Without acid leaked and corrosion, it is easy to recycle and no pollution.
无漏液、漏酸、无腐蚀，回收方便，不污染环境。

At the same time, by taking acid testing, work curve scope testing, co-exist elements effect, recycle test, a fast analysis method for molybdenum in steel has been established.
同时，通过酸度试验、工作曲线线性范围测定、共存元素影响、回收试验等，建立了钢中钼的快速分析方法。
