Resumen
Descripción
Many laboratories of chromatographic analysis use different solvents as acetonitrile, hexane, chloroform, etc. which generate high quantities of residues during the analyses or by storing solvents out of validity. In both cases, such waste must be disposed safely to avoid environmental contamination. In this study some methodologies were developed for treatment and recovery of acetonitrile, hexane and chloroform in few steps and with low consumption of reagents. All solvents were obtained in high yields and with adequate purity for application in separations by column chromatography and HPLC.
