PAPER INDUSTRY EDTA chemical - Coggle Diagram
PAPER INDUSTRY
EDTA chemical
Physical properties of EDTA chemical
Uses of EDTA chemical
When EDTA is used on the "brown side," that is, before bleaching, it is usually always returned and consumed in the recovery boiler.
Adding EDTA on the brown side, that is, after pulping but before oxygen acid treatment, has been shown to reduce the quantity of catalyst needed in system call bleaching processes.
EDTA is a white powder that dissolves in a solution of sodium hydroxide, sodium carbonate, and ammonia.
With alkali metals, valuable minerals, and transition metals, it can form very stable water-soluble complexes
HEALTH IMPACT
Effects of EDTA chemical exposed to workers
Exposure pathway and target organ
Control measure
Chemical procedures for highly annoying and toxic compounds are covered.
Using local exhaust ventilation for chemicals that may be harmful with a single exposure.
Using general circulation to keep skin and eye irritants at the industry.
The route of exposure pathway and target organs was inhalation and respiratory system.
If swallowed, it can be harmful. It's exposure by inhalation include it's possible that this will irritate your lungs.
Symptoms and effects of skin contact was it irritates the skin.
After that, it's exposure by eye contact: Irritates the eyes severely.
Abdominal pains, nausea, vomiting, diarrhea, headache, low blood pressure, skin disorders, and fever are all possible side effects of EDTA.
Using more than 3 grams of EDTA each day, or taking it for more than 5 to 7 days, is extremely dangerous.
If you consume too much, may risk kidney injury, critically low calcium levels, and death.
ENVIRONMENTAL IMPACT
Changes the chemical to the environment
Underlying causes of impacts
Mitigations
The EDTA salt is known for its good metal ion coordination behavior.
Heavy metals attached to sediments can be dissolved by EDTA and heavy metal formation can be prevented, increasing the cycle of heavy metals in water.
These metal complexes, on either side, are unlikely to be as soluble as free metal ions.
Because EDTA is a persistent chemicals, they contribute to the chemicalization of the marine environment.
EDTA is water-soluble it is eventually released into the environment along with wastewater. In general, natural environments are unaffected by EDTA.
In the environment, EDTA behaves as a persistent substance, and its contribution to heavy metal solubility and remobilization processes is a serious problem.
