| Abstract: | This paper dicusses various reaction conditions based on generating the precipitation BaSO~(2-)_4 by means of reacting SO~(2-)_4 with the precipitator Ba~(2+) and determines exactitude of determination methods. The two methods of indirect determination of sulfate (SO~(2-)_4)in natural water are settled by comparative analysis of AAS and ICP-AES with satisfactory results. |
