Sodium 2′,4′,5′,7′-tetraiodo-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-3′,6′-bis(olate) (cas: 16423-68-0) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. Benzofurans are stable towards alkali and readily polymerize on treatment with sulfuric acid, due to which they are useful for the preparation of low cost chemically relatively inert resins.Application of 16423-68-0

Removal of erythrosine B using Prosopisspicigera L. wood carbon-iron oxide composite was written by Ramalakshmi, R. Dhana;Murugan, M.;Jeyabal, V.. And the article was included in Indian Journal of Chemical Technology in 2022.Application of 16423-68-0 This article mentions the following:

The present study investigates the removal of Erythrosine B (EB), a neurotoxin and carcinogenic dye from aqueous system using Prosopisspicigera L. wood (PsLw) carbon-iron oxide composite. The adsorbent is well characterized by Fourier Transform Infra Red spectroscopy (FTIR), Scanning Electron Microscope (SEM) for surface morphol., Brunauer-Emmett-Teller nitrogen adsorption method (BET)/methylene blue method for surface area determination and potentiometric methods for surface charge (pHzpc) determination The removal capacity of the adsorbent has been evaluated by batch method under varying pH, contact time, adsorbate initial concentrations, and in the presence of other ions. The Langmuir maximum adsorption capacity is found to be 487.8 mg/g at pH = 2.0 for an initial concentration of 250 mg/L. The adsorption follows pseudo second order kinetics and fits to Langmuir isotherm. The adsorption is thermodynamically spontaneous and exothermic in nature. Pore diffusion and mass transfer studies are performed. Column mode anal. is applied in the process for industrial applications. In the experiment, the researchers used many compounds, for example, Sodium 2′,4′,5′,7′-tetraiodo-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-3′,6′-bis(olate) (cas: 16423-68-0Application of 16423-68-0).
