| Abstract: | 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. |
