Method of Synthesis or Extraction
Eriochrome Blue Black B can be synthesized by the diazotization of 4-amino-5-hydroxy-2,7-naphthalenedisulfonic acid (H acid) followed by coupling with 2,2'-dihydroxy-1,1'-binaphthyl-3,3'-disulfonic acid (H2BINAP). The yield of this method is around 70%, and the process is relatively safe and environmentally friendly. Another method involves the reaction of H acid with 2,2'-dihydroxy-1,1'-binaphthyl-3,3'-disulfonic acid anhydride (H2BINAP-A) in the presence of sodium hydroxide. This method has a higher yield of around 90%, but it requires the use of toxic and hazardous chemicals. The extraction of Eriochrome Blue Black B from wastewater can be achieved by adsorption onto activated carbon or by coagulation-flocculation using aluminum sulfate or ferric chloride. These methods are effective in removing Eriochrome Blue Black B from wastewater, but they can also generate sludge and require proper disposal.
Chemical Structure and Biological Activity
Eriochrome Blue Black B has a molecular formula of C32H22N6Na2O6S2 and a molecular weight of 734.67 g/mol. Its chemical structure consists of two naphthalene rings linked by a diazo group (-N=N-) and two sulfonic acid groups (-SO3H) attached to the naphthalene rings. Eriochrome Blue Black B has been shown to exhibit antioxidant and antimicrobial activities. Its mechanism of action involves the scavenging of free radicals and the inhibition of bacterial growth. Eriochrome Blue Black B has also been studied for its potential use as a photosensitizer in photodynamic therapy for cancer treatment.
Biological Effects
Eriochrome Blue Black B has been shown to affect cell function and signal transduction pathways. It has been reported to induce apoptosis (programmed cell death) in cancer cells by activating the caspase cascade. However, Eriochrome Blue Black B can also have toxic effects on normal cells, particularly at high concentrations. Its potential therapeutic and toxic effects need to be further studied and evaluated.
Future Perspectives and Challenges
