| Abstract: | The sample is treated with water, acid(hydrochloric acidor nitric acid)and hydrofluoric acid. Sodium content in carbon-whitehad been determinated using flame photometry and atomic absorption spec-trometry. Results show that the water treatment is low obviously, acidand hydrofluoric acid treatment is satisfactory. Besides, effect of determi-nation of sodium in the ordinary glass container storaged test solution isexamined. |
