Embodiment 1

[0034] Example 1: Preparation of Plant Salt Containing Sea Salt and Folium Folium Extract

[0035] Step 1. Preparation of refined brine

[0036] (1) Brine collection

[0037] Add potassium ferrocyanide to refined saturated brine with a pH value of 7 to prepare a 0.2 mg / L potassium ferrocyanide solution, then add sodium carbonate and calcium chloride, stir, stand still, and precipitate to remove Most of the Ca2+, Mg2+, and Fe2+ ions in the brine can be used to obtain relatively pure brine. In the brine, the detected molybdenum ion content is 10mg / L, the silver ion content is 10mg / L, and the cobalt ion content is 15mg / L.

[0038] (2) filter

[0039] Mechanical filtration: The collected brine is mechanically filtered to remove large solid impurities and mechanical impurities; the first layer is activated alumina as the filter material, and the second layer uses quartz sand as the filter material. The first filter material The specification of the first filter material is 2mm,...

[0064] Embodiment 2: Preparation of plant salt containing sea salt and Folium folium extract

[0065] Step 1. Preparation of refined brine

[0066] (1) Brine collection

[0067] Add potassium ferrocyanide to saturated brine with a pH value of 8 to prepare a potassium ferrocyanide solution with a concentration of 0.5 mg / L, then add sodium carbonate and calcium chloride, let stand, precipitate, and filter to remove the brine Most of the Ca2+, Mg2+, Fe2+ plasma in the medium can get relatively pure brine. In the brine, the molybdenum ion content was detected to be 15mg / L, the silver ion content was 15mg / L, and the cobalt ion content was 20mg / L.

[0068] (2) filter

[0069] Mechanical filtration: The collected brine is mechanically filtered to remove large solid impurities and mechanical impurities; the first layer is activated alumina as the filter material, and the second layer uses quartz sand as the filter material. The first filter material The specification of the first ...

Embodiment 3

[0093] Embodiment 3: the preparation of the plant salt containing sea salt and Folium folium extract

[0094] Step 1. Preparation of refined brine

[0095] (1) Brine collection

[0096] Add potassium ferrocyanide to refined saturated brine with a pH value of 9 to prepare a potassium ferrocyanide solution with a concentration of 0.8 mg / L, then add sodium carbonate and calcium chloride, let stand, precipitate, filter, and remove Most of the Ca2+, Mg2+, and Fe2+ ions in the brine can be used to obtain relatively pure brine. In the brine, the detected content of molybdenum ions is 20mg / L, the content of silver ions is 20mg / L, and the content of cobalt ions is 25mg / L.

[0097] (2) filter

[0098] Mechanical filtration: The collected brine is mechanically filtered to remove large solid impurities and mechanical impurities; for mechanical filtration, activated alumina is used as the filter material for the first time, and quartz sand is used as the filter material for the second l...

Abstract

The invention provides sea salt and folium isatidis extract containing plant salt. In the plant salt, the content of NaCl is 75%-85%, the content of isatan B is 0.5%-1.5%, the content of beta-sitosterol is 0.1%-0.5% and the content of palmitic acid is 0.6%-0.8%. The invention also provides a method for preparing the plant salt by using a heavy metal ion removal process through a nanofiber membrane. The method comprises the step of preparing refined brine; the step of preparing the refined brine includes the sub-step of removing heavy metal ions with the nanofiber membrane; the sub-step of removing heavy metal ions with the nanofiber membrane includes the step of preparing a PAN (Polyacrylonitrile) spinning solution, wherein the nanofiber membrane has 3-5 layers and the filtration pressure is controlled at 0.1-0.5 MPa. The sea salt and folium isatidis extract containing plant salt prepared by the invention does not cake after being placed for three years and has the obvious effect on promotion of wound healing.

Description

technical field [0001] The invention relates to the development and utilization technology of plant salt in plants, in particular to a plant salt containing sea salt and Folium folium extract and a method for preparing the plant salt by using a nanofiber membrane to remove heavy metal ions. Background technique [0002] For a long time, human beings have relied on sea salt, well salt, rock salt mining and other methods to produce table salt to meet their own needs. However, the salts that humans eat for a long time are basically inorganic substances, which can only meet the human body's own needs for inorganic salts, and it is difficult to meet the needs of humans for various functional foods due to the improvement of living standards, especially the current market salt is basically chlorine. Excessive Na+ intake has obvious negative effects on the blood pressure and blood lipids of the human body. At present, people have a deep understanding of this problem, and have produ...
