Abstract

The invention discloses a method of extracting plant vessels from biomass material. The method comprises the steps of (1) weighing certain sodium hydroxide and sodium sulfite, adding into deionized water, and mixing well for full dissolution to obtain solution A; (2) adding plant leaves into the solution, and boiling on a heating stove for a certain time; (3) after boiling, washing repeatedly withdeionized water to obtain a product; (4) taking certain concentrated sulfuric acid solution with a measuring tube, adding deionized water, and mixing well to obtain solution B; (5) adding the productof step (3) into the solution B, performing ultrasonic treatment, extracting after ultrasonic to obtain massive biomass vessels. The method herein is suitable for acquiring massive high-purity biomass vessels; the method is simple, easy to perform, and low in cost.

Description

technical field [0001] The invention belongs to the field of carbon material preparation, in particular to a method for extracting plant ducts in large quantities. Background technique [0002] The rapid development of the world economy has led to excessive use of energy, and the rapid development of modern industry has sharply consumed fossil resources and caused a series of environmental problems. Traditional fossil resources are non-renewable, so resource and environmental issues are the great challenges faced by human beings today, and the utilization of renewable biomass energy has become an inevitable choice for the sustainable development of society. Plant conduits are a renewable resource that can be used to prepare carbon materials. [0003] Vessels are tubular structures in the xylem of plants that mainly transport water and inorganic salts; they are composed of a string of highly specialized tubular dead cells whose end walls are interconnected by perforations, a...
