【摘要】 采用邻啡罗啉分光光度法测定废砂浆中铁含量,探究了废砂浆中重金属铬对测定铁离子含量的影响。结果表明,废砂浆中铁含量测定值为2.61%,相对标准偏差为2.24%,平均回收率为98.92%。该方法对废砂浆中重金属铬的抗干扰性强,精密度及准确度高、快速、简便、成本低,是一种适用于废砂浆中铁含量测定的分析方法。更多还原

【Abstract】 The iron content in the waste slurry was determined by spectrophotometric method. Explored the influence of trace heavy metal chromium in waste slurry on the determination of iron content. The result showed that the iron content in the waste slurry was 2. 61%,the RSD was 2. 24%,and the average recovery was 98. 92%. This determination method has a strong anti-interference for Cr in the waste slurry,and is sensitive,accurate,rapid,simple,low-cost,which is suitable for the determination of iron content in the waste slurry.更多还原
