How to clean the activated aluminum oxide container

As we all know, activated alumina is a very widely used chemical reagent, and then used in a variety of occasions, although the use is too much, but after the use of container cleaning has been people's operating problems, so in order for users to better use, we will understand its cleaning requirements.

Activated alumina is mainly and with a variety of washing liquid, through physical and chemical methods to remove the dirt on the glass, according to the requirements of the experiment and the nature of the glass and the degree of contamination to select different washing liquid and methods tap water flushing with a brush on water, can dissolve the water-soluble matter, can also be washed off the dust attached to the surface of the instrument.

The use of this method is to pay attention to the fact that the activated alumina in the container is a small number of can be used in this method, and the amount is stopped. After the tap water is washed, it can be carefully washed with a brush dipped in soapy water and washing powder. When washing, it should be washed to make more foam, and then rinsed with tap water, rinsed three times with boiled water, and drained naturally on a drying rack or placed in the oven to dry for later use.

During the experiment, if you encounter a hidden point of activated alumina in the corner of the container that is difficult to clean, you must not treat it with water, because a relatively large amount of activated alumina encounters water, resulting in rapid local temperature progress, and then causing the container to burst. You can choose to soak in 45% urea solution to dissolve activated alumina, and then rinse with water, if it is still not clean, you can soak in potassium human acid cleaning solution for 4-6h, and then wash activated alumina with water.

Strictly following the cleaning method of the activated alumina container not only ensures the safety of personnel, but also prevents recontamination caused by unclean cleaning.
