Abstract
The invention discloses a water total hardness test solution for aquaculture and aquarium as well as a preparation method and a use method of the test solution. Every 1,000 ml of the test solution contains 3.13-6.25 g of ethylenediamine tetraacetic acid (EDTA), 15-30 g of ammonium chloride (NH4Cl), 100-200 ml of strong ammonia water with the mass percent concentration of 25%-28%, 1-4 g of chrome black T and the balance of pure water. The reagent is easy to prepare, convenient to use and relatively small in measurement error, can be used for determining the hardness of a water body without a formula or a colorimetric plate, and is suitable for aquaculture and aquarium industries.
Description
Technical field
The present invention relates to a kind of water hardness test fluid, especially a kind of aquaculture and the Shui nationality total hardness of water test fluid and preparation method thereof and using method.
Background technology
The source of aquatic livestock and Shui nationality animal and plant very extensive, especially the original producton location water body hardness of the latter is different.For a lot of animals and plants, suitable water body hardness is the necessary condition maintaining its healthy growth.Thus, in the breeding process of the especially high-grade Shui nationality animal and plant of part aquatic livestock and most Shui nationality animal and plant, the hardness of breeding water body to often be detected.
The drawbacks such as traditional hardness detection method is eriochrome black T method, and this method exists operating personnel's technical requirement higher in implementation process, and testing procedure is too complicated, and test result needs to carry out formula scales, and medicine is not portable.There is no the Patents specially for aquaculture and aquatic animal cultivating field at present, Patents spininess, for process water, relates to drug variety more, and configuration step is more complicated, and test result still needs by formula scales, or need just can obtain compared with colour table.Aquaculture and Shui nationality industry all will be tested a large amount of water samples and various water-quality guideline every day, for the requirement of testing efficiency higher than the requirement to degree of accuracy, in other words aquaculture and Shui nationality industry are can obtain result intuitively fast and comparatively accurately to the requirement that water body total hardness is tested, simple and effective measuring method and test fluid contribute to raising labour efficiency, and save production cost.
Summary of the invention
The object of this invention is to provide a kind of fast and compared with the test fluid and preparation method thereof of Accurate Determining aquaculture and Shui nationality total hardness of water and using method.

4cl15.5g, mass percent concentration is the strong aqua 100ml of 25% ~ 28%, eriochrome black T 1g, and surplus materials is pure water.
The preparation method of above-mentioned aquatic products and aquatic animal cultivating total hardness of water test fluid, comprises the following steps:
(1) 15 ~ 30gNH is taken
4cl and 100 ~ 200ml strong aqua pure water are assigned to 500ml;
(2) 3.13 ~ 6.25g edta edta is taken;
(3) NH that the edta edta (2) taken configures with (1)
3-NH
4cl solubilize;
(4) take 1 ~ 4g eriochrome black T, add the solution of configuration in (3), pure water is settled to 1000ml.
The using method of above-mentioned aquatic products and aquatic animal cultivating total hardness of water test fluid, by changing the concentration of edta edta in test fluid or changing volume of water sample to be measured, the hardness number of the every 0.1ml representative of adjustment test fluid, according to the Dosage calculation water body total hardness of test fluid.
The present invention has the following advantages compared with existing correlation technique:
1, drug formulation composition is few, and preparing process is simple, facilitates factorial praluction.
2, easy to use, carrying out without the need to using formula calculating or checking colors with color board, can result be obtained.
3, the requirement to different precision can be met within the specific limits.
