| Abstract: | The latest developments of RoHS directive and the REACH regulation are summarized in this paper. Determination of lead, mercury, cadmium, chromium in television unit samples using XRF is established. The samples are prepared by microwave assisted acid digestion, which can reduce the matrix interference in the testing. This method can be used in determination of four metals and judgment of 47 SVHC in REACH regulation. It provides effective and less consumption for the determination in RoHS directive and the REACH regulation. |
