| titleOfInvention | Modified coconut shell biochar, preparation method thereof and method for adsorbing heavy metal |
| abstract | The invention relates to modified coconut shell biochar and a preparation method and application thereof. The modified coconut shell biochar is connected with a halogen-containing group, micropores are distributed on the surface of the coconut shell biochar, and the diameter of each micropore is 2-3 nm; the specific surface area of the coconut shell biochar is 1000-1300 m 2 (ii) in terms of/g. The preparation method of the modified coconut shell biochar comprises the steps of placing the coconut shell biochar in a halide solution with the mass concentration of 3-7%, soaking and stirring for 1-5 hours, and then washing and drying. The method for adsorbing heavy metal by using modified coconut shell biochar comprises the step of placing the modified coconut shell biochar with the particle size of 120-200 meshes into a mixture containing heavy metal at the temperature of 30-100 ℃. The weight ratio of the modified coconut shell biochar to the heavy metal is more than 20: 3. The modified coconut shell biochar prepared by the invention has high specific surface area, high pore volume and stronger adsorption capacity. |
