Method for ensuring content of carbonate ions to be controlled during calibration of sodium hydroxide standard solution

The invention discloses a method for ensuring the content of carbonate ions to be controlled during calibration of a sodium hydroxide standard solution. The method comprises the following steps of 1)carrying out calibration according to the provisions of 4.1.2 parts in GB/T 601-2016, carrying out an experiment by two persons in the calibration process, respectively carrying out four parallel operations by each person, carrying out titration by one person in a hand-cranking mixing manner, and carrying out titration by the other person in a magnetic stirring mixing manner, meanwhile, performinga blank test, and finally calculating the concentration of the sodium hydroxide standard titration solution, 2) calculating the concentration of the sodium hydroxide standard titration solution in the step 1), if the relative range is less than 0.18%, calculating the average value of all parallel experiments, enabling the obtained concentration to be the concentration of the sodium hydroxide standard titration solution, i
