根据润滑油中磨损金属含量变化,可监控各类发动机运转,并预测发动机内磨损情况。采用火焰或非火焰原子吸收方法,并配合不同的化学预处理测定磨损金属,文献已有报导,但操作烦琐,需时较长。我们采用了新的酸性混合溶剂稀释油样,直接火焰原子吸收测定各类润滑油中磨损金属铁、铜。该混合溶剂具有可使用无机标样,易于溶解和分散磨损金属,毒性小、灵敏度 According to changes in wear metal content in lubricants, can monitor various types of engine operation, and predict engine wear. The use of flame or non-flame atomic absorption method, and with different chemical pretreatment determination of wear metal, the literature has been reported, but the cumbersome operation, takes a long time. We use a new acid mixed solvent diluent oil samples, direct flame atomic absorption measurement of various types of lubricants wear metal iron, copper. The mixed solvent has the potential to use inorganic standard, easy to dissolve and disperse the wear metal, low toxicity, sensitivity
