“…However, the techniques are still useful for special available methods in chromatography. The chromatography of inorganic ions has recently been reviewed by Blasius and Augustin (32), and Senyavin (269); a historical review of modern liquid chromatography, by Ettre and Horvath (80), was most interesting. Recent examples of applications in inorganic analysis were the separation of platinum and palladium on silicone rubber foam treated with dimethylglyoxime (113); the use of stannic antimonate papers in dimethylsulfoxide-nitric acid for the separation of 49 metal ions (246); the use of hydrophilic glycol methacrylate gels combined With oxine for trace inorganic analysis (275).…”
