Embodiment 1

[0031] Embodiment 1, the preparation of porous hydroxyapatite

[0032] i) Take Tween-80 and add 100ml of toluene with a concentration of 0.5%. After shaking well, add 50ml of 1mol / L sodium carbonate solution, ultrasonic emulsification for 15min, and pour the emulsion into 300ml of 0.2mol / L calcium chloride solution. Stir and react for 2 hours, age for 24 hours, filter the aged solution with suction to obtain a white precipitate, wash with distilled water and absolute ethanol for 3 times, dry at 80°C for 12 hours, and obtain porous spherical calcium carbonate powder;

[0033] ii) Take the above-mentioned porous spherical calcium carbonate powder and add purified water to form a suspension of 0.05 g / ml. Under stirring conditions, add 0.03 mol / L disodium hydrogen phosphate solution to keep the pH at 11, stir for 12 hours, and age for 24 hours; filter the aged solution with suction to obtain a white precipitate, wash with distilled water and absolute ethanol three times, dry at 8...

Embodiment 2

[0034] Embodiment 2, preparation of anode furnace refining slag

[0035] S1. Sintering: take the copper-containing sludge and carry out sintering, move the sintered block into the smelting furnace, add limestone 10kg / t Cu, carbon fine 3kg / t Cu, and continuously feed in air containing 25% (v / v) oxygen at the same time Calcining to obtain blister copper, wherein the calcination temperature is 1100°C;

[0036] S2. Refining: move the above-mentioned blister copper into the refining furnace, add 3kg / t Cu heavy oil, and at the same time continue to feed air containing 95% (v / v) oxygen to mix the blister copper, add carbon powder 2kg / t Cu and 4kg / t Cu quartz stone to obtain anode copper plate and anode furnace refining slag, in which the calcining temperature is 1200°C.

[0037] The prepared anode furnace refining slag mainly includes the following components by weight: CaO 6.2-8.3wt%, SiO 2 25.6~29.2wt%, Al 2 o 3 6.3~9.4wt% and FeO 25.4~35.8wt%.

Abstract

The invention belongs to the technical field of deodorization and particularly relates to a deodorant used for removing a volatile stink of feces and a preparation method and application thereof. Thedeodorant is prepared from, by weight, 20-40% of porous hydroxyapatite powder, 30-65% of anode furnace refined slag and 6-22% of natural zeolite. The deodorant can obviously reduce the concentration of skatole, indole, ammonia gas, hydrogen sulfide, methane and other smelly gaseous substances, the cost is low, the deodorant can be reutilized, and a remarkable progress is achieved.

Description

technical field [0001] The invention belongs to the technical field of deodorization, and in particular relates to a deodorant for feces volatile odorous gas, a preparation method and application thereof. Background technique [0002] Feces are the excrement of the body, and are currently widely used in outpatient examinations, disease research, and the technology of fecal bacteria transplantation that has emerged this year. In outpatient testing, examiners assist clinicians in diagnosing diseases through fecal occult blood tests and parasite egg inspections; in disease research, conduct etiological research on diseases through fecal metabolomics and metagenomics technologies; In the laboratory preparation process, feces need to be used in large quantities. However, irritating volatile substances such as indole, skatole, ammonia, methane, hydrogen sulfide, acetic acid, butyric acid in feces often cause trouble to medical staff and researchers. Therefore, how to remove the ...
