[0021] (1) ZrHIO 6 4H 2 Preparation of O

[0022] Take 1.0mmol of ZrO(NO 3 ) 2 Dissolve in hot 200mL dilute nitric acid (H 2 O / HNO 3 The volume ratio is 5:1) and keep stirring until it is completely dissolved. At the same time, weigh 1.5mmol of H 5 IO 6 Dissolve in 20mL deionized water to obtain a periodic acid solution. Then this solution was added dropwise to ZrO(NO 3 ) 2 And dilute nitric acid mixed solution, and keep stirring for 30 minutes. The obtained precipitate was washed three times with deionized water (50 mL of deionized water each time), and after centrifugation, it was dried in an oven at a temperature of 60 ° C for 24 hours to obtain ZrHIO 6 4H 2 O samples.

[0023] (2)ZrHIO 6 4H 2 Representation of O

[0024] From figure 1 The SEM image shows that ZrHIO 6 4H 2 The O samples have random morphology with a size of 5-200um. figure 2 The EDS results of the SEM images show that the ratio of the number of atoms Zr, I, and O contained in the sample...

Abstract

The invention discloses application of ZrHIO6.4H2O and provides an application example of the compound for the first time. ZrHIO6.4H2O as a catalyst is capable of degrading organic dye pollutants such as rhodamine B(RhB) and methylene blue (MB) even being kept completely in a dark place under a room temperature. In a degradation experiment, the activitity of ZrHIO6.4H2O is not decreased after ZrHIO6.4H2O is repeatedly used for three times, and the activity of ZrHIO6.4H2O is still kept well and has no obvious decrease after ZrHIO6.4H2O is repeatedly used for multiple times continuously. ZrHIO6.4H2O is simple in preparation method and wide in preparation condition, can realize catalyze degradation of organic dyes without dependence on illumination under a condition of room temperature, and is high in durability and beneficial to popularization and application.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control and relates to zirconium periodate (ZrHIO 6 4H 2 O) Application of a novel catalyst in the degradation of organic dye pollutants. Background technique [0002] With the increase of population, the scale of the printing and dyeing industry in the world is constantly expanding. The large amount of organic dye pollutants discharged by this industry has become an important source of water pollution in the world. Semiconductor photocatalysis technology can directly use sunlight to efficiently oxidize and degrade dye pollutants at room temperature. Therefore, it is a favorable way to control environmental pollution by making full use of sunlight to degrade dye pollutants through photocatalytic technology. Because ultraviolet light only accounts for about 4% of the total energy of sunlight, while visible light accounts for about 46%, so the key to utilizing solar energy is to u...
