摘要
详细叙述了采用EDTA络合滴定法滴定铁后 ,通过加苦杏仁酸掩蔽钛 ,用EDTA络合滴定法滴定铝而测得Al2O3 的含量 ,论证了用该法测定耐火材料中Al2O3 含量的精确性 ,确认了这种测定方法能准确、简便。
After determination of iron,titanium was sheltered by adding bitter almond acid,Al 2O 3 content in the sample could be got by titrating aluminium using EDTA chelatometry. The results of the tests confirmed that the method of the determination of Al 2O 3 content in common refractory was practical, accurate and easy to operate.
