| titleOfInvention | Process of removing ions from solutions using a complex with sulfur-containing hydrocarbons also containing electron withdrawing groups bonded to a solid hydrophilic matrix |
| abstract | A method for the removal and concentration of desired ions such as Pd(II), Ru(III), Pd(IV), Au(III), Au(I), Ag(I), and Hg(II) from a multiple ion source solution which may contain larger concentrations of other undesired ions including H+ com-prises bringing the source solution into contact with a compound comprising a sulfur and electron withdrawing group con-taining ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The sulfur and electron withdrawing group containing ligand portions(s) of the compound has an affinity for the desired ions to form a complex thereby removing the desired ions from the source solution. The desired ions are removed from the compound 4y contacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired ions than does the sulfur and electron withdrawing group containing ligand portion of the compound. The process is useful in removing desired or unwanted ions from acidic waste streams, metal refining streams, and other industrial or environmental streams. The invention is also drawn to the sulfur and electron withrawing group containing ligands covalently bonded through a spacer grouping to a hydrophilic inoragnic solid support material. |
