摘要
[目的]pH值是农药检测中的一项重要理化性能指标。讨论了农药pH值测定时蒸馏水的pH值、仪器、温度等因素对测定值的影响。[结果]不同pH值的蒸馏水对农药pH值测定是主要的影响因素,而不同的仪器、温度等对农药pH值测定则基本没影响。[结论]提出了农药pH值测定时对蒸馏水的要求和测定时的注意事项。
[Aims] The pH value is an important physicochemical property of pesticides detection. The influence of the pH value of distilled water, instruments, and temperature on determination of pH value of pesticides was discussed. [Results] The influence of the pH value of distilled water is primary, while different instruments and temperature basically have nothing to do with the results. [Conclusions] The condition of distilled water and the notice when determination of pH value of pesticides were presented.
