摘要
样品经70%王水处理,除去碳酸盐、硫化物以及部分有机质等。在600℃下,处理后的样品使用总碳分析仪灼烧180 s,再经950℃灼烧,测定样品中固定碳的含量。该方法快速、简便、准确,适合对页岩中低含量固定碳的测定。
A method for the determination of fixed carbon in shales was reported.The sample was decomposed by aqua regia of 70% to remove the interferences from carbonates,sulfides,organisms.After calcined at 600 ℃ for 180 s and at 950 ℃,the fixed carbon was determined.The method is rapid,simple,accurate,and suitable for the determination of fixed carbon in shales.
