摘要
水中的磷含量是评价水质的重要指标之一。采用钼锑抗分光光度法测定生活废水中的磷酸盐,根据不确定理论,估算出在实验过程中产生的不确定度分量,通过计算得到合成不确定度和扩展不确定度,为进一步降低测量不确定度,提高检测结果的准确性提供了依据。
Phosphorus is an important factor to evaluate the water quality.In this study,phosphates in domestic waste water were determined by molybdenum antimony spectrophotometric method.According to the uncertainty theory,the component of uncertainty produced in the experiment was estimated,the combined uncertainty and extended uncertainty are obtained by calculation.This study provides a basis for further reducing the uncertainty of measurement and improving the accuracy of detection results.
