1. A hair care serum and a method for its preparation are disclosed, the composition of the hair care serum comprising: deionized water, olea europaea (olive) fruit oil, glycerin, polydimethylsiloxanol, Cetrimonium chloride, glyceryl stearate, cetearyl stearinol, DMDM glyceryl urea, and flavor. According to the hair care serum of the present invention, the olea europaea fruit oil is rich in unsaturated fatty acids and vitamin E, and is effective in shining hair, especially for the maintenance of hair toughness. The hair care serum also includes glycerin and polydimethylsiloxanol, the glycerin and polydimethylsiloxanol being effective in smoothing and moisturizing the hair. In addition, the hair care serum also includes cetrimonium chloride, which can be used to prevent static electricity and buildup in the hair, and cetrimonium chloride can combine water and stains to make it easier to rinse out, and thus can be used to clean the hair, eliminate odor and prevent microbial growth, thereby enhancing the hair care effect of the hair care serum.

2. A method of removing sulfur dioxide from flue gas is disclosed, using a process of generating 4.6-5.6 parts of ammonium hydroxide solution and 36.8-44.4 parts of Cetrimonium chloride solution, 3.0-6.9 parts of tetramethylammonium hydroxide pentahydrate, 35.5-41.0 parts of tetramethylammonium silicate solution, and 4.0-9.8 parts of fumed silica as a Reaction gel; then put into the hydrothermal reactor, add concentrated sulfuric acid, and then adjust the pH and continue the hydrothermal reaction 1-4 times, air-drying products for powder calcination to produce sulfur dioxide adsorbent, sulfur adsorbent loaded into the fluidized bed, fixed bed or moving bed, so that the flue gas and sulfur dioxide adsorbent full contact, control the contact pressure of 0.1-0.3MPa. The present invention has a high sulfur dioxide removal, sulfur adsorption capacity, suitable for 250% to 200% sulfur dioxide adsorption capacity. The invention has the advantages of high sulfur dioxide removal rate, large capacity of sulfur adsorption, suitable for use at high temperature of 250-800 ℃, especially suitable for metallurgy, electric power and other high-temperature environment of coal-fired flue gas treatment.


It is forbidden to mix with toxic and harmful substances. The product has certain moisture absorption. It should be stored in a sealed way in low temperature drycool and ventilated condition.
