principle

The buffer solution needs to be stored at low temperature and away from light, with a pH controlled within the range of 9.6-11.5, otherwise the absorbance will be high. when

When the water sample contains volatile acids, it can lower the pH of the distillate. It should be added to the distillate to adjust it to neutral before adding

Buffer solution. Otherwise, when the pH is less than 9.8, certain compounds can interfere with the measurement of phenols by developing color with the color reagent

Ding. Color reagents are crucial for experimental accuracy, and national standards mention the purification of reagents. Therefore, what should be chosen

Reagents are important for experiments. Based on experimental experience, each reagent added during the color development process should be thoroughly mixed

Uniform. The control of color development time is essentially the control of the color development environment, controlling the water sample and standard curve environment

Thus obtaining the result.
