| Abstract: | Adopt a microwave to dispel system processing the soil sample, can deplete to digest the reagent dosages and sample treatment time. Two ammoniums and hydrogen nitrate magnesium work blend base with phosphoric acid hydrogen experiencing and observing the improvement agent, may raise dust spending the temperature, remove base experiencing and observing a disturbance. Method is simple and convenient, the fleetness, accurate degree are high. The relative the cadmium admeasurement result standard deviation is2.1%-4.5% ; Inspect up out a limit being 0. 007 mg/kg. |
