Title: Determination of Cadmium in Tea by Microwave Digestion-Graphite Furnace Atomic Absorption Spectrometry
Abstract: Tea samples were treated with microwave digestion system.The results showed that this method cluld greatly reduce magnitude of digestant,and decrease its processing time.Cd in tea was determined by graphite furnace atomic absorption spectrometry.The method was rapid,simple and accuracy.The relative standard deviation of lead was 8.9%~12.5%,and the detection limit was 0.002 mg/kg.
