preparation example Construction

[0030] The present invention also provides a preparation method of calcium element detection test paper, comprising the steps of:

[0031] (1) Preparation of impregnation solution: 3.5g-4.5g buffer solution, 50g-100g surfactant, 2.5g-5.5g concealing agent, 0.1g-0.9g calcium indicator, 0.9g-1.5g ethylenediaminetetra Acetic acid was added to the volumetric flask, and the volume was adjusted to 1000ml;

[0032] Wherein, the buffer solution is prepared with sodium hydroxide, the surfactant is a combination of polyvinylpyrrolidone and polyethylene glycol, and the masking agent is a combination of sodium tartrate and 8-hydroxyquinoline;

[0033] (2) Soak the porous nanomaterial in the dipping solution, take it out after soaking for 20 minutes, and put it in an oven for drying, the temperature of the oven is 30-50°C.

[0034] Preferably, in the preparation method of the calcium element detection test paper of the present invention, the pH value of the soaking solution in step (1) is...

Embodiment 1

[0036] This example provides a method for preparing a test paper for detecting calcium deficiency in children's urine, comprising the following steps:

[0037] (1) Preparation of impregnation solution: 3g sodium hydroxide, 25g polyvinylpyrrolidone, 30g polyethylene glycol, 5.5g tartaric acid, 0.05g calcium indicator, 0.9g EDTA are added in the volumetric flask, and the volume is adjusted to 1000ml with distilled water;

[0038] (2) Making porous nanomaterials: Soak 1g of activated carbon with a specific surface area of ​​1200m2 / g and an average pore diameter of 2.5nm in concentrated nitric acid with a mass fraction of 70% and stir at 65°C for 2 hours, filter, wash with water, and dry for later use . Take 1g of acrylamide, add 50ml of distilled water, and heat at 45°C until completely dissolved. Then add 50ml of methanol and a small amount of ammonium persulfate in turn, stir evenly, pour into a container with activated carbon and stir for 10 hours at low temperature. Then, t...

Embodiment 2

[0042] This embodiment provides a method for preparing a test paper for detecting excess calcium in children's urine, comprising the following steps:

[0043] (1) Preparation of impregnation solution: 3g sodium hydroxide, 25g polyvinylpyrrolidone, 30g polyethylene glycol, 3g tartaric acid, 1.5g calcium indicator, 1.5gEDTA are added in the volumetric flask, and the volume is adjusted to 1000ml with distilled water;

[0044] (2) Making porous nanomaterials: soak 1g of activated carbon with a specific surface area of ​​1200m2 / g and an average pore diameter of 5nm in concentrated nitric acid with a mass fraction of 70% at 65°C for 2 hours, filter, wash and then dry for later use. Take 1g of acrylamide, add 50ml of distilled water, and heat at 45°C until completely dissolved. Then add 50ml of methanol and a small amount of ammonium persulfate in turn, stir evenly, pour into a container with activated carbon and stir for 10h at low temperature. Then, the container was reacted at a ...

Abstract

The invention disclose test paper for detecting trace elements. The test paper is spliced by routine urine test paper, test paper for detecting calcium elements, test paper for detecting iron elements and test paper for detecting zinc elements, and each color identification block corresponds to the detection result of each test paper. By the test paper for detecting the trace elements, whether the routine urine test items and content of trace elements such as the calcium elements, the iron elements and the zinc elements in the urine of a child are normal or not can be detected conveniently. A production method of the test paper for detecting the trace elements is simple and effective, and the disposable test paper is low in use cost, convenient to use and fast and accurate in detection result.

Description

technical field [0001] The invention relates to a trace element detection test paper and a preparation method thereof. Background technique [0002] During the growth and development of children, trace elements are a necessary requirement. The content of trace elements in the child's body can be inferred from the content of trace elements in the urine, and the nutritional status of the child can also be analyzed. [0003] At present, there is no comprehensive trace element detection test strip that can conveniently and comprehensively judge whether the contents of urine routine items and trace elements such as calcium, iron, and zinc in children's urine are normal. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a trace element detection test paper, which can conveniently and comprehensively judge whether the contents of routine urine items and calcium, iron, zinc and other trace elements in children's urine are ...
