Polyaluminum chloride (PAC) - Determination of pH

Abstract: 聚合氯化铝（PAC）的pH值测定可以通过两种方法进行：pH试纸法和pH计法。在pH试纸法中，取一定量的PAC样品，在室温下搅拌均匀后，用pH试纸蘸取样品，并通过比对色卡确定pH值。在pH计法中，取样品同样在室温下搅拌均匀，然后将电极插入样品中，用pH计读取pH值。为确保测定的准确性，应确保样品充分混合，并建议进行多次测定以取平均值，从而减少误差。

The pH value of polyaluminum chloride (PAC) can be determined by the following two methods:

  1. pH test paper method: Take out a certain amount of PAC sample, stir evenly at room temperature, dip a small amount of sample with pH test paper, compare the test paper to the Color Chart to determine the pH value of the sample.

  2. pH meter method: Take out a certain amount of PAC sample, stir evenly at room temperature, insert the electrode into the sample, and use the pH meter to read the pH value of the sample.

NBCHAO reminds you: when measuring pH, the sample should be fully stirred so that the sample can be fully mixed. In addition, in order to reduce errors, it is recommended to perform multiple measurements and take the average value.
