中文摘要: 三氯化钛还原重铬酸钾滴定法测定低品位多金属矿石中全铁含量是一种常见的检测方法,其根据指示剂的颜色变化指示滴定终点,然后目测标准滴定溶液消耗的体积,计算分析结果。通过试样的测试,对分析结果精密度和准确度进行了考察,相对标准偏差RSD均小于1.000%,加标回收率为94.6～100.0%,可用于低品位多金属矿石中全铁含量在0.500%及以上的测定。
Abstract:Determination of total iron content in Low-grade polymetallic ore by titanium trichloride reduction potassium dichromate titration with is a common detection method,It indicates the end point of titration according to the color change of the indicator,and then visually measures the consumption of the standard titration solution.Volume, calculate the analysis results, Through the test of sample, the precision and accuracy of the analysis results were investigated.The relative standard deviation rsd was less than 1.000%,and the standard addition recovery was 94.6～100.0%,It can be used in low-grade polymetallic ore with total iron content at 0.500% and above measurements.
keywords: reduction of titanium trichloride potassium dichromate titration low grade polymetallic ore total iron content.
