摘　　要：工业原料盐酸日用量大,为防止采购的工业盐酸混有氟离子超标的副产盐酸,而导致机械设备腐蚀和损坏的现象,需要增加原料盐酸的氟离子指标检测,新购HC-800 F pH全自动离子分析仪用于检测原料盐酸中的氟离子,并进行分析方法的建立。结果表明,在试验条件下,浓度与其相应响应值之间的线性相关系数为0.9997,标准偏差为0.16%,变异系数为0.19%,平均回收率为94.89%。该方法可以满足工业盐酸氟离子的测定,结果呈现性好。Due to the large daily consumption of industrial raw material hydrochloric acid,to prevent the purchase of industrial hydrochloric acid mixed with fluoride ions exceeding the standard by-product hydrochloric acid,resulting in corrosion and damage of mechanical equipment,it is necessary to increase the fluoride ion index detection of raw material hydrochloric acid,and the newly purchased HC-800 F pH automatic ion analyzer detects fluoride ions in raw material hydrochloric acid,and the establishment of analysis methods.The results showed that the linear correlation coefficient between the concentration and its corresponding response value was 0.9997,the standard deviation was 0.16%,the coefficient of variation was 0.19%,and the average recovery rate was 94.89%.which could meet the determination of industrial hydrochloride fluoride ion and the results were presentable.
