硫脲法测定铸铁中的磷在“理化检验通讯”67年第6期(58页)发表以后,陆续接到一些单位来信,索取硅、锰分析方法,并要求介绍磷的理论部分以及注意事项。因此,我们把硅、锰分析部分加以介绍,供参考。
Thiourea method for the determination of phosphorus in cast iron After the publication of the Journal of Physical and Chemical Testing 69 (6) (58 pages), I received a letter from some units to obtain silicon and manganese analysis methods and asked to introduce the theoretical part of phosphorus and Precautions. Therefore, we introduce the silicon and manganese analysis for reference.
