高放废液和泥浆中F-,Cl-,NO2-,Br-,PO43-的测定
DETERMINATION OF F-,Cl-,NO2-,Br-,PO43-IONS IN HIGH-LEVEL LIQUID WASTE AND SLUDGE
【摘要】 使用Y2×8阳离子交换树脂柱除去高放废液和泥浆样品中可能存在的阳离子,采用硼酸 葡萄糖酸钠作淋洗液,改变了出峰顺序,降低了大量NO-3对测定的影响。本方法已成功应用于高放废液及泥浆中F-,Cl-,NO-2,Br-,PO3-4等阴离子的测定。4和SO2-
【Abstract】 The determination of anions F~-, Cl~-, NO~-2, Br~-, PO~3-)4and SO~2-)4 in high-level liquid waste (HLLW) and high-level radioactive sludge (HLRS) by ion chromatography(IC) is studied in detail. Potentially interfering cations are removed by pretreatment with a cation exchange resin column. A 10~4 times decrease in radioactivity is achieved by this step. Borate-gluconic acid solution is used as an eluent for IC to alter the peak sequence, and thus suppress the influence of NO~-3 ion. The method) has been successfully used for determination of various anions HLLW and HLRS.
