The Collection and Flame Photometric Determination of Cesium

Traces of cesium can be concentrated from large volumes of water by batch adsorption on ammonium 12molybdophosphate (AMP). Al3+ is used as a flocculant to facilitate collection of the AMP. The solids are dissolved in NaOH, Cs is extracted with a hexone-cyclohexane solution of sodium tetraphenyl boro...

description Traces of cesium can be concentrated from large volumes of water by batch adsorption on ammonium 12molybdophosphate (AMP). Al3+ is used as a flocculant to facilitate collection of the AMP. The solids are dissolved in NaOH, Cs is extracted with a hexone-cyclohexane solution of sodium tetraphenyl boron, and the extract is burned in a flame photometer. The limit of detection is 0.005 mu g Cs per ml of the solution burned. If the collection procedure is applied to an 8-liter water sample, this corresponds to a detection limit of 6 x 10-6 mu g per ml of the water. With minor modifications the procedure can also be applied to sea water, tissue ash, and minerals.
