Abstract
The invention relates to a testing agent for detecting ammonia nitrogen in water. The testing agent comprises A, B two packages, wherein the A is packaged by grinding and mixing sodium tartrate, natrium salicylicum, citric acid trisodium and nipride; the B is packaged by grinding and mixing sodium-hydroxide, lithium hydrate, citric acid trisodium, babysafe, symclosene and symclosene. When use the testing agent, adding a pack of A into sample water, adding a pack of B after placing 2 minutes, the water will display blue-green color if there's ammonia nitrogen in the water, and the darkness of the color is in proportion to the concentration of the ammonia nitrogen; placing 10 minutes, comparing it with the standard color matching card, color matching disc to read the concentration of the ammonia nitrogen in the water.
Description
[affiliated technical field]
The present invention relates to ammonia nitrogen concentration quick detection reagent and usage in a kind of water.
[background technology]
In the water pollution index, ammonia nitrogen is one of important test item, and the pollution surveys of the main water system of China in 2002 shows that ammonia nitrogen has all appearred in the main contamination index in the Changjiang river, the Zhujiang River, Haihe River, the Liaohe River, Taihu Lake, Dian Chi and Chaohu.The ammonia nitrogen of low concentration there is no direct harm to human body, and hydrobiont is not had much influences yet, when an amount of or nutriment, but if ammonia-nitrogen content is too high in the water body, then, all will produce harmful effect, sometimes or even catastrophic consequence to the water body quality not only to human body.Ammonia-nitrogen content is too high in the water body, can promote algae excessive propagation, reaches harmful degree until quantitatively, causes eutrophication, and water transparency is reduced, and water quality degenerates, so that have influence on the existence of fish, brings about great losses for the aquatic products aquaculture.Since the later stage nineties 20th century, the ammonia nitrogen in waters such as China Taihu Lake, Dian Chi, Chaohu is in eutrophication or heavy eutrophication state with regard to severe overweight.Nutrient pollutants such as excess of ammonia nitrogen not only cause body eutrophication, cause also simultaneously that nitrate and content of nitrite exceed standard in potable water, underground water and the crops, and nitrite also is a kind of generally acknowledged carcinogen.
The method of measuring ammonia nitrogen concentration in the water at present both at home and abroad mainly contains: salicylic acid spectrophotometric method, nessler reagent method, the chromatography of ions etc., salicylic acid spectrophotometric method and nessler reagent method major defect are that the operation steps complexity is loaded down with trivial details, analytical cycle is long, and the liquid reagent developing time is long and stabilization time short; The chromatography of ions rule needs expensive instrument.These methods all require high to operating personnel's professional skill, and can only finish in the laboratory, can not satisfy the requirement of fast-field evaluation.
[summary of the invention]
At existing method and the existing problem of reagent of measuring ammonia nitrogen concentration in the water, the objective of the invention is to propose a kind of easy operation, make things convenient for accumulating, the result is accurate, and is cheap, and is suitable for ammonia nitrogen quick detection reagent in the water of field quick detection.
The object of the present invention is achieved like this:
This reagent is divided into A, B bi-component package, and wherein the A component is even with the abundant ground and mixed of sodium tartrate, sodium salicylate, trisodium citrate and sodium nitroprussiate, is distributed into every bag 0.1 gram; The B component is even with NaOH, lithium hydroxide, trisodium citrate, sodium dichloro cyanurate, sym-closene, the abundant ground and mixed of sodium tartrate, is distributed into every bag 0.1 gram, is specially:
