| Abstract: | A procedure of direct determination of molybdenum in soil and sediments of hydrographic net by graphite furnace atomic absorption spectrometry was described. The samples were digested in a Teflon crucible by treatment with a mixture of HClO_4-HF. Nitric acid was used for the final dissolution of digested samples. The sensitivity of the method had a characteristic mass of 10 pg/1 %A. The cofficient of variation obtained for the method was 4. 5鈥?.4%. The recovery ratio was 102-107%. |
