The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Treatment of the Allura Red food colorant contaminated water by a novel cyanobacterium Desertifilum tharense》. Authors are Gul, Ulkuye Dudu; Senol, Zeynep Mine; Tasstan, Burcu Ertit.The article about the compound:Sodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl)naphthalene-2-sulfonatecas:25956-17-6,SMILESS:O=S(C1=CC=C2C(/N=N/C3=CC(C)=C(S(=O)([O-])=O)C=C3OC)=C(O)C=CC2=C1)([O-])=O.[Na+].[Na+]).Synthetic Route of C18H14N2Na2O8S2. Through the article, more information about this compound (cas:25956-17-6) is conveyed.
The biosorption properties of a newly isolated and identified cyanobacterium called Desertifilum tharense were investigated in the current study. Following morphol. and mol. identification (16S rRNA sequencing anal.), the food colorant removal potential of this new isolate was determined Moreover, the isotherm, kinetic, and thermodn. studies were performed, and also the biosorbent characterization was studied after and before colorant biosorption with Fourier transform IR and SEM anal. Addnl., the changes in chlorophyll content of the biosorbent were examined after and before colorant treatment. The newly isolated cyanobacterial biosorbent removed 97% of Allura Red food colorant/dye at 1,500 mg L-1 initial dye concentration successfully at optimal conditions. Langmuir isotherm and pseudo-second-order kinetic models were fitted with the biosorption of the dye. The D-R model showed that the biosorption process occurred phys. The chlorophyll-a content of the biosorbent was neg. affected by the biosorption. The newly isolated and identified cyanobacterium seems to be a successful candidate for use to treat highly dye concentrated wastewaters.
《Treatment of the Allura Red food colorant contaminated water by a novel cyanobacterium Desertifilum tharense》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(Sodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl)naphthalene-2-sulfonate)Synthetic Route of C18H14N2Na2O8S2.
