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于废water处理的客户还可以直接选use钛白粉厂副产的硫酸亚铁，该副产硫酸亚铁未离心烘干，所以含water量较高，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).

如需长途运输，则可以use烘干过了硫酸亚铁，含量可达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）副产硫酸亚铁：未干燥的产品，含量约8five-90%，工业废water处理use，价格低廉，five0公斤编织袋装。

two）普通硫酸亚铁：初步脱water的国标产品，含量90%，工业water处理或自来water处理use，twofive公斤编织袋装。

3）烘干硫酸亚铁：经过烘干的，含量98%，适合各种water处理、土壤改良etc.purpose，可长期储存。

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

packaging and storage ：

根据use户要求可选use散装或聚乙烯塑料袋、草袋或塑料编织袋包装，每袋净重twofivekg或five0kg。
