Tea samples treated with Microwave digestion system can greatly reduces magnitude of digestant, and decrease its processing time. Pb in Tea was determined by graphite furnace atomic absorption spectrom- etry.The method is rapid, simple and accuracy. The relative standard deviation of lead was 2.6%-5.1%, the detection limit was 0.082mg/kg.
