Embodiment 1

[0018] A preparation method of waste chicken bone adsorbent, comprising the following steps: 1) take 1 kg of chicken waste produced by extracting chondroitin in the food processing industry, manually separate the chicken bone in the waste from the chicken and tissue remaining on the surface, and rinse with tap water for 3 2) Manually remove the bone marrow and other impurities in the chicken bones, rinse 2 times with tap water; 3) Add 1 liter of 5% sodium hydroxide lye to step 2, soak in 80°C hot water for 12 hours; 4) Put the Discard the lye in step 3, wash with tap water 3 times; 5) dry the chicken bones cleaned in step 4 in an oven at 105°C for 12 hours, grind them with a grinder, pass through a 200-mesh nylon sieve, and mix evenly to obtain the obtained required chicken bone adsorbent.

Embodiment 2

[0019] Embodiment 2: a kind of preparation method of waste chicken bone adsorbent, comprises the following steps: 1) take 0.5kg chicken skeleton, manually separate the chicken bone in the waste and the remaining chicken, tissue etc. on the surface, rinse 4 times with tap water; 2) Manually remove the bone marrow from the chicken bones, rinse with tap water 3 times; 3) add 0.8 liters of 2% sodium hydroxide solution to step 2, soak in hot water at 100°C for 12 hours; 4) discard the lye in step 3 , washed 4 times with tap water; 5) Dry the chicken bones cleaned in step 4 in an oven at 80° C. for 16 hours, grind them with a grinder, pass through a 200-mesh nylon sieve, and mix evenly to obtain the required chicken bone adsorbent.

Embodiment 3

[0020] Embodiment 3: a kind of preparation method of waste chicken bone adsorbent, comprises the following steps: 1) take 0.8kg chicken wing root, manually separate the chicken bone in the waste and the remaining chicken, tissue etc. on the surface, rinse 3 times with tap water; 2) Manually remove the bone marrow from the chicken bones, rinse with tap water 3 times; 3) add 1 liter of 10% sodium hydroxide solution to step 2, soak in hot water at 100°C for 12 hours; 4) discard the lye in step 3 , washed with tap water 4 times; 5) Dry the chicken bones cleaned in step 4 in an oven at 105° C. for 12 hours, grind them with a grinder, pass through a 200-mesh nylon sieve, and mix evenly to obtain the required chicken bone adsorbent.

[0021] The obtained adsorbent of embodiment 1 is carried out mineral property analysis (attachment figure 1 ). X-ray diffractometer (XRD) results show that the diffraction peaks match well with the mineral spectrum of hydroxyapatite, but the bottom of ...

Abstract

The invention belongs to the technical fields of solid waste resource recycling and heavy metal wastewater repair and in particular relates to a method for preparing a waste chicken bone adsorbent. The method mainly comprises the following steps: bone and meat separation, alkali soaking, drying and grinding, and the like. The prepared waste chicken bone adsorbent can achieve the heavy metal adsorption efficiency of 0.5-1.5mol / kg, and has high adsorption capacity; the preparative raw materials of the waste chicken bone adsorbent are wastes produced in the chicken processing procedures, and thepreparation method is simple, low in cost and low in investment; and the chicken bone adsorbent has high adsorption capacity on lead in the wastewater, the lead in the wastewater can be effectively removed, and the application environment is environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of solid waste recycling and heavy metal wastewater restoration, and in particular relates to a preparation method of a waste chicken bone adsorbent. Background technique: [0002] In the past two decades, the consumption and production of chicken in various countries in the world have shown a steady increase year by year. According to the United States Department of Agriculture, the global chicken consumption in 2016 was 87.64 million tons. China is the second largest chicken consumer. In 2016, my country's consumption was 12.72 million tons, accounting for 14.51% of the world's total. During the rough processing of chicken, various by-products (such as chicken skeleton, chicken scraps) are also increasing. These by-products are rich in minerals (hydroxyapatite), proteins, fatty acids, collagen, chondroitin and various vitamins. In addition, a large amount of waste containing minerals will also be produ...
