In view of the defects in the method for measuring the concentration of ammonium perchlorate AP solution in the past, professionals such as Wang Wanyuan established a method for quickly measuring the concentration of AP solution with a density meter and a thermometer. Ammonium Acid Solution Concentration" introduced the specific process of the test in detail. The relationship table between temperature-density-concentration was obtained through experiments, as follows:

Use density meter and thermometer to quickly measure the concentration of ammonium perchlorate solution with Figure 1

Through this table, the mass concentration of AP can be quickly determined with a density meter and a thermometer.

in conclusion

①Using a density meter and a thermometer to measure the mass concentration of the AP solution has a small deviation (deviation <±4g/L), which meets the process requirements.

②The speed of measuring the mass concentration of AP solution is fast, only needing 1min, which improves the work efficiency.

③ No chemical reagents are used, no pollution to the environment, which is beneficial to the health of the staff and reduces the cost.

④The operation is simple, which can reduce the labor intensity of workers.
