What to do if some tiny mercury beads fall off the floor?

Mercury balls that are not easy to sweep up, such as mercury balls that fall in low-lying places, uneven ground, or wall corners, should be adsorbed. Cut the shock-absorbing sponge for packaging into small pieces, press the mercury beads, and then gently pick them up, and the mercury beads will burrow into the sponge. If you twist or shake the sponge hard, the mercury beads will come out again, so handle it gently and quickly seal it in a plastic bag.

Where the sponge cannot reach, the method is to use a thin solder wire or fuse, which is folded in half many times to make a twist shape, and then activated in about 5% dilute hydrochloric acid, and can be used to adsorb mercury balls before drying after being removed. This twist-shaped adsorber is immediately sucked away by a gentle touch of the mercury ball. If the solder wire and fuse are thicker, they can be used directly after activation instead of covering them into a twist shape, but the adsorption efficiency is lower.

If there is a metal zinc wire with a smooth surface, it can be adsorbed with zinc wire, and for surface oxidizers, it is also necessary to activate it with hydrochloric acid. <>

Hurry up and open the door to keep it ventilated. Then I ran to the lab and stole some S powder. Thinking about it later, it is very unlikely that someone in a normal person's home will have a reserve of S elemental matter.

So if the mercury thermometer in your home is broken, the first thing to remember is to ventilate. Mercury is volatile (don't be afraid, it doesn't evaporate quickly), so ventilation is the most important. Even if a small amount of mercury rolls out of sight, as long as you ensure constant ventilation, it is not a big deal.

After ventilation, if there is no s, it is recommended to wear gloves and collect the mercury into an airtight container with the help of tools, and then. It seems that in China it can only be thrown into outdoor trash cans. Sprinkle sulfur powder in chemical laboratories is not as good as zinc powder and copper powder, and copper is the best to use usually.

If the requirements for the common things in life are particularly high, then I want to explain that there are no common things in life that can safely and thoroughly deal with mercury, just as you can't safely dispose of hydrofluoric acid with the common things in life. <>

Collect it in a container with an open opening outside the window, then close the windows of your home and let it air dry.

Sprinkle sulfur on top first, then sweep it off. Because after the volatilization of mercury, it is not good for the body to be inhaled. If sulfur is sprinkled on it, mercury sulfide will be formed. Mercury sulfide does not volatile. So it can be swept away.

Collect with a vacuum cleaner and dispose of it properly.

The most common method of fixing mercury is iodine fumigation. This method requires a certain concentration of iodine vapor to be created indoors, and the iodine vapor will react with mercury adsorbed on walls and furniture by itself to produce non-volatiles that are stable at room temperature. The method of iodine fumigation is as follows: take some iodine and break it into small particles, sprinkle it on the upwind of the wall roots, under furniture, etc., so that it will naturally sublimate.

If you close the doors and windows for several hours, and if you smell a strong iodine smell when you re-enter the room, the fumigation has been successful. Depending on the degree of contamination, gram-iodine is usually used per cubic metre of air. After the first fumigation, a dose of grams per cubic meter per day can be maintained for one to two weeks.

During the maintenance period, the room has a slight iodine smell and can be used normally. <>

You can sprinkle with an appropriate amount of fine sand and sweep it.

How do you clean up the mercury beads on the ground? You can pick it up with paper and put it in a trash can that cannot be **.
