| Abstract: | A determination of Er and Eu in doped crystals YVO_4 has been carried out by ICP-AES method. The sample is decomposed with H_2SO_4. A satisfactory results has been found with the rate of recovery of 98% -104 % and 96% -105% for Er and Eu respectively, the relative standard deviation within 3%. The correspondent internal standard elements is selected. The effects of the concentrations of H_2SO_4 and the matrix on the lnie intensively of Er and Eu have been investigated. |
