Problems solved by technology

[0006] Aiming at the shortcomings of traditional common soap and friction soap that are difficult to effectively clean heavy metals in the skin polluted by fine particles in the mining and metallurgy environment, the present invention uses heat-treated spores to specifically adsorb heavy metals on the skin surface on the basis of a large number of studies and experiments. Activated carbon immobilizes the dry powder of spores. After the spores specifically adsorb heavy metals, the heavy metals can be fixed with the help of the huge specific surface area of ​​the activated carbon, and the adsorption capacity is larger; at the same time, the activated carbon powder itself also helps to increase the friction of the cleaning soap, which can Effective cleaning of heavy metals in the surface and texture of the skin, avoiding or reducing the health hazards of heavy metals to mining and metallurgy workers

Embodiment 1

[0032] The preparation of embodiment 1 Bacillus pumilus activated carbon immobilized spore dry powder

[0033] The preparation of bacillus pumilus pumilus gac-immobilized spore dry powder comprises the following steps:

[0034] (1) Acquisition of spores: Take the activated Bacillus pumilus and add it to the sterilized beef extract liquid medium, and culture it with shaking at 32°C and 150rpm for 24 hours. When the cell growth reaches a stable period, raise the culture temperature to 60°C and continue to cultivate After 5h, centrifuge at 11000rpm for 10min to collect the precipitate, resuspend in sterile water and wash 3 times to obtain the spores; activation of Bacillus pumilus: take the freeze-dried powder of the strain and dissolve it in sterile normal saline, take 1 The ring was streaked on the solid medium containing 10% beef extract, and cultivated in a 30°C incubator for 24h to obtain activated Bacillus pumilus;

[0035] (2) Preparation of dry spore powder: sterilize th...

Embodiment 2

[0037] Example 2 Spore-Based Heavy Metal Cleansing Soap

[0038] The heavy metal cleansing soap based on spores comprises the following preparation raw materials and their mass percentages: plant soap base 90%, glycerin 3%, activated carbon immobilized spore dry powder 2% obtained in Example 1, sterile water 5%.

[0039] The preparation method of the heavy metal cleansing soap based on spores comprises the steps of: taking plant soap base, glycerin, activated carbon immobilized spore dry powder and sterile water according to the formula, dissolving completely at 55°C and stirring evenly, then importing mold at 25°C Down solidification molding, obtain the heavy metal cleansing soap based on spore.

Embodiment 3

[0049] The cleaning effect of cleaning soap of embodiment 3 tungsten mine mining plant dust

[0050] The dust in the open-air operation area was sampled in a tungsten mine factory in Jiangxi, and the cleaning effect of heavy metal cleansing soap based on spores was analyzed after the dust polluted the skin. For the content of heavy metals, refer to the relevant methods of "Determination of Copper, Zinc, Lead and Cadmium in Water Quality by Atomic Absorption Spectrophotometry" (GB7475-1987).

[0051] The experimental steps are as follows:

[0052] (1) Dust pollution: take 10×10cm pig back skin as the simulated skin, and evenly apply a layer of dust with a weight of 0.1g on it. Make multiple pieces and leave it for 2 hours to form dust and pollute the skin.

[0053] (2) Soap making: Prepare heavy metal cleansing soap, soap base soap, active carbon soap, unimmobilized spore dry powder soap respectively according to embodiment 2, comparative example 1-3.

[0054] (3) Cleaning o...

Abstract

The invention provides a spore-based heavy metal cleaning soap. The spore-based heavy metal cleaning soap is prepared from the following raw materials by mass percentage: 89-91% of plant soap base, 2.5-4% of glycerin, 1-3% of activated carbon immobilized spore dry powder and 4-6% of water. The invention belongs to the technical field of daily chemical products, and provides the spore-based heavy metal cleaning soap, which can be used for effectively cleaning heavy metals on the skin surface and in textures, so that the harm of heavy metals to the health of mining and metallurgy workers is avoided or reduced.

Description

technical field [0001] The invention belongs to the technical field of daily chemical products, and in particular relates to a spore-based heavy metal cleaning soap and a preparation method thereof. Background technique [0002] In traditional mining and smelting links, the process design is extensive, the production environment is harsh, and there are environmental pollution and many safety hazards. For example: toxic and harmful gun smoke produced by mining and blasting operations, mine dust and flue gas discharged from smelting furnaces, dust removal dust from the dressing and smelting industry containing a large amount of heavy metals and residual chemicals, etc. These fine particles formed in the special working environment of mining and metallurgy fall and deposit everywhere in the mining area and smelting plant, which is extremely easy to contaminate the skin and other exposed parts of the body. The difference between these fine particles and ordinary dust is that it...
