Abstract
The present invention provides the preparation and application of a nanoporous carbon-calcium composite material for fast and efficient removal of organic pollutants. The preparation method comprises the following steps: (1) washing and drying the crustacean waste for later use; (2) The result of step (1) is placed in a muffle furnace, and under the condition of cutting off oxygen, it is pyrolyzed at 300-900°C for 0.5-3 hours to obtain final product; the nanoporous carbon-calcium composite material obtained in the present invention is resistant to various organic pollution The material has very excellent adsorption effect, short action time, and the highest adsorption capacity can reach 20317 mg / g; the nanoporous carbon-calcium composite material obtained in the present invention has a simple preparation process, and the raw materials are easy to obtain and cheap, and have very broad market application prospects.
Description
technical field [0001] The invention relates to the preparation and application of a nanoporous carbon-calcium composite material for quickly and efficiently removing organic pollutants, and belongs to the fields of adsorption material technology and resource utilization of waste biomass. Background technique [0002] The development of chemical companies has brought a lot of convenience to our lives, but the discharge of sewage has also been a controversial topic in recent years. Among the discharged sewage, the proportion of organic pollution remains high. These pollutants are mainly toxic and refractory organic substances, which are easy to cause cancer and deformity, directly endanger human health, and seriously damage water bodies, soil and ecological environment. With the continuous deepening of the concept of environmental protection, researchers have conducted long-term and in-depth research on this. [0003] In recent years, with the increase in the demand for shri...
