Ferric chloride is an important industrial ferric salt, which not only has a good effect in water treatment, but also is the most commonly used raw material in industrial production.

The importance of ferric chloride needs to be guaranteed by the product quality of ferric chloride. China has a professional index of ferric chloride, that is, GB / t6678-2003 has made the corresponding standard of ferric chloride. Ferric chloride, which can not meet the quality standards, are unqualified products. If these products are used, they will produce very poor results, and even have certain potential safety hazards.

According to the quality inspection standard of GB / t6678-2003, when sampling ferric chloride, the thickness of 5cm on the surface should be removed, and the sampler should be vertically inserted into half of the depth of the center of the bag for sampling, and the sampling should not be less than 500g. Then the relevant test of ferric chloride is carried out to find out whether ferric chloride is a qualified product.

Therefore, when purchasing ferric chloride, users need to have the corresponding qualified additional test book. It is better to select the manufacturer with credit guarantee for inquiry and purchase, so as to buy suitable high-quality ferric chloride products.
