Abstract

The invention discloses a breeding water body total hardness detection kit, which contains a total hardness test reagent I, a total hardness test reagent II, two bottles of total hardness test reagentIII and a colorimetric bottle, wherein the test reagents I, II and III comprise disodium ethylenediaminetetraacetate, eriochrome black T, ammonium chloride, ammonia water, a synergist, a masking agent, absolute ethanol and distilled water. According to the present invention, the kit has advantages of rapidness, sensitivity, convenient use, obvious reaction, stable quality and the like, can overcome the problems of reagent deterioration, reagent color changing and the like of the common kit during the detection due to the complex operation steps or the long placing time, further has advantagesof simple and efficient operation steps, significant color change reaction and no requirement of the additional equipment, and is suitable for the on-site rapid detection of a variety of water qualities.

Description

technical field [0001] The invention belongs to the field of water body detection, and in particular relates to a rapid detection kit for total hardness of aquaculture water body. Background technique [0002] In the process of aquaculture, suitable water hardness is a necessary condition for maintaining the healthy growth of aquatic animals and plants. Therefore, the total hardness content in the aquaculture water body is an important indicator of water quality detection in the aquaculture process, and the hardness of the aquaculture water body should be detected at all times during the aquaculture process. The traditional hardness test method is the chrome black T method, which is cumbersome and complicated to operate; the current relevant patents are for hardness test in industrial water, the reagent configuration steps are complicated, and the test results need to be obtained by formula conversion or comparison with color comparison cards , the patent CN 104267144 A rel...
