摘要
建立了离子色谱法同时测定石膏及石膏制品中氟和氯的方法。实验结果表明:采用离子色谱法一次进样可准确测定石膏及石膏制品中的氟和氯的含量。流动相采用20/30mM KOH溶液,流速为0.8/1.0mL/min。方法有较好的准确度和回收率。
Method to establish the ion chromatography method for the simultaneous determination of fluoride and chloride in gypsum and gypsum products.The experimental results show that： Using ion chromatography can be accurate determination of fluorine and chlorine in gypsum and gypsum products.The mobile phase is the 20/30mM KOH solution,the flow rate was 0.8/1.0mL/min. Method has better accuracy and recovery rate.
