure 7a (and determined by equilibria equations shown in Appendix A), bearing in mind that Al(OH)3 is a sparingly soluble salt. Thus, while most of the Al(OH)3 precipitates out of ...
In this way, the nutrient of soluble α-quartz GeO2 is not permanently in contact with the solution and the nutrient does not transform into the relatively insoluble rutile-type phase. Crystals were grown to a sufficient size (a few cm) in order to measure their physical properties, but ...
