Abstract: A solution to be treated by ion exchange is continuously introduced into the bottom of the first of a series of ion exchange vessels containing respective adsorption columns of an appropriate, particulate, ion exchange material, and is passed successively through the subsequent ion exchange vessels of the series, so that such solution flows continuously upwardly through each adsorption column, thence to the bottom of the next column, and is finally discharged from the last column of the series as fully treated solution. The loaded adsorption column is removed from the first vessel of the series, usually to eluting means for regeneration, and the other adsorption columns are transferred from vessel to vessel up the line, the adsorption column of the last vessel of the series being replaced by substantially unloaded ion exchange material, usually eluted material from the adsorption column of the first vessel of the series. The cycle is repeated continuously throughout any given period of operation of the method. The eluting means preferably comprises one or more conventional fixed bed ion exchange vessels, with or without a holding vessel in advance thereof, and there is preferably an excess of ion exchange material at this stage so that, in conjunction with such vessel or vessels, there is a metering of ion exchange material circulating batchwise through the system countercurrent to the solution.
