6种有机磷农药标准溶液不确定度分析

Uncertainty analyse of six organophosphorus pesticides standard solution

分析了乙酰甲胺磷、乙硫磷、丙线磷、苯硫磷、特丁磷、硫线磷6种有机磷农药标准溶液研制过程中测量不确定度的影响因素,并计算出有机磷标准溶液质量浓度的扩展不确定度。不确定度分量中,配制过程和溶液稳定性的不确定度是主要的。

The influence factors during the measument of uncertainty for the acephate, ethion, ethoprophos, EPN, terbufos, cadusafos 6 organophosphorus pesticides standard solution were analyzed. The expanding uncertainty of organophosphorus pesticides standard solution was calculated. The preparation process and stability of solution were the mainfactors which most affected uncertainty of measurement system.
