Some methods of sample decomposition were applied and compared each other for the determination of eight elements in Chinese cabbage. After the mixing of frozen sample with water in a kitchen mixer, the representative aliquots of sample suspension were served for such pretreatments as dry ashing in an electric furnace, wet digestion with nitric acid and hydrogen peroxide, sealed Teflon vessel method (I and II) with nitric and perchloric acids, and leaching with hot and dilute hydrochloric acid. Sodium and potassium were measured by flame emission spectrometry. Magnesium, calcium, copper, iron, manganese, and zinc were measured by atomic absorption spectrometry by one-drop method. The leaching method with hydrochloric acid gave good analytical results in accuracy and reproducibility except for iron. The method can be recommended for a practical use because of its easy and simple operation and low cost.
