Catalytic membrane reactor on basis of nuclear track membranes and method for preparing catalytic membrane reactor

Abstract

The invention provides a catalytic membrane reactor on the basis of nuclear track membranes and a method for preparing the catalytic membrane reactor. The method includes S1, fixing target nuclear track membranes onto molds, placing the target nuclear track membranes and the molds into given buffer solution together, adding dopamine hydrochloride and sodium periodate into the given buffer solutionand carrying out magnetic stirring to obtain nuclear track membranes with porous channels modified by polydopamine; S2, washing the nuclear track membranes with the porous channels modified by the polydopamine by the aid of given washing agents, and carrying out hydrothermal reaction treatment to obtain the target nuclear track membrane reactor. The catalytic membrane reactor and the method havethe advantages that straight-through hole structures of the nuclear track membranes and physical and chemical properties of dopamine can be sufficiently utilized, and accordingly the catalytic membrane reactor is good in universality; the hydrophilicity of the catalytic membrane reactor can be effectively improved, accordingly, the flux of membranes can be effectively enhanced, and the suction filtration efficiency can be obviously enhanced in suction filtration procedures.

Description

technical field [0001] The invention relates to the technical field of membrane reactor preparation, more specifically, to a nuclear track membrane-based catalytic membrane reactor and a preparation method thereof. Background technique [0002] Since Fleischer successfully developed and commercialized the nuclear track membrane in the 1960s, the nuclear track membrane has been widely used in many fields such as medical treatment, industrial wastewater treatment, and anti-counterfeiting label preparation due to its structural advantages of penetrating through holes. . [0003] In order to take full advantage of the structural advantages of nuclear track membranes, a series of pore modification methods have emerged. Common methods for channel modification of nuclear track membranes include electrochemical plating, polymer grafting, etc. However, the number of reports that these modification methods can actually realize the modification in the channel is small, and it needs t...

AI Technical Summary

Problems solved by technology

However, the number of reports that these modification methods can actually realize the modification in the channel is small, and it needs to be realized under specific conditions, the universality is poor, and the operation is cumbersome.

At the same time, due to the use of these modification methods to increase the membrane surface thickness and the mass transfer resistance in the pores, the flux of the membrane becomes lower, and membrane fouling is more likely to occur.
