CAS:Black 7984 is a magnetic inkjet pigment that is composed of a black pigment, magnetic particles, and an acid. The pigment has been shown to be efficient in the removal of heavy metals from water and soil. Black 7984 can be used as an additive in paints, coatings, and inks. The magnetic particles are coated with an acid that reacts with heavy metals to form a metal salt that can be removed by filtration or adsorption. Black 7984 is also biodegradable, which makes it environmentally friendly.Formula:C26H15N5Na4O12S4Purity:Min. 95%Molecular weight:809.7 g/mol
