Chemical Property/Description

Brown black or dark brown powder.Alcohol solution is blue-red, It's stimulating. Al, Fe, Zr complex indicator, can be used for fluorescence analysis of aluminum, determination of water hardness and so on.



Main Uses:

It is mainly used for dyeing loose wool, top and cloth. It is generally used to dye black, not grey. It can also be used for dyeing silk, nylon, leather, etc. Pure products can also be used as indicator Chemicalbook agents. Wool fabrics pretreated with chromium acetate can be printed directly with this product. Dyeing should use the post-medium method, the amount of chromium salt should not be large, generally 1%-1.5% of the weight of the dye.

Used as a complex indicator for determination of calcium, magnesium, manganese, zinc, etc.

Al, Fe, Zr complex indicator, fluorescence analysis of aluminum, determination of water hardness.

Complexation indicator; Determination of calcium, magnesium,  manganese and zinc; Determination of aluminum by fluorescence analysis; Determination of water hardness.
