Test paper for rapidly checking residual content of sterilizing agent

Abstract

The invention relates to a test paper for rapidly checking the residual content of a sterilizing agent, in particular to a prescription of a test paper for rapidly and sensitively checking the residual content of a sterilizing agent in an eye-measurement way and a preparation method thereof. The test paper for rapidly checking the residual content of a sterilizing agent is suitable for checking the important indexes such as residual uramine and chloride content which are used for grading the effect of water sterilization in medical sanitary units, public places, food eat trade, and the like on site. Uramine and chloride sterilizing agents are universally used at present and are also widely used in the sterilization of the tap water, the swimming pool, the tableware, and the like, thus, the test paper for rapidly checking the residual content of a sterilizing agent is very important for controlling and checking the content of residual uramine and chloride in water-supply processing.

Description

technical field [0001] The invention relates to a quick detection test paper for the residual disinfectant content, in particular to a formula and a preparation method of the fast, sensitive and visually detectable quick test paper for the residual disinfectant content. It is suitable for on-the-spot detection of important indicators for evaluating water disinfection effects in medical and health units, public places, catering and other industries - residual guanidine, residual guanidine, and chlorine content. Guanidine and chlorine disinfectants are widely used disinfectants at present, and are widely used in the disinfection of tap water, swimming pools and tableware. However, disinfectants containing guanidine and chlorine will produce a variety of by-products during disinfection, so the safety of chlorinated water quality has attracted increasing attention. The content of residual guanidine and chlorine is an important index to evaluate the disinfection effect of water. ...

Problems solved by technology

[0002] The object of the present invention is to provide a kind of fast, sensitive, visual inspection of disinfectant residual content quick test paper, the mensuration of residual chlorine and total chlorine in water, widely used in the past is o-toluidine method and iodometric method, these methods The operation is cumbersome and the analysis cycle is long (professional and technical personnel are required), which cannot meet the requirements of rapid and instant inspection of water quality, and is not suitable for on-site analysis; The residual chlorine detection method in the "Drinking Water Hygienic Standards" promulgated by the Ministry of Health in June 2001 has removed the o-toluidine method and replaced it with the p-phenylenediamine spectrophotometric method
