| 摘 要： | 采用自制的高温水解装置处理样品,结合离子色谱法测定了再生锌原料中氟、氯的含量。试样在1 000℃高温下通入氧气与水蒸汽进行水解反应,以NaHCO_3(6.0mmol/L)与Na_2CO_3(2.4mmol/L)的混合溶液作为淋洗液,经SH-AG-1保护柱及SH-AC-3分离柱分离,测得F-在0~10 mg/L、Cl-在0~50mg/L范围内浓度与峰面积呈线性关系,相关系数分别为r=0.999 8和r=0.999 9,检出限分别为0.020mg/L与0.033 mg/L。分析再生锌原料中氟、氯的加标回收率分别在95.70%~102.5%和96.72%~101.3%,相对标准偏差(n=11)分别在2.1%~6.6%和2.0%~5.8%。方法对再生锌原料中氟(0.010%~1.00%)和氯(0.050%~5.00%)测定,结果满意。
