Abstract

The invention discloses an on-site rapid detection method for iron ions in water capable of eliminating the influence of reagent blanks. The method prepares a liquid-type iron ion detection reagent, deducts the blank color of the reagent, and manufactures a standard color card with a transparent plastic plate as a supporting material. , Superimpose the color of the blank tube on the standard color card and compare it with the sample tube during detection, which has the advantages of simple method, high accuracy, and easy operation; using liquid iron ion detection reagent for detection can effectively control the entire detection process. It takes time; by superimposing the color of the blank tube on the standard color card and then comparing it with the sample tube for color comparison, it can effectively eliminate the adverse effects of reagent blank fluctuations on the accuracy of the test results, especially suitable for rapid on-site detection of iron ions in water .

Description

technical field

[0001] The invention belongs to the field of water quality detection, and in particular relates to an on-site rapid detection method for iron ions in water which can eliminate the influence of reagent blanks. Background technique

[0002] Iron (Fe) is an essential trace element for the human body. It has many physiological functions in the human body. In daily life, the human body absorbs trace elements through drinking water in a corresponding proportion. The detection of iron ion content is a detection item stipulated in the national drinking water standard.

[0003] The detection of iron ions in water mostly uses atomic absorption spectrophotometry, visible light spectrophotometry, inductively coupled plasma atomic emission spectrometry / mass spectrometry, electrochemical analysis, etc. Professional operators and technicians complete the test, most of the methods still need expensive large-scale special instruments, which cannot meet the requirements of fas...
