Comparative Spectroscopic Studies on Flotation Rate of Low Toxic Mixed Solvents
Asian Journal of Chemistry(2019)
Abstract
The application of hydrophilic mixed solvents provides a new direction for the study of green air flotation technology. In this test, a mixture of n-propanol and anhydrous ethanol (4:1) was selected as solvent, sodium chloride as phase separator, sodium hydroxide solution was used to maintain acidity and hydrophobic associations formed by Fe(III) and doxycycline were flotated to the organic phase. After flotation, the hydrophobic associations were analyzed by spectrophotometry and high performance liquid chromatography. The results showed that the hydrophilic mixed solvent maintained good flotation rate without toxicity
