In this report, a detailed analysis on the calculation of extractability of SDBS and DOC has been made from the optical absorption spectroscopy using Beer-Lambert law. The extinction coefficient,2.0922±0.02545 mL/mg.mm for SDBS, was used to calculate the concentration of SWCNTs in the suspension after dispersion for various surfactant concentrations. UV-vis-NIR spectra of aqueous SWCNTs-surfactant mixture of varying surfactants concentration, and SWCNTs-organic solvent mixture are provided in this supporting information. These absorption spectra were used to determine the optimum dispersion condition.
