| titleOfInvention | Selective adsorbents for metaloxy and metalloidoxy anions |
| abstract | A selective adsorbent for metaloxy or metalloid oxy anions comprises a cross-linked alkenyl aromatic polymer to the aromatic nuclei of which are bonded numerous polyol ether groups of formulae -CnH2n-O-Z or (-CnH2n-O-)2Z where n is 1-4 and Z is a polyol substituent group derived from sorbitol, mannitol, dulcitol, talitol, arabitol and/or ribitol. The adsorbent may be a styrenedivinylbenzene copolymer to aromatic nuclei of which sorbitol ether groups are attached via methylene groups. The adsorbent may be made by reacting a cross-linked alkenyl aromatic polymer containing quaternary ammonium groups or sulphonium groups, e.g. polymeric vinylbenzyl dimethylsulphonium or trimethylammonium chloride, cross-linked with divinylbenzene, with the alkali metal salt of the above polyols, or with the polyol in the presence of an alkali metal hydroxide in proportion to the ion exchange capacity of the resin.ALSO:Metal oxy or metalloid oxy anions are removed from aqueous solutions by contacting with an unsoluble adsorbent which comprises a cross-linked alkenyl aromatic polymer to the aromatic nuclei of which are bonded numerous polyol ether groups of formulae -CnH2n-O-Z or (-CnH2n-O-)2Z where n is 1-4 and Z is a polyol substituent group derived from sorbitol, mannitol, dulcitol, talitol, arabitol and/or ribitol. The oxy anions are borate, gallate, stannate, plumbate, arsenite, germanate and tellurate, and may be a mixture thereof. In examples borate was adsorbed from an aqueous solution containing NaCl and Na2B4O7. 10H2O acid from an aqueous solution also containing magnesium chloride; TeO4 = from an aqueous solution of K2TeO4.2H2O; arsenite from an aqueous solution of Na2As2O4 and Na2SO4; and SnIV, GaIII and PbIV oxy anions were adsorbed from an aqueous solution containing Na2SO4, ZnSO4, NaOH, stannate, plumbate, gallate, selenate and arsenate. |
