矿物、岩石、原材料中H_2O~+的测定,通常有平菲尔特法和氯化钙吸收法.平菲尔特法尤其是对微量H_2O~+的测定,分析结果重现性不太理想,氯化钙吸收法虽然精确度高,但分析时间冗长,不适合快速分析要求.我们以五氧化二磷快速吸收直接测定石灰及其它岩石、矿物、原材料中的H_2O~+,效果很好,投产两年来证明,本法具有快速、准确、测定范围大等优点,完全可以代替氯化钙吸收法、平菲尔特法测定各种矿物、岩石、原材料中的H_2O~+.速度比平菲尔特法快两倍以上,分析步骤简单、操作方便.
The determination of H_2O ~ + in minerals, rocks and raw materials usually includes the flatfilt method and the calcium chloride absorption method.The Pingfelt method, especially for the determination of trace H_2O +, the analysis results are not very good in reproducibility, Calcium chloride absorption method has high accuracy, but the analysis time is too long, not suitable for rapid analysis requirements.We phosphorus dioxide rapid absorption of direct determination of lime and other rocks, minerals, raw materials H_2O ~ +, the effect is good, put into operation Two years to prove that this method has the advantages of fast, accurate, large measuring range, can replace the calcium chloride absorption method, flatfelt method for the determination of various minerals, rocks, raw materials H_2O ~ + speed than Ping Feier Special method more than twice faster, analysis steps are simple, easy to operate.
