酸溶除铁动物胶凝聚法测定铁矿石中的二氧化硅

Determination of silica in iron ore by acid soluble iron animal glue condensation method

试样经盐酸溶解,过滤分离铁离子,残渣经灰化、过氧化钠碱熔、动物胶凝聚重量法测定其质量分数,该方法消除了试样中大量铁离子的干扰,使测定结果更加稳定、可靠。

The sample was dissolved in hydrochloric acid,separating iron ion filtration, residue by condensation of ashing, Na2O2 alkali fusion, animal glue condensation method to determine the content, the method eliminates the interference of iron ion in the sample, the determination result is more stable and reliable.
