Problems solved by technology

However, since this method is carried out at room temperature (25°C), they cannot be fully acted, a good crystal structure cannot be obtained, and the yield is low; the second type of method is a hydrothermal method, which is a An excellent method for preparing metal complexes, under which the viscosity of water will decrease and the diffusion process will increase, which is conducive to the gradual action of reactants and the growth of crystals

Abstract

The invention discloses an organic complex ZnNa2(C10H4O8)2(H2O)10, a preparation method of the organic complex and application of the organic complex serving as a polycyclic aromatic hydrocarbon adsorbent. The preparation method of the organic complex ZnNa2(C10H4O8)2(H2O)10 includes the steps of enabling pyromellitic acid, zinc nitrate hexahydrate and sodium hydroxide with the molar ratio of 1:1-2:2.5-3.5 to be added into a reaction vessel, adding ultrapure water, placing the reaction vessel in a hydrothermal reaction kettle to be heated, enabling the temperature to be set to be 150-170DEG C, taking the reaction vessel out to carry out filtering, and obtaining the metal complex ZnNa2(C10H4O8)2(H2O)10. The metal complex prepared through the preparation method is mainly used as the polycyclic aromatic hydrocarbon adsorbent, and particularly has great practical significance in enabling MOF to be applied to polycyclic aromatic hydrocarbon detection.

Description

[0001] Statement on funding research and development [0002] This invention was funded by the Tianjin Natural Science Foundation (12JCZDJC21700) and Tianjin Normal University "Da Chuang Program" project (201210065024). technical field [0003] The invention belongs to the field of organometallic chemistry, and in particular relates to a metal organic complex compound of pyromellitic acid linking metal ions zinc and sodium and its preparation method, and a metal organic complex compound linking metal ion zinc and sodium of pyromellitic acid in adsorption and mixing Applications in polycyclic aromatic hydrocarbons. Background technique [0004] Metal-organic framework (MOF) is an inorganic-organic hybrid microporous crystal material, which is composed of metal ions and organic compounds through coordination. Different metal ions and different organic compounds can form a variety of MOF materials. And have different topology and porosity. Due to the variable structure, per...
