Embodiment 1

[0029] A hazardous chemical adsorbent based on a polymer gel material, comprising 100 parts of cross-linked polyacrylamide, 500 parts of sodium bicarbonate, 300 parts of calcium carbonate, 3 parts of thymol blue, 1 part of methyl red, and quartz sand 96 parts are accurately weighed with a balance in proportion, mechanically mixed and stirred evenly and placed in a container for later use. The adsorption amount was detected, and the adsorption amount of 10ml hydrochloric acid solution (37% v / w) was measured to be 19 grams, and the pH value of the solution was 7.2.

Embodiment 2

[0031] A dangerous chemical adsorbent based on a polymer gel material, 250 parts of cross-linked polyacrylic acid, 260 parts of sodium bicarbonate, 400 parts of magnesium hydroxide, 2 parts of bromothymol blue, 2 parts of methyl orange, and 86 parts of quartz sand The parts are accurately weighed with a balance according to the proportion, mechanically mixed and stirred evenly, and placed in a container for later use. The adsorption amount was detected, and the adsorption amount of 10ml hydrochloric acid solution (37% v / w) was measured to be 16 grams, and the pH value of the solution was 7.1.

Embodiment 3

[0033] A dangerous chemical adsorbent based on a polymer gel material, 150 parts of cross-linked polyacrylic acid, 300 parts of aluminum hydroxide, 470 parts of boric acid, 2 parts of thymol blue, 2 parts of methyl orange, and 76 parts of quartz sand Accurately weigh with a balance in proportion, mechanically mix and stir evenly and place in a container for later use. The adsorption amount was detected, and the adsorption amount of 10ml sodium hydroxide solution (1N v / w) was measured to be 9 grams, and the pH value of the solution was 7.6.

Abstract

The invention relates to a dangerous chemical adsorbent based on a polymer gel material and an application method thereof and belongs to the technical field of processing of high polymer material. The polymer gel adsorbent is composed of 10-300 parts of polymer gel materials, 400-900 parts of neutralizers, 1-10 parts of color reagents and 10-100 parts of anti-caking agent. When acid-base liquid waste leaks, the polymer gel adsorbent is scattered on the periphery and surface of the acid-base liquid waste, so that the function of preventing proliferation is achieved, and then the state of neutralizing and absorbing progress is quickly judged according to the color indication of PH color reagent contained by the polymer gel adsorbent, and the residue solid achieving neutral PH and formed by absorbing is collected and duly handled. Compared with the singly used inorganic mineral absorbing material, the polymer gel adsorbent material adopted for mixing with the neutralizer in appropriate proportion according to the invention has the advantages that the water absorbing efficiency of the polymer gel adsorbent is greatly increased, the adsorbent dosage is reduced, the corrosivity of the chemicals also can be reduced due to the usage of the neutralizer and the risk of onsite rescuer is relieved.

Description

technical field [0001] The invention relates to a hazardous chemical adsorbent based on a polymer gel material and a preparation method thereof, belonging to the technical field of polymer material processing. Background technique [0002] Hazardous chemicals refer to highly toxic chemicals and other chemicals that are poisonous, corrosive, explosive, flammable, and combustion-supporting, and are harmful to the human body, facilities, and the environment. [0003] The leakage of dangerous chemicals will bring great harm to the environment, life and property. Especially strong corrosive acids and alkalis, because of their wide application in industrial enterprises and scientific research and experimental sites, their leakage is more frequent, and serious accidents caused by strong acid and strong alkali leakage occur from time to time. [0004] For the disposal of hazardous chemical leakage, a basic principle is to treat highly toxic, poisonous and harmful hazardous chemical...
