摘要
研究了采用1mol/L盐酸低温分解矿样,以二甲酚橙-锆减色法测定矿石中的氟,铝的干扰可在显色后放置一定时间予以消除,该法具有灵敏度高、重现性好、易掌握等特点。
Using 1 mol/L hydrochloric acid to decompose the sample, fluorine in the phosphorite was determined by Xylenol Orange-zirconium impair method. The disruption of Al could be eliminated after presenting the color and keeping a long time,The sensitivity the method is high ,reappearance is good.
