摘要:

An ion exchange sample probe using Ammonium Pyrrolidine Dithiocarbamate (APDC)-Polystyrene (PS) film for trace metal pre-concentration has been developed. The polymer-ligand mixture is coated onto glass plates and air-dried to form films with 10 to 20μm thick. The sample probe is immersed in the sample solution to preconcentrate metal ions onto the film. The film is then laser sampled for quantitative elemental analysis using ICP-AES. Using the ion exchange sample probe, sensitivity is enhanced.
