The Resistivity Test of Three Edible Salt Solutions is Studied
The characteristics of the soil in the southeast coastal area of Zhejiang province is affected by the salt content of soil layer. In this paper, the resistivity of the solution of 3 kinds of edible salt mixed with pure water is studied. The test results show that the resistivity of the solution with the same ion concentration is independent of the water pressure, so the resistivity of the solution can be obtained through the mean value of different depth resistivity. There is a good correlation between the sodium ion content and the resistivity, and the total ion content is the same, but the correlation between the total ion concentration and the resistivity is better than the sodium ion, especially when the ion concentration of the mixed solution is less than 4 g/L. And the effect of the sodium ion on resistivity is more significant than other ions, but when the total ion concentration reaches 4g/L, the sensitivity of the resistivity affected by the sodium ion is reduced.
