Description

Technical Field

[0002] Water is the source of life. Human beings cannot live without water in their daily life and production activities. The quality of drinking water is closely related to human health. Natural water contains a certain amount of sulfate ions. The content of sulfate ions will affect the quality of water. Too much content will make the water acidic and the water quality will decrease. Therefore, it is necessary to test the sulfate ion concentration in water.

[0003] The following method can be used to detect the sulfate ion concentration in water: first, hydrochloric acid is added to eliminate the interference of other ions, such as carbonate ions, silicate ions, sulfite ions, phosphate ions and silver ions; then, if no precipitation is produced, barium chloride solution can be added, and barium sulfate precipitation will be produced. The concentration of sulfate ions can be calculated by measuring the mass of the precipitate. However, after the solution reacts to produce a precipitate, the common test tube cannot quickly separate the precipitate from the solution, thereby affecting the progress of subsequent steps and greatly reducing the detection efficiency. In order to effectively and quickly separate the precipitate in the solution, the present application proposes a sulfate ion concentration detection device. Utility Model Content
