Problems solved by technology

The hydrogen-rich magnesium rod method and the electrolysis method require a heating device and an electrolysis device respectively, which are only suitable for household or fixed-point use, and are inconvenient to carry. The water produced cannot be stored for a long time, and can only be prepared and drunk immediately
Not only that, the above two methods generally increase the hardness of the water, which affects the taste and is not suitable for some people (such as: patients with kidney stones and gallstones)
The gas-liquid mixing method also has its own problems. Because pure water and mineral water generally need ozone sterilization before filling, and then fill and seal in the state of residual ozone, if hydrogen is introduced into the water before ozone sterilization, it will cause damage to the water. Most of the hydrogen overflows during sterilization and loses its reducing effect. If active hydrogen is introduced after ozone sterilization, it will be difficult to guarantee the antibacterial effect of the product, and its storability and safety will be problematic
In addition, the gas-liquid mixing method takes a long time to produce hydrogen-rich water, and the reduction activity of water is also low, because the solubility of hydrogen in water is very low, it is difficult to reach an effective concentration, and the reduction activity of non-new ecological hydrogen molecules is not high. The tourmaline cup uses tourmaline and germanium placed in the cup to react weakly with water to generate a small amount of hydrogen molecules to produce reducibility. The disadvantage is that the amount of hydrogen generated is small, and the reducibility of water is weak. It can reach about -100mV, and it cannot play a good role in removing harmful oxidative substances in the human body.

Embodiment 1

[0034] In this example, 60 g of ferric nitrate nonahydrate and 20 g of cerium nitrate hexahydrate were added to 5 L of water, and after stirring for 15 minutes, all the iron salts and cerium salts were dissolved. Clean a porous titanium rod with a length of 40 cm, a diameter of 50 mm, an average pore diameter of 1 μm, and a porosity of 35% with nitric acid with a volume concentration of 2%, and then immerse it in a mixed solution of iron salt and cerium salt. After ultrasonication for 30 minutes, take out Porous titanium rods were dried in a constant temperature oven at 120°C for 3 hours. Put the dried salt-containing porous titanium rod into a box-type heat treatment furnace, raise the temperature to 600°C at a rate of 5°C / min in an air atmosphere and keep it warm for 60min, wash it twice with secondary deionized water after cooling in the furnace, and then installed in a fixed bed reactor. Dissolve 65g of palladium acetate in 5L of glacial acetic acid and water with a volum...

Embodiment 2

[0037] In this example, the bacteriostatic catalytic reduction porous material in Example 1 was fixed in a PVC filter housing with an inner diameter of 63 mm to make a fixed bed processor. After hydrogen and secondary reverse osmosis water are sucked into a small self-priming pump at the same time, the gas and liquid are mixed through a small pipeline mixer, and then flow through a fixed bed processor equipped with a bacteriostatic catalytic reduction porous material to produce a bacteriostatic Sexual Kangen Water.

[0038] Under the conditions of water flow rate of 100L / h and hydrogen flow rate of 200mL / min, the concentration of silver ions in the effluent was not detected, and the oxidation-reduction potential was -630mV.

[0039] The above-mentioned reduced water was sealed in an aluminum foil bag. After 6 months, the redox potential was -615mV, and no Escherichia coli was detected in the water.

Embodiment 3

[0041] In this example, the bacteriostatic catalytic reduction porous material in Example 1 was fixed in a PVC filter housing with an inner diameter of 63 mm to make a fixed bed processor. After 100L of raw water is sterilized by ozone, the residual ozone concentration is 0.45mg / L. Ozone water circulates through the fixed-bed processor equipped with antibacterial and catalytic reduction porous materials at a flow rate of 200L / h, and at the same time, hydrogen gas is introduced at a flow rate of 500mL / min. After circulating for 2 hours, samples are taken for testing. The oxidation-reduction potential of the water sample was -645mV, and ozone and silver ions were not detected.

[0042] The above-mentioned reduced water was sealed in an aluminum foil bag. After 6 months, the redox potential was -625mV, and no Escherichia coli was detected in the water.

[0043] The results of the examples show that the bacteriostatic catalytic reduction porous material prepared by the method of ...

Abstract

The invention belongs to the technical field of new materials and relates to a bacteriostatic catalytic reduction porous material, its preparation method and its application in the production of reduced water. The porous material of the present invention is a carrier, metal iron, cerium and palladium are catalytic reduction active components, and nanosilver is an antibacterial component. The catalytic product is prepared by impregnation, calcination, in-situ catalytic reduction deposition, in-situ photoreduction deposition and other processes. Materials, palladium and silver are evenly dispersed and loaded on the pore walls and outer layer of the porous carrier in positions that are fully in contact with water vapor, maximizing the catalytic reduction effect while ensuring the antibacterial effect. The invention solves the contradiction between the antibacterial properties and reducing properties of reduced water, achieves antibacterial preservation under ordinary filling (compared to aseptic filling) conditions, simplifies the production process of reduced water, and reduces costs. Since the material and device work under strong reducing conditions, silver mainly exists in elemental form, which not only has low loss and long life, but also does not introduce excessive silver ions into the water, and is highly safe.

Description

technical field [0001] The invention belongs to the technical field of new materials, and relates to a bacteriostatic catalytic reduction porous material, a preparation method thereof and an application in producing reduced water. Background technique [0002] Water is the source of life, and the quality of water determines the quality of human life and plays a decisive role in human health. With the improvement of living standards, people pay more and more attention to healthy drinking water, and obtaining healthier water has become an urgent need. Since Professor Ohsawa of Japan discovered in 2007 that hydrogen can selectively scavenge malignant free radicals in the human body and produce antioxidant effects, the prevention and treatment of hydrogen-rich water on human chronic diseases has become a research hotspot. The role of hydrogen in diabetes, cardiovascular and cerebrovascular diseases , cancer prevention and treatment, and reports on beauty and anti-aging have eme...
