材质元素对不锈钢杯重金属析出量的影响

Relationship between the precipitation amounts of heavy metals and material elements in stainless steel cups

采用火花直读光谱仪分析了110批次不锈钢杯中C、S、Si、Mn、P、Cr、Ni7种材质元素的含量,同时采用石墨炉原子吸收分光光度法分析了它们的Pb、Cr、Ni、Cd、As5种重金属元素的析出量.研究了不锈钢材质对重金属元素析出量的影响.结果表明,材质元素Ni含量对重金属元素Pb的析出量有显著影响,材质元素C、Si、Mn、P含量对重金属元素Cr的析出量有显著影响,材质元素C、S、Mn、Cr、Ni含量对重金属元素Ni的析出量有显著影响,材质元素Si、Mn、P、Cr、Ni含量对重金属元素As的析出量有显著影响.

The contents of seven material elements C,S,Si,Mn,P,Cr and Ni of 110 batches of stainless steel cups were tested by using a spark direct reading spectrometer.At the same time,the precipitation amounts of five heavy metal elements Pb,Cr,Ni,Cd and As of these stainless steel cups were analyzed by using an atomic absorption spectrophotometer.The relationship between the precipitation of the heavy metals and the material elements in the stainless steel cups was studied.The material content of Ni had significant impact on the precipitation amounts of the heavy metal Pb.The material contents of C,Si,Mn and P had significant impact on the precipitation amounts of heavy metal Cr.The material contents of C,S,Mn,Cr and Ni had significant impact on the precipitation amounts of the heavy metal Ni.The material contents of Si,Mn,P,Cr and Ni had significant impact on the precipitation amounts of the heavy metal As.
