Reagent for determining sodium chloride content in urine, test paper strip thereof, preparation method thereof and purpose thereof

Abstract

The invention belongs to the field of analytical chemistry and particularly relates to a reagent for determining sodium chloride content in urine, a test paper strip thereof, a preparation method thereof and a purpose thereof. The reagent is composed of a reagent A and a reagent B; the reagent A is composed of 1-60 weight parts of silver nitrate and 1 volume part of water; the reagent B contains 0.5-20 weight parts of 2,7-dichlorofluorescein and 1 volume part of organic solvent selected from at least one of alcohol, phenol, ether, acid, amide and ketone of C1-C10. The reagent B further contains 0.5-50 weight parts of surface active agents and 1-70 weight parts of sulfosalicylic acid, and the relation between the weight part and the volume part is g / L. The test paper strip for determining sodium chloride content in urine is simple and convenient to operate, low in cost, favorable for industrial production and capable of quickly and conveniently determining sodium chloride content in urine, and thus can judge whether the salt intake is excessive.

Description

technical field [0001] The invention belongs to the field of analytical chemistry, and in particular relates to a reagent used for the determination of sodium chloride content in urine, a detection test strip, a preparation method and an application thereof. Background technique [0002] Adequate salt intake is an important prerequisite for ensuring health. Excessive salt intake can cause diseases such as hypertension, cardiovascular and cerebrovascular diseases, gastric cancer, edema, congestive heart failure, Meniere's disease, glaucoma, left ventricular hypertrophy, and diabetic nephropathy, which seriously threatens human health. [0003] The normal human body can maintain the stability of blood sodium in the blood. When the intake of salt is excessive, the human body excretes the excess salt through urine. Therefore, measuring the sodium content in the blood cannot detect whether the intake of salt is excessive. The easiest way to measure salt intake is to measure the ...

AI Technical Summary

Problems solved by technology

However, the 24-hour urine sodium ion determination and 24-hour urine chloride ion determination methods are complicated, require instruments, complicated operation, require operators to have certain professional skills, high cost, inconvenient to use, and are not suitable for home testing; However, the preparation process of the chemical chromogenic method test strip has a great influence on the performance, quality, effect and stability of the product, and the one-time immersion production method affects the stability of the product, which is not conducive to industrial production.
