我们分别用燃烧水解法和碱熔法测定了26份煤氟含量,发现两法所测结果有很大差异,但仍存在显著相关性;进而从精密度、回收率、试验效率等方面将两者进行比较,体会到燃烧水解法在测定煤等矿物质氟含量时较为适宜。 We determined the content of fluorine in 26 coal samples by combustion and alkali fusion respectively and found that there are significant differences between the two methods. However, there are still significant correlations between the two methods. Furthermore, from the aspects of precision, recovery rate and test efficiency, Who were compared to experience the hydrolysis of coal in the determination of fluorine content of minerals such as more appropriate.
