【摘要】：建立了KOH等度淋洗离子色谱法同时测定食品生产用水中氟化物、氯化物、亚硝酸盐、硝酸盐、硫酸盐5种阴离子的检验方法。结果表明:5种离子可在38min内检测完毕,各离子线性相关系数在0.9957~0.9999之间,检出限为0.002~0.006mg/L,回收率为97.27%~103.11%,能够满足食品生产用水这些指标的定量需求,是一种灵敏、准确、快速的理想方法。
[Abstract]:A method for the simultaneous determination of fluoride, chloride, nitrite and sulfate in food production water by KOH isometric elution ion chromatography was established. The results showed that the five ions could be detected in 38min, the linear correlation coefficients of each ion were between 0.9957 and 0.9999, the detection limit was 0.002mg / L, the recovery was 97.27% and 103.11%, the detection limit was 0.002mg / L, and the recovery was 97.27% and 103.11%, respectively. It is a sensitive, accurate, rapid and ideal method to meet the quantitative demand of water for food production.
