Product introduction

Ferrous sulfate is an inorganic substance with the chemical formula of FeSO4 and the appearance of white powder without odor. Its crystal hydrate is heptahydrate at normal temperature, commonly known as "green alum", light green crystal, which is weathered in dry air, oxidized to brown basic ferric sulfate in wet air, becomes tetrahydrate at 56.6 ° C, and becomes hydrate at 65 ° C. Ferrous sulfate is soluble in water and almost insoluble in ethanol. Its aqueous solution oxidizes slowly in the air when it is cold, and oxidizes quickly when it is hot. Adding alkali or dew can accelerate its oxidation. Relative density (D15) 1.897. It is irritating.

Purpose

1. Water treatment

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

2. Reducing agent

B. Ferrous sulfate can be used to dye the concrete into yellow rust color.

C. The maple is dyed with silver color with ferrous sulfate for carpentry.

5. Agriculture

Regulate the soil acidity and alkalinity, promote the formation of chlorophyll (also known as iron fertilizer), and prevent and cure the yellowing disease of flowers and trees caused by iron deficiency. It is an indispensable element of acid-loving flowers and trees, especially iron trees. It can also be used as pesticide in agriculture to prevent and control wheat smut, apple and pear scab, and fruit tree rot; It can also be used as fertilizer to remove moss and lichen from tree trunks.
