摘　　要：通过制备干漆膜,采用AAS(原子吸收光谱仪)和ICP-OES(电感耦合等离子体发射光谱仪)分别测定了内墙涂料、聚氨酯色漆和聚氨酯清漆中的可溶性铅含量。通过直接称样,再使用盐酸溶液溶解、定容,测定了环氧富锌底漆用锌粉中的总铅含量。比较了这两种仪器的测定结果,讨论了结果差异的形成原因。The soluble lead content of the dry film of interior wall coatings, polyurethane paint and varnish were tested using AAS and ICP-OES instrument respectively. The total lead content of the zinc powder in the epoxy zinc- rich primer were tested after weighting, dissolving with hydrochloric acid solution, constanting volume. The test results of using AAS and ICP-OES respectively were compared. The differences were found out, and the causes of differences were discussed.
