Title:
METHOD FOR QUANTITATIVELY ANALYZING RESIDUAL CL IN ZINC FERRITE
Document Type and Number:
WIPO Patent Application WO/2019/035563
Kind Code:
A1
Abstract:
The present invention relates to a method for quantitatively analyzing Cl, remaining after synthesis, in zinc ferrite synthesized using chloride precursors such as zinc chloride and iron chloride, and provides a method capable of using, in a quantitative analysis method of Cl remaining after synthesis of an inorganic material, AQF-IC, which has been used only in the quantitative analysis of an organic sample since gaseous Cl, discharged after burning zinc ferrite in an automatic quick furnace (AQF) by using an Sn capsule and tungsten oxide (WO3), is analyzed through ion chromatography (IC).
