Preparation of chitosan-coated polystyrene microspheres for the analysis of trace Pb(ii) ions in salt by GF-AAS assisted with solid-phase extraction
The content of heavy metals is an important index to measure the quality and safety of salt. However, due to the high content of Na(i) in salt causing a large background interference, it is difficult to accurately analyze trace Pb(ii) through the existing atomic absorption spectrometry. Therefore, i...
