| 摘 要： | 对测定室内空气中甲醛含量过程中甲醛储备液标定方法进行改进，用加入碘酸钾标准溶液的量和硫代硫酸钠溶液滴定所消耗的体积，直接计算出甲醛储备液浓度。与国标法比较，该方法简化了操作步骤，耗时短，且精确度高，可作为标定甲醛储备液的一种新方法。

| Abstract: | To improve the formaldehyde reserve liquid calibration method in the process of indoor air formaldehyde content detection, the amount of standard solution of potassium iodate and the consumed titration volume of sodium thiosulfate solution are added to calculate the concentration of formaldehyde in liquid reserves directly. Comparing to GB method, this method simplifies the operation steps, shorten the time consumed, and has a higher accuracy. This method can be used as a new solution of formaldehyde reserve liquid calibration method. |
