Embodiment 1

[0050] see figure 1 Shown, a kind of preparation method of bovine bone activated carbon, the steps are as follows:

[0051] ①Beef bone pretreatment

[0052] Use a scalpel to remove the remaining meat and other substances on the beef bone, use a hacksaw to cut the beef bone into a piece of beef bone with a length of about 5cm, remove the internal bone marrow, rinse it with running water, and then put it in an oven with a temperature of 105°C. Dry at constant temperature for 12h.

[0053] ② Coarse crushing of beef bones

[0054] The pretreated bovine bone is hammered repeatedly with a hammer until the bovine bone fragments are about 0.5cm-1cm in particle diameter.

[0055] ③ Degreasing of beef bones

[0056] Coarsely crushed beef bone fragments are packed in a triangular bottle, added with an appropriate amount of water, wrapped and placed in a high-pressure steam sterilizer for repeated cooking to degrease until no grease floats on the surface of the water. The degreased b...

Abstract

The invention discloses a preparation method and application of bovine bone activated carbon, and relates to the technical field of comprehensive utilization of domestic wastes and preparation of organic pollutant adsorbents. In the method, zinc chloride, potassium hydroxide and phosphoric acid are respectively used as activators, and bovine bone carbonized substance is activated to prepare the bovine bone activated carbon. Experiments show that when the bovine bone is carbonized for 2 hours at 400 DEG C, zinc chloride is used as an activating agent, and the bovine bone carbonized substance isactivated for 90 minutes at 400 DEG C, so that the adsorption effect of the prepared bovine bone activated carbon on methylene blue is the best; according to the method, 0.3 g of activated carbon prepared from zinc chloride is added into 100 mL of 100 mg / L methylene blue solution, and the removal rate reaches 100% after 4.5 h. In addition, through determination, comparison and analysis of surfacefunctional groups of the bovine bone activated carbon, the methylene blue adsorption capacity of the bovine bone activated carbon is not only related to pores of the bovine bone activated carbon, butalso related to surface functional groups of the bovine bone activated carbon.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of domestic waste and preparation of organic pollutant adsorbents, in particular to a preparation method and application of bovine bone activated carbon. Background technique [0002] my country is a country with a large population, and it eats and consumes a lot of meat every year. According to relevant data, in 2015, my country consumed about 9x10 pork, beef and mutton meat. 7 tons, of which about 85x10 4 tons, accounting for about 1 / 4 of the world's total. There are also many kinds of bones produced. How to rationally utilize these edible bovine bones is a problem worthy of our discussion and research. From the current point of view, the utilization of bone resources in my country has not yet been developed on a large scale. How to recycle bones, increase the value of by-products of livestock and poultry meat, and reduce environmental pollution and resource loss is a problem...
