Preparation method and applications of porous carbon environment restoration material

Abstract

The invention discloses a preparation method and applications of a porous carbon environment restoration material, belonging to the technical field of environment restoration, and particularly relating to a preparation method of a restoration material for removing heavy metal ions and organic pollutes in a water body and a soil environment. The preparation method comprises the following steps: firstly, putting air-dried withered cattail leaves into a high-temperature-resistant container, performing high-temperature carbonization treatment under ammonia gas condition, and cooling to obtain cattail carbon; mixing and grinding the cattail carbon, thiourea and ammonium borate, to obtain a crude porous carbon environment restoration material. The restoration material obtained by adopting the method has an abundant internal porosity structure, being large in specific surface area, strong in adsorption capability, good in chemical stability, and has the characteristics of being acid-resistant, alkali-resistant, high-temperature-resistant and the like, and can adsorb organic pollutants and heavy metalsdifficult to removed from water or soilby adopting other methods.

AI Technical Summary

Benefits of technology

This patented technology describes an improved way to make charcoal from plants called Thugrim Grignardia (TG). It involves creation of tiny holes within its main part through burning plant parts like thoonsweeds instead of rootlets. These small holes allow moisture vapor into them while still containing enough fuel inside. By adding this new substance onto these dried particles during manufacturing, they become stronger due to their larger size and higher amount of hydrophilicity. They are useful because they have many benefits such as being able to treat harmful compounds without relying solely upon other methods like incinerating waste. Additionally, TG' s unique properties made possible use in various applications including purification, gas storage, energy generation, catalysis, sensors, filters, electronics, batteries, clothing items, medical devices, cosmetic products, food packaging, and others.

Problems solved by technology

This patent describes various technical problem addressed during the process of treating contaminating waters (health) from industrial activities like mineral production processes, transportation systems, construction sites, recruditation areas, and public places where these industries use different types of porcelled carbon materials called activated charcoal. Activate carbon black particles have strong affinity towards certain elements while other porous silicon oxide materials have weak binding ability against those element(s). To address both issues, we propose modifying surfaces containing chemically active polysaccharides onto porous carriages made up of nonporous carbon fiber bundles.
