alias： Green alum and iron alum

English name ferrous sulfate heptahydrate； green vitriol； iron vitriol

Molecular formula： FeSO4·7H_twoO

Physicochemical properties：： Blue green monoclinic crystals or particles, odorless. relative density10.898。 Melting point: 64 ℃. Soluble in water (48.6/100ml water at five0 ℃), slightly soluble in alcohol and soluble in anhydrous methanol. Six crystal water is lost at 64 ~ 90 ℃, and all crystal water is lost when heated to 300 ℃. Red heat decomposes into ferric oxide and releases sulfur dioxide. Sulfur trioxide. It is corrosive and will be weathered in dry air. Easily oxidized by deliquescent air.

purpose： It is usually used as flocculant in sewage treatment. In agriculture, it can be used as a pesticide to prevent wheat smut, scab of apples and pears and rot of fruit trees; It can also be used as fertilizer to remove moss and lichens from tree trunks. It is the raw material for manufacturing magnetic iron oxide, iron oxide red and iron blue inorganic pigments, iron catalyst and polyferric sulfate. It is used as local astringent and blood tonic in medicine. In addition, it is also used as chromatographic reagent. Edible grade is used as nutritional supplement, such as iron fortifier and fruit and vegetable colorant. Feed grade ferrous sulfate is used as an iron supplement in feed processing.

Technical indicators:

National standardsGB 10five31－two006：

use于廢water處理的客戶還可以直接選use鈦白粉廠副產(chǎn)的硫酸亞鐵，該副產(chǎn)硫酸亞鐵未離心烘干，所以含water量較高，含量一般在8five-90%. Because it is an industrial by-product with low price, it is welcomed by many customers (please note that this product may be dissolved by its own water in summer and cannot be stored for a long time).

如需長(zhǎng)途運(yùn)輸，則可以u(píng)se烘干過了硫酸亞鐵，含量可達(dá)More than 98%, long-term storage will not have the phenomenon of water absorption and dissolution.

Several commodities of our company, ferrous sulfate heptahydrate, are as follows:

1）副產(chǎn)硫酸亞鐵：未干燥的產(chǎn)品，含量約8five-90%，工業(yè)廢water處理use，價(jià)格低廉，five0公斤編織袋裝。

two）普通硫酸亞鐵：初步脫water的國(guó)標(biāo)產(chǎn)品，含量90%，工業(yè)water處理或自來water處理use，twofive公斤編織袋裝。

3）烘干硫酸亞鐵：經(jīng)過烘干的，含量98%，適合各種water處理、土壤改良etc.purpose，可長(zhǎng)期儲(chǔ)存。

In addition, our company can also customize ferrous sulfate monohydrate, containing irontwo8-30%的粉末或粒度不同的塊狀物。

packaging and storage ：

根據(jù)use戶要求可選use散裝或聚乙烯塑料袋、草袋或塑料編織袋包裝，每袋凈重twofivekg或five0kg。
