梯度－抑制电导离子色谱法测定粘土矿微生物浸出液中镁离子含量不确定度评定

摘要

Uncertainty sources of the calcium determination in clay bioleaching solution by ion chromatography were evaluated. Major factors and secondary factors influencing the calcium measurement were defined finally. The relative uncertainty and expanded uncertainty were calculated.%对梯度－抑制电导离子色谱法测定粘土矿微生物浸出液中镁离子含量不确定度来源进行评估，确定了测定过程中引入的不确定度的主、次影响因素，得到相对不确定度和扩展不确定度。
