The rapid detection method provided by the invention is cheap and can realize rapid determination of the adsorptivity of the biomass charcoal material.

Description

technical field [0001] The invention relates to a rapid detection method for the adsorption performance of a biomass carbon material. The rapid detection reagent used is composed of organic alcohols such as methanol or ethanol. Background technique [0002] In contemporary society, environmental issues have attracted more and more attention, and biomass carbon materials are ideal materials for air purification. The adsorption performance of biochar material directly determines its ability to purify air. The existing methods for measuring the adsorption performance of biomass carbon materials are mainly divided into two categories: one is to use the specific surface area adsorption instrument to characterize the adsorption performance of carbon materials. The advantage of this type of method is that it measures accurately and can characterize the isothermal adsorption and desorption curves of carbon materials. The disadvantage is that the price of the specific surface area ...
