【摘要】 建立了傅立叶变换红外吸收光谱测定高、中、低浓度D2O的方法。该法具有快速、简便、样品无需处理即可直接测定的优点。方法精密度高,D2O浓度(摩尔分数)为99.84%时,标准偏差优于0.001;测量范围宽,D2O浓度检测范围为99.92%~0.015%;样品用量少,0.2 mL样品即可获得准确结果。更多还原

【Abstract】 A method to determine D2O concentration(mole fraction)of high,medium and low heavy water with Fourier infra-red spectrophotometer had been established.Its outstanding advantages were rapid,convenient,less sample(0.2 mL sample),high precision,and direct determination without pretreatment.For 99.84%,D2O concentration,the precision was better than 0.001.The determined range of D2O was 99.92%-0.015%.更多还原
