Problems solved by technology

When the existence form of photocatalyst is changed from suspended state to supported type, the biggest change is that the specific surface area is greatly reduced, and the adsorption and light absorption efficiency of the catalyst are thus reduced, which has a certain impact on the photocatalytic activity.

Abstract

The invention relates to a preparation method of an interface plasma modified and amphiphilic fiber-based purifying material. The preparation method comprises the following steps: (1) ultrasonically cleaning a fabric through an organic solvent, and then processing through a detergent to obtain the processed fabric; (2) placing the processed fabric into a plasma processing instrument, and processing in a glow discharge way at normal pressure so as to obtain a modified fabric; (3) adding bismuth nitrate to salpeter solution, and dropping a wetting agent and an alkaline agent to obtain solution A; adding metavanadate to the water, and adding a thickening agent and sodium hydroxide solution to obtain solution B; (4) dropping the solution B to the solution A to react, and filtering and drying to obtain an unactivated photocatalyst body; (5) adding the unactivated body to strong acid, an oxidization stabilizer and a water to react, and carrying out water washing and filtration to obtain the filtrate which is the activated photocatalyst body solution; and (6) dipping the modified fabric into the activated body solution, processing with boiled water, and drying to obtain the interface plasma modified and amphiphilic fiber-based purifying material. The preparation method is simple, low in cost, free from secondary pollution, easy for industrial production, and wide in application prospect.

Description

technical field [0001] The invention belongs to the field of preparation of purification materials, in particular to a preparation method of interface plasma modified amphiphilic fiber-based purification materials. Background technique [0002] Since the 20th century, the global industrial wastewater pollution problem is increasingly restricting the progress of human civilization. The printing and dyeing industry is a major industrial wastewater discharge, accounting for about 1 / 10 of the total industrial wastewater discharge. With the rapid development of economy and science and technology, my country's textile printing and dyeing industry has entered a period of rapid development, the discharge of printing and dyeing sewage has also increased rapidly, and the environmental pollution has become increasingly serious. Printing and dyeing wastewater is characterized by a large amount of water, high chemical oxygen demand and biochemical oxygen demand, deep color, residual dyes...
