Embodiment Construction

[0020] The above scheme will be further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present invention and not to limit the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to the conditions of specific manufacturers, and the unnamed implementation conditions are usually the conditions in routine experiments.

[0021] Example figure 1 As shown, the stacked nanomaterial solid phase extraction column includes the inner support part, namely the column core 1; the nanomaterial layer 2 of the middle material part, namely the electrospun nanofiber (containing aluminum foil as the dense thin fabric 3); the outer sealing Part is the aluminum foil adhesive layer 4.

[0022] Such as figure 2 As shown, the column core 1 is a solid cylindrical material (which can be made of polymer, metal, glass, etc.) without pollutant release after c...

Abstract

The invention discloses a stacked nano-material solid-phase extraction column. The stacked nano-material solid-phase extraction column consists of a column core, a nano-material and a sealing layer; a solid column body with a certain length is obtained by cutting; a dense thin shell fabric which is covered with a nano-material layer with certain weight uniformly wraps around the column core for a plurality of layers; an outer seal is fixed, so that the stacked nano-material solid-phase extraction column is formed. The manufacturing process of the solid-phase extraction column is simplified; the extraction columns manufactured in batches have the high reproducibility; particularly, for large-size and high-density liquid samples, the column passing resistance is low, the speed is high, and the extraction time is shortened.

Description

technical field [0001] The invention belongs to the technical field of separation, purification and concentration of micro or trace substances, in particular to a stacked nano material solid phase extraction column. Background technique [0002] Separation technology has been involved in all aspects of production and life in modern society. Separation and extraction of precious elements or compounds, trace analysis of food and environment, DNA sequence analysis in life sciences, determination of proteome, carbohydrates, etc. all require advanced Separation and enrichment technology. At present, people have deeply realized that separation technology is a bottleneck hindering the industrialization development of environmental protection technology, biotechnology, food and medicine and other industries. Achieving the effect of separation and purification through adsorption is one of the main ways to solve the problem of separation and enrichment, and the application of new sep...
