【摘要】 用0.01 mol/L硝酸银溶液电位滴定,测定铁质文物除氯碱性浸泡液中的氯离子浓度。通过检测空白加标溶液,确定其检测下限为3.43 mg/L,定量限11.44 mg/L。跟踪检测模拟铁质文物除氯的浸泡碱液,其加标回收率为100.0%~100.7%。针对浓度介于检测限和定量限之间的样品,提出阶梯增量法,更加符合文物除氯工作的需要。更多还原

【Abstract】 Automatic potentionmetric titration using 0. 01 mol/L silver nitrate solution to determine the chloride ion solution. The LOD was 3. 43 mg/L and the LOQ was 11. 44 mg/L by detecting the blank spiking solution. The recoveries of the soaked alkali solution were simulated,and the recoveries were in the range of 100. 0% ~ 100. 7%. For the concentration between the detection limit and the limit between the sample,proposed step incremental method,more in line with the needs of deforestation work.更多还原
