title: [Simultaneous determination of heavy metal elements in footwear materials by ICP-AES].
abstract: Footwear materials were treated by the digestion method of carbonization-crack-HNO3-HClO4 dissolution, and the heavy metal elements in these materials were simultaneously determined in the same treated solution. Factors such as the selection of analytical wavelength and the interference of matrix and coexistent elements were studied. The method was secure, convenient, rapid and accurate. The recovery rates of the procedure were between 92.0% and 102.0% with RSDs between 1.0% and 4.6%.
