    摘要: The invention relates to a sorbent for removing metabolic waste products from a dialysis liquid, the sorbent comprising a soluble source of sodium ions. The sorbent comprises an ion exchange system which converts urea to ammonium ions and which is configured to exchange ammonium ions for predominantly hydrogen ions and to exchange Ca, Mg, and K for predominantly sodium ions. The soluble source of sodium ions overcomes an initial drop in sodium concentration in regenerated dialysate. When used in conjunction with an infusion system configured to utilise exchange of Ca, Mg and K for sodium during dialysate regeneration a desired sodium ion concentration can be maintained.

    摘要: In order to reduce the contamination of scandium oxide products, the present disclosure provides a process for removing at least one metal contaminant from a scandium (Sc) concentrate. The process is based on contacting the Sc concentrate with an ion exchange resin to obtain a purified Sc eluate or raffinate. The first ion exchange resin and the second ion exchange resin are strong acid cationic resins with sulfonic acid functional groups in a potassium or sodium form. The purified Sc eluate or raffinate can be used to make scandium oxide products having a reduced amount of metal ion contaminants.

    摘要: Polymeric mono-, di-, tri- and tetra-sulfides are described having an organopolysiloxane base structure of the units:R.sup.1 --S.sub.1-4 --R.sup.2 (1)wherein R.sup.1 and R.sup.2 may be the same or different and represent a group of the formula:R.sup.3 --SiO.sub.3/2 (2)and which base structure may further optionally contain the heteroatoms titanium or aluminum,wherein R.sup.3 is an alkylene group and the free valencies of the oxygen atoms are saturated by silicon atoms of additional groups of formula (2), optionally with the insertion of cross-linking silicon-, titanium- or aluminum compounds,whereby the ratio of the silicon atoms in formula (2) to the silicon-, titanium- and aluminum atoms of any cross-linking agent may range from 1:0 to 1:10. In addition, processes for obtaining the sulfides and the use of these sulfides for the removal of certain ions from solutions are described.
