Title:
WATER SAMPLE HARDNESS DETECTION METHOD BASED ON WATER SAMPLE ELECTRICAL SIGNAL CHANGE
Document Type and Number:
WIPO Patent Application WO/2023/010802
Kind Code:
A1
Abstract:
A water sample hardness detection method based on a water sample electrical signal change, comprising the following steps: S1: constructing a mathematical model related to water body hardness and a water body electrical signal change value; S2: enabling a water sample to be in contact with a calcium magnesium ion adsorption material to change an water sample electrical signal value, the calcium magnesium ion adsorption material being used for physically adsorbing calcium ions and magnesium ions in the water sample, acquiring water sample electrical signal values before and after the water sample is in contact with the calcium magnesium ion adsorption material, and then constructing a water sample electrical signal change value; and S3: substituting the water sample electrical signal change value into the water body electrical signal change value in the mathematical model, and calculating the hardness of the water sample. The method does not need to involve the use of a titration agent and a pre-calibration operation, and has low requirements for a hardware device, so that complex instrument daily maintenance can be avoided, and the method has the advantages of simple operation, high reliability and environmental protection.
