How to Dispose of Iodine Properly

When dealing with iodine, it’s vital to fully understand what it is and how it affects your body.

This type of chemistry can be complex and confusing, so consult an expert if necessary. So, how do you dispose of iodine properly?

Disposing of iodine properly is difficult because iodine is toxic. The Agency for Toxic Substances and Disease Registry (ATSDR) says it is safe to flush iodine away with flushable wipes.

But you should never flush these wipes down the toilet. Instead, you should place them in the trash.

Also, you should wash your hands after handling iodine.

Can Iodine Go Down Drain?

Then, you should get rid of the iodine monochloride solutions by recycling them or getting rid of them in the way that your local government or the company that made the disinfectants tells you to.

When iodine monochloride combines with chlorine in swimming pool water, it becomes hypochlorous acid, which is highly corrosive to eyes and skin.

When the solution is dumped into the sewer system without being cleaned first, the pH of the effluent drops and the concentration of free chlorine rises significantly. This is because the hypochlorous acid quickly breaks down into chlorine gas.

Is Iodine a Hazardous Waste?

Iodine may be harmful if swallowed, inhaled, or absorbed through the skin.

Dispose of containers in accordance with local refuse disposal regulations.

Disinfect containers with a high-pressure water hose after rinsing them in plenty of diluted cleanser.

If iodine is mixed with sand, it should be disposed of by burying it at least 5 cm deep in the ground.

An explosion hazard is the disposal of potassium iodide in a fire.

Fallout from a fire of potassium iodide is handled in the same way as fallout from a fire of potassium carbonate, except that no fire-fighting foam should be used.

The first time you use iodine to sterilize, you risk burning yourself.

Iodine solutions are often used to treat wounds and clean or sterilize medical tools and equipment.

Iodine is a salt found in sea plants called kelp. It is used to make cough medicine.

Why Is Iodine Toxic to Humans?

Your thyroid gland requires sufficient amounts of this mineral to function normally.

Excessive nonradioactive and radioactive iodine exposure can cause serious health problems such as thyroid cancer and noncancerous thyroid diseases, including goiters and hypothyroidism.

Thyroid gland damage may have an impact on pregnancy, fertility, and reproductive function in women, as well as growth and development in children.

How to Properly Dispose of Iodine

Iodine monochloride is a disinfectant used for cleaning and disinfecting surfaces in hospitals, laboratories, nursing homes, and other healthcare facilities.

When iodine monochloride comes into direct contact with the skin, it can cause irritation to the skin, eyes, nose, throat, and lungs.

When using and disposing of this chemical product, it is important to always wear gloves, protective clothing, and safety glasses to avoid the risk of skin irritation and skin burns.

Place the solution in an appropriate container according to the amount being used.

Because iodine monochloride reacts with other chemicals under certain conditions, it must be stored in tightly sealed containers and kept in a cool, dry place away from any source of heat or ignition to prevent decomposition.

Do not store above 30°C (86°F) to avoid the formation of harmful fumes.

Iodine monochloride is toxic to fish and aquatic invertebrates and should be disposed of according to federal, state, and local regulations.

If you spill iodine monochloride, wipe it up immediately with absorbent materials such as a disposable towel or a spill kit made of a shovel with a polyethylene bag to collect the material.

When working with liquid disinfectants, always wear protective equipment such as safety glasses, rubber gloves, and appropriate clothing.

Young Adult Science Experiments

If you deal with children or young teens in your life, check out these fun science experiments that they can do on their own at home.

The Disappearing Iodine experiment, like Cesa’s, is one that kids love to do over and over again.

Disodium sulfate, like sodium bicarbonate, is a salt used to make cleaning agents that bubble up when dissolved in water.

Working In a Laboratory

If you’re reading this because you work as a lab professional, here’s some helpful advice on handling chemicals and working in a laboratory environment.

The video explores what a laboratory is and what its components consist of: benches for equipment storage; fume hoods for safe handling of chemicals; clean benches for performing work; storage rooms for hazardous chemicals;.

Since iodine has properties that cause it to oxidize, a reducing agent like sodium carbonate should be added to neutralize the acid that forms during oxidation and stop the copper from corroding more.

This process basically wipes out all the existing cells and creates space for new cell growth.

Waste properties are classified according to the following: substances that are harmful to humans if consumed or inhaled,Chronic toxicity refers to substances that build up in the body and cause permanent damage, ecotoxicity-substances.

Corrosivity includes oxidation-reduction reactions such as rust formation or tarnishing, so any substance capable of causing an oxidation-reduction reaction is corrosive to some degree.

Recommendation from WISER

Iodine that has been used should be disposed of in accordance with local regulations.

Iodine should only ever be handled in well-ventilated areas because it releases fumes when it is heated to high temperatures or when exposed to light.

WISER demands that the manufacturers of this chemical provide instructions for the safe handling and disposal of the chemical, as well as emergency response information for handling spills.

These considerations include the possibility of mixing with soil materials, release into the environment or groundwater, and the potential of contact by non-target organisms, including wildlife.

Iodine may be neutralized by combining it with an alkali such as sodium carbonate.

WISER says that iodine should only be burned in medical waste incinerators that are licensed to do so.

Think about the chemical’s physical and chemical properties and what will happen to it in the environment when thinking about how to get rid of it.


Iodine can be reused by using calcium hydroxide and hydrogen peroxide to get rid of organic pollutants.

Many companies that make iodine have started to collect and recycle their used iodine, but more research is needed to find out if this is as safe and effective as burning it.

If you deal with iodine on a regular basis, it may be a good idea to investigate your options for recycling it.

Nutrition corporations, high school science classes, and pharmaceutical companies are some of the entities that use large amounts of elemental iodine every day.

It may be worthwhile to contact these entities to see if they would be interested in participating in a recycling program in your area.

Iodine is a harmful chemical that should be disposed of properly.

Iodine can cause health issues in humans and animals if it gets into the water or soil. In addition, iodine can cause damage to the environment.

Therefore, it’s important to dispose of iodine properly. The safest way to dispose of iodine is to bury it underground or put it in a sealed container.
