PURPOSE:To purify an extract of seaweeds useful as foods, etc. in high water permeability, by introducing an aqueous solution of high polymer polysaccharide extracted from seaweeds to a hollow fiber type ultrafiltration module, etc., keeping the shear rate at the outlet end under a specific condi...
A stable isotopic dilution method and a fluorimetric method for the measurement of the concentration of uranium in sea water are described. In both methods the uranium is extracted from the sea water into chloroform using 8-hydroxyquinoline. 237U is used as a tracer in the fluorimetric method. ...
2.1 Chemistry of boron in water Boron species are found predominantly in aqueous solutions, depending on the boron concentration, pH, and temperature of the solution (e.g., boric acid, which is a very weak Lewis acid (Eq. (1)) and its conjugate base (B(OH)−4) at a low boron conc...
