Rapid aquaculture water ammonia nitrogen detection kit

Abstract

The invention discloses a rapid aquaculture water ammonia nitrogen detection kit which comprises ammonia nitrogen testing agents I, ammonia nitrogen testing agents II, a color comparison bottle and a color comparison card. The testing agents comprise p-aminobenzene sulfonic acid, N-ethylenediamine dihydrochloride, acids, surface active agents, stabilizers and distilled water. The kit has the advantages that the kit is rapid, sensitive, convenient and rapid to use, stable in quality and the like, the kit solves the problems that a conventional detection kit is complex in operation step in the detection process or the agents go bad and changes colors as the agents are placed for a long time and the like, the kit is simple and efficient in operating step and applicable to rapid on-site detection of various water without adding any devices.

Description

technical field [0001] The invention belongs to the field of water body detection, and in particular relates to a rapid detection kit for ammonia nitrogen in aquaculture water. Background technique [0002] The ammonia nitrogen content in the aquaculture water body is an important indicator of water quality detection in the aquaculture process. The ammonia nitrogen (NH 3 -N) is mainly free ammonia (NH 3 ) or ammonium salt (NH 4 + ) form; the ammonia nitrogen in the water body is mainly produced by the excrement of farmed animals decomposed by microorganisms in the water body, organic fertilizers in the water body, residual bait, etc.; the denitrifying bacteria in the water body can also Nitrite can be decomposed into ammonia nitrogen through denitrification. If the ammonia nitrogen content in the water body is too high, it will cause damage to the tissues of the farmed animals and reduce the transport of oxygen between the tissues; it will increase the permeability of th...

AI Technical Summary

Problems solved by technology

If the content of ammonia nitrogen in the water body is too high, it will cause damage to the body tissues of farmed animals and reduce the transport of oxygen between tissues; it will increase the permeability of fish gills, which is not conducive to its normal substance exchange with the outside world; it will affect the health of farmed organisms Feeding efficiency leads to slow production, decreased immunity and easy to get sick, which will lead to the continuous accumulation of toxic substances in the water, directly endangering the growth and survival of farmed animals, and will cause poisoning death in severe cases

[0003] In the process of detecting water samples, the existing ammonia nitrogen detection kits on the market sometimes react with the reagents due to excessive metal ions such as calcium ions, magnesium ions, iron ions, and manganese ions in the water samples to form white precipitates or turbidity. , so that the color cannot be developed; it seriously affects the detection of ammonia nitrogen content in water

Commonly used surfactants such as potassium sodium tartrate that are used to mask these metal ions cannot completely and completely mask the metal ions in water samples due to various reasons such as quality; or the quality of chemical reagents due to the impurity of mercuric chloride reagent Changes, which affect the color observation during the ammonia nitrogen detection process
