Palm tree bark adsorbent with good stability

Abstract

The invention discloses a palm tree bark adsorbent with good stability. The palm tree bark adsorbent comprises the following substances in parts by weight: 11-14 parts of populus yunnanensis sawdust, 35-46 parts of palm tree bark, 25-34 parts of cypress sawdust, 3-7 parts of sodium carbonate, 11-16 parts of lightweight powder, 6-7 parts of maleic anhydride, 6-16 parts of zinc borate, 3-4 parts of a silane coupling agent, 3-11 parts of ferric oxide, 5-9 parts of kieselguhr, 12-14 parts of solid gedanite, 10-14 parts of sodium borate and 20-26 parts of pyromellitic dianhydride. The palm tree bark adsorbent has the advantages of good physical and chemical stability, excellent mechanical strength, large adsorption capacity, high mechanical strength, good abrasive resistance, high adsorption speed and good desorption performance, low energy consumption, simplicity in operation and easiness of industrial production, has the advantages of a solid-phase carrier material of being good in stability, being a natural green product and allowing materials to be renewable and wastes to be biodegradable, and belongs to a clean production process.

Description

technical field [0001] The invention relates to a palm bark adsorbent with good stability. Background technique [0002] Ionic liquids are generally composed of specific organic cations (such as imidazole, pyridine) with relatively large volume and asymmetric structure and relatively small inorganic anions (such as Cl-, Br-, etc.) at room temperature or near room temperature. liquid substance. Room temperature ionic liquid is an excellent solvent, which can dissolve polar and non-polar organic and inorganic substances, is easy to separate, and can be recycled. It has a wide liquid range, no vapor pressure, no volatilization, and no environmental pollution. It is known as a green solvent. [0003] Immobilizing the ionic liquid can obtain the loaded ionic liquid or a solid material with an ionic liquid structure on the surface. This not only combines the advantages of solid-phase carrier materials, but also solves the problem of loss of ionic liquids in water environments, ...

Problems solved by technology

However, both of these two methods consume a large amount of toxic organic solvents and take a long time, which is easy to cause secondary pollution to the environment.

Due to the complex matrix of the sample, it brings difficulties to the detection
