Specifically this research involves selection of alternate less toxic and greener organic solvent for use in a methyl orange method for colorimetric determination of cationic surfactants in the 0.2 to 2.0 mg/L range. The principles, steps and management of the methyl orange method include: (a) complexation of cationic surfactant with methyl orange at acidic pH condition forming a methyl orange-surfactant complex; (b) organic solvent extraction; (c) water-solvent phase separation; (d) spectrophotometric measurement and (e) good laboratory practice and laboratory hazardous waste management.
