1) simultaneously extracted metals(SEM)
同步提取金属
1.
In this study,we measured the vertical distributions of the simultaneously extracted metals(SEM),including Cu,Cd,Ni,Pb,Zn and Fe,and acid volatile sulfide(AVS) in four anoxic sediment cores taken from the estuarine area of the Licun River in Jiaozhou Bay.
对胶州湾李村河口4个站点沉积物中的酸可挥发性硫化物(AVS)以及同步提取金属元素(SEM,包括Cu,Cd,Ni,Pb和Zn)的含量进行测定,以研究重金属元素在河口海湾沉积物中的分布特征及影响其分布的因素。
2) simultaneous extracted metals (SEM)
同步提取金属(SEM)
3) simultaneously extracted metal(SEM)
同步提取重金属(SEM)
4) simultaneously extracted metals
同步浸提金属
1.
The environments in landfill layer are analogous to that of marine sediments,so the ratio of AVS to simultaneously extracted metals(SEM) in landfill layer can be determinated referring to the analytical procedures of n(AVS)/n(SEM) in sediments.
填埋场环境与海洋底泥环境相似,因此可以参考沉积物中n(AVS)/n(同步浸提金属,SEM)的测定方法测定填埋层垃圾n(AVS)/n(SEM),发现n(AVS)/n(SEM)<5%。
2.
A method for analyzing AVS and simultaneously extracted metals (SEM( in landfills was developed and optimum conditions were discussed.
测定了填埋垃圾AVS的最佳反应条件,并在该条件下测定了杭州天子岭垃圾处理处置总场不同填埋深度垃圾的AVS与同步浸提金属(SEM),发现AVS随着填埋深度的增加而增加,但是n(SEM) n(AVS)远远大于1,为25～45,说明填埋场中AVS不是重金属的主要结合相,AVS不是影响填埋场中重金属迁移性的主要因素。
6) extraction of rare metal
贵金属提取
1.
The principle of liquid membrane technology and its application in pharmaceutical chemical engineering, extraction of rare metal, trace analysis and treatment of waste water are discussed in detail.
