Embodiment 1

[0108] The composition of the oxidation decontamination gel prepared in this embodiment by weight percentage is as follows:

[0109] Gel substrate silicon dioxide 14%, surfactant AT904 8%, thixotropic multiplier T2-815 1%, strong oxidant hexammine cobalt trichloride 8%, hydrochloric acid 9%, modifier kaolin (purchased in Inner Mongolia Tianzhijiao Kaolin Co., Ltd.) 1%, defoamer n-octanol 1%, color indicator sodium disulfame 0.5%, water 57.5%.

[0110] The specific preparation method of oxidation decontamination gel is as follows:

[0111] (1) Add the gel base material of the formula amount into the water of the formula amount, fully stir and emulsify until uniform;

[0112] (2) Add the ingredients of other formula quantities except the gel base material, water, surfactant, and thixotropic multiplier and mix evenly, and seal up for use;

[0113] (3) Before use, add the surfactant and thixotropic multiplier in the formulated amount and mix well.

[0114] After defoaming the o...

Abstract

The invention belongs to the technical field of radioactive decontamination, and relates to oxidation decontamination gel as well as a preparation method and application thereof. The oxidation decontamination gel is prepared from the components including, by weight, 5%-15% of a gel base material serving as a gel framework material, 5%-10% of a surfactant, 0.5%-5% of a thixotropic multiplication agent, 3%-20% of a strong oxidant, 3%-20% of acid, 1%-5% of a modifier and 25%-82.5% of water. By means of the oxidation decontamination gel as well as the preparation method and application thereof, the oxidation decontamination gel can be better prepared, the prepared oxidation decontamination gel is the oxidation gel for decontamination of second-generation radioactive contaminated metal, water washing is not needed after decontamination is completed, the residual oxidation decontamination gel can be automatically dried and cracked, and a brush is conveniently used for cleaning, or a dust collector is used for sucking and collecting the gel, so that secondary liquid waste is not generated in the decontamination process, and the gel is more suitable for field decontamination.

Description

technical field [0001] The invention belongs to the technical field of radioactive decontamination, and relates to an oxidative decontamination gel and its preparation method and application. Background technique [0002] After decades of development, my country's nuclear industry has produced a huge amount of radioactively polluted metals. Deep decontamination of radioactively contaminated metals reduces their surface contamination levels, helping to reduce the amount of contaminated metals while protecting radiation workers from less exposure. [0003] Oxidizing substances have a corrosive effect on metals. Therefore, in the field of radioactive decontamination, strong oxidizing substances can be used to corrode the metal surface to achieve the removal of radioactive substances. Oxidizing substances commonly used for this purpose include high-valent silver ions, high-valent cerium ions, and high-valent cobalt ions. [0004] Commonly used oxidative decontamination methods...
