Abstract
Hydrous titanium oxides are produced by reacting an alkali metal titanyl oxalate, e.g. potassium titanyl oxalate ((C2O4)2TiOK2.2H2O) with an aqueous solution of an alkali e.g. sodium or ammonium hydroxide. In a preferred method of preparation hydrous titanium dioxide is produced by reacting potassium titanyl oxalate with aqueous sodium hydroxide, the precipitate formed being washed, filtered off, dried in air and then introduced into distilled water, these steps being repeated until no further breakdown of the lumps of precipitate occurs. Oven drying may also be used. Cations scribed on to the material prepared as above may be eluted substantially quantitatively with mineral acid, e.g. hydrochloric acid. In an example the exchange material prepared as above is used to extract the cations of copper, cobalt, nickel, calcium, strontium, sodium, rubidium, caesium, ircu and chromium from 0.1 N aqueous salt solutions. The pH values of some salt solutions used are given: Cu 4.8, Co 3.2, Ni 3.5, Ca 12.5, Sr 12.8. The exchange material is stated to be operable at elevated temperatures, e.g. up to 400 DEG C., and in examples temperatures used are 25-60 DEG C. In two experiments the exchange material is heated to 200 DEG and 400 DEG C. before use. The exchange material may be used in columns.ALSO:An hydrous oxide of titanium is used in columns as a cation exchanger in the hydrogen form. Comparisons are made with zirconium and thorium hydroxides as exchangers.
