硅铁中铝和钙的联合测定

JOINTLY DETERMINING ALUMINIUM AND CALCIUM IN FeSi

为了快速准确地分析硅铁中的铝和钙的含量，介绍了用铬天青-S光度法测定铝含量，剩余母液用EDTA容量法测定钙含量的联合测定方法，可达到满意结果。

in order to rapidly and accurately analyze Al and Ca content in FeSi, itintroduces chromazurol-S photometric jointly determining method: determining Al content with chromazurol--S photometric method, determining Ca content in sulplus mother-liquor with EDTA volumetric method, and the result is satisfactory.
