| Abstract: | A method is described for the rapid determination of elements Ca, Mg, Na, Fe, Mn in the carbonate fraction of marine sediments by atomic absorption spectrophotometry. The sample is dried, ground and weighted, then 103mol/m3 hydrochloric acid is added at room temperature for digestion. After the solution is filtered, potassium chloride is added to the filtrate to 0.5% of K+ as a releasing agent. All elements are analysed with flame atomic absorption spectrophotometer model WFD-Y2 (made in Beijing, China).The recovery rate and the relative standard deviation were tested to be within 87.6-105.1% and <3% respectively.The method is time-saving, accurate an reliable. |
