Flotation concentration of trace elements while analyzing water

The review includes basic studies of the recent 10-15 years on application of the flotation methods to concentrate taces of elements (Cd, Mo, W, V, U, In, ets.) for their determination in waters. Procedures are presented which are based on the codeposition of trace elements on the inorganic and organic collectors, on their sorption on fine-disperse ion exchangers, on the process of ionic flotation. Merits and prospects of the methods for flotation concentration of element traces to analyze waters are noted
