A rapid detection kit for nitrite in aquaculture water

Abstract

The invention discloses a rapid aquaculture water nitrite detection kit which comprises one bottle of testing agent, a color comparison bottle and a color comparison card. The testing agent comprises 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 nitrite in aquaculture water. Background technique [0002] In intensive aquaculture water bodies, the stocking density of aquatic animals is high, and the amount of bait fed is large. A large amount of nitrogen-containing organic matter such as residual bait, animal and plant excreta, and dead remains is easily accumulated in the aquaculture water body. In addition, untreated aquaculture Wastewater and industrial and domestic sewage are discharged or washed by rainwater into the aquaculture water body, resulting in a serious excess of nitrite in the aquaculture water body. [0003] Exceeding the standard of nitrite can easily lead to a large number of harmful bacteria and conditional pathogenic bacteria, and the physical fitness of fish, shrimp and other farmed animals will decline, and their anti-stress ability will be poor. cause huge ...

Problems solved by technology

[0002] In intensive aquaculture water bodies, the stocking density of aquatic animals is high, and the amount of bait fed is large. A large amount of nitrogen-containing organic matter such as residual bait, animal and plant excreta, and dead remains is easily accumulated in the aquaculture water body. In addition, untreated aquaculture Wastewater and industrial and domestic sewage are discharged or washed by rainwater into the aquaculture water body, resulting in serious excess of nitrite in the aquaculture water body

[0003] Excessive nitrite can easily lead to a large number of harmful bacteria and conditional pathogens, and the physical fitness of fish, shrimp and other farmed animals will decline, and their anti-stress ability will be poor. cause huge economic losses

[0004] Although the common water quality nitrite detection kits on the market are easy to operate and easy to carry, they have poor anti-interference ability, are prone to false positive and false negative results, and have low sensitivity.

And most of them are powder or a combination of various reagents. Farmers often encounter problems such as uncontrollable powder usage and deterioration of reagent quality during the detection process, which makes the detection results inaccurate; sometimes more detection reagents are used. It is cumbersome, and the test results are prone to large errors if you do not pay attention to it

Chinese patents CN 102507553A, CN 103743727A, and CN 104407097 are all kits for detecting nitrite content in aquaculture water. They are all mixed with ordinary chemical indicators. The former reagent has cumbersome operation steps and poor reagent stability. The color development time of the reagent is a bit long
