Abstract

The present invention relates to a preparation method and application of aquatic plant biochar-carbon nanotube composite material, comprising the following steps: mixing aquatic plant biochar and carbon nanotube suspension fully and stirring, drying and pyrolyzing to obtain the aquatic plant biochar-carbon nanotube composite material. Plant biochar-carbon nanotube composites. The carbon nanotube suspension is a suspension obtained by ultrasonication of carbon nanotube powder placed in deionized water; the aquatic plant biochar is fully mixed with the carbon nanotube suspension, dried, and then the aquatic plant is obtained under anaerobic high temperature conditions Biochar-carbon nanotube composites. The composite material prepared by this method can effectively adsorb and remove a large amount of Pb and Cu in the water body. The composite material prepared by this method can also be added to the soil where Pb and Cu exceed the standard, so as to reduce the bioavailability of Pb and Cu in the soil and play a role in preventing The purpose of controlling heavy metals.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a preparation method and application of an aquatic plant biochar-carbon nanotube composite material. Background technique [0002] With the rapid development of my country's economy, the demand for water resources is increasing, but at the same time, the pollution of water resources is also becoming more and more serious. Heavy metal pollution accounts for a considerable proportion of water pollution. Heavy metal pollution is easy to accumulate and expand in the biological chain, and is highly toxic. Therefore, excessive heavy metals in water and the problems caused by them have seriously endangered the ecological environment and human life and health. Among them, lead (Pb) pollution and copper (Cu) pollution in China are particularly serious. In recent years, there have been many incidents of lead pollution and copper pollution in my country. For example, ...
