1. The function and use of ferrous sulfate

Ferrous sulfate can be used to make iron salts, iron oxide pigments, mordants, water purifiers, preservatives, disinfectants, etc.

One, water treatment

Ferrous sulfate is used for the flocculation and purification of water and the removal of phosphate from urban and industrial sewage to prevent eutrophication of water bodies.

Two, reducing agent

A large amount of ferrous sulfate is used as a reducing agent, mainly reducing chromate in cement.

Three, medicinal

Ferrous sulfate is used to treat iron deficiency anemia; it is also used to add iron to food. Long-term excessive use may cause side effects such as abdominal pain and nausea.

Medicine can also be used as a local astringent and blood tonic, and can be used for chronic blood loss caused by uterine fibroids.

Four, coloring agent

1. The production of iron tannate ink and other inks requires ferrous sulfate. The mordant for wood dyeing also contains ferrous sulfate.

2, ferrous sulfate can be used to stain concrete into a yellow rust color.

3, woodworking uses ferrous sulfate to dye maple with silver color.

4. Agriculture

Adjust the pH of the soil to promote the formation of chlorophyll (also known as iron fertilizer), which can prevent yellowing disease caused by iron deficiency in flowers and trees. It is an indispensable element that loves acidic flowers and trees, especially iron trees. It can also be used as a pesticide in agriculture to prevent wheat smut, scab of apples and pears, and rot of fruit trees; it can also be used as a fertilizer to remove moss and lichen on tree trunks.

6. Analytical Chemistry

Ferrous sulfate can be used as a chromatographic analysis reagent.

2. The pharmacological effects of ferrous sulfate
1. Main ingredient: ferrous sulfate.

2, traits: tablets.

3. Function and indication: This product is a specific medicine for the treatment of iron deficiency anemia. Clinically, it is mainly used for iron deficiency anemia caused by chronic blood loss (menorrhagia, hemorrhoid bleeding, uterine fibroids bleeding, hookworm disease blood loss, etc.), malnutrition, pregnancy, childhood development, etc.

4. Usage and Dosage: Oral: 0.3 ~ 0.6g for adults, 3 times a day, after meals. 0.1～0.3g for children, 3 times a day.

5. Adverse reactions and attention:

is irritating to the gastrointestinal mucosa and can cause nausea, vomiting, epigastric pain, etc. Taking it after meals can reduce gastrointestinal reactions.

A large amount of oral administration can cause acute poisoning, gastrointestinal bleeding, necrosis, and shock in severe cases.

6. Others: Iron combines with hydrogen sulfide in the intestine to generate iron sulfide, which reduces hydrogen sulfide and reduces the stimulating effect on intestinal peristalsis. Medical|Education Network Editor can cause constipation and black stool. It is necessary to tell the patient in advance so as not to worry.

Peptic ulcer disease, ulcerative colitis, enteritis, hemolytic anemia, etc. are forbidden.

Calcium, phosphates, tannin-containing drugs, antacids and strong tea can precipitate iron salts and hinder their absorption.

Iron agent and tetracyclines can form complexes and interfere with each other’s absorption.

3. Matters needing attention when using ferrous sulfate in medicine
Ferrous sulfate monohydrate contains 19-20% iron and 11.5% sulfur. It is a superior iron fertilizer. Acid-loving plants are often used to show the disease prevention and control methods at the time. Iron constitutes plant chlorophyll, iron deficiency, green chlorophyll makes plants prevent the onset of diseases, and light yellow leaves. Water ferrous sulfate solution can be supplied to plants, can receive and use iron, ferrous sulfate and can reduce alkaline soil. A ferrous sulfate water, 0.2% -0.5% of the mortal directly treats the basin soil, which may have a certain impact, but because the soil water dissolves iron, it will soon be fixed and destroyed by the fixed insoluble iron compound. For loss, you can use 0.2-0.3% ferrous sulfate solution on plant foliage. Because the iron activity in the plant is small, it should be sprayed 3 to 5 times from time to time so that the leaves can visit the iron solution, so that better results can be obtained.

Five precautions for ferrous sulfate in medicine:

1. When taking iron, do not take it with strong tea and antacids (such as sodium bicarbonate, phosphate). Tetracyclines and iron can form complexes and interact with each other.

2. When taking syrup or solution, you should use a straw to prevent your teeth from turning black.

3. For patients with distinct local gastrointestinal symptoms, the first oral dose can be reduced (gradually added in the future), or it can be taken between meals to reduce gastrointestinal reactions.

4. The storage of iron should be far away from children to prevent them from being swallowed or swallowed by mistake.

5. Patients with non-iron deficiency anemia and severe liver disease should not be treated with iron.

Use sulfuric acid and by-product titanium dioxide to receive combustion ash water treatment plan for ferrous sulfate. Existing techniques, burning more ash as a dregs disposal site, receiving titanium dioxide and by-product ferrous sulfate, have no reliable and safe outlets. The cost of processing these two wastes is high, difficult, and lacks disposal. Ferrous sulfate can be created using titanium dioxide and by-product ferrous sulfate solution water as the slag discharge water of the combustion furnace. Titanium dioxide and by-product ferrous sulfate solution are proportional to 20 ~ 135 g FeSO # -[4]/kg dry ash Fly ash slag disposal discharge pit, ferrous sulfate and slag discharged from ash, titanium dioxide and alkaline acid water are used in the pit for 0.5 to 1 hour after the anaerobic stage, the same chromium, fly ash, and slag are transferred to the air in the pit After exposure to oxidation for 1 to 5 hours, the pH value of the oxidized residue is limited to 9 to 11 in the filtrate, so that the oxidation method of heavy metals in the ash process will not be changed. The creative process of ferrous sulfate is simple, easy to waste, reduce the cost of effective treatment and drainage, and reduce burning ash and titanium dioxide waste acid. The pollution of by-products.

Four, several issues that need attention when taking ferrous sulfate
Among the many iron agents, ferrous sulfate is still the basic medicine for the treatment of iron deficiency anemia due to its less side effects and low price. However, the following issues should be paid attention to in the specific clinical application of the drug

1. Oral preparations of ferrous sulfate can cause gastrointestinal reactions such as nausea, vomiting, epigastric pain or diarrhea. It should be taken after or at the same time with meals, and should not be used with tea, coffee, or milk. Patients with ulcer disease are not allowed to use oral preparations, and can switch to iron preparations for parenteral administration.

2. It will turn black during the medication, so don’t panic.

3. In order to improve the absorption rate of iron, it can be taken together with vitamin C.

4. For achlorhydria, it is advisable to take it with dilute hydrochloric acid to promote iron absorption.

5. Avoid taking tetracycline, tannic acid, cholestyramine, bile-lowering tablets, sodium bicarbonate and pancreatin preparations at the same time.

6. After the treatment makes the hemoglobin normal, the patient still needs to continue taking iron for 1 month, and then taking the medicine for 1 month at 6 months, the purpose is to replenish the iron stored in the body.
