DIRECT DETERMINATION OF STRONTIUM IN SEAWATER BY ATOMIC ABSORPTION SPECTROSCOPY
Abstract:
A method for direct determination of strontium in natural seawater with atomic absorption spectroscopy using air-acetylene flame is described. Since a standard solution prepared with artificial seawater has been used, the effect of competing ions jn natural seawater on the absorption of strontium can be eliminated. A rapid and simple analytical method is developed, with a relative error less than 0.2mg/L and a recovery in the range of 100-103%.
