Application of spectroscopy in the process of obtaining dyes from onion pell

Abstract

A dye-receiving technology from waste products in the form of onion peel. Spectroscopic methods defined temperature extraction mode pigments. It is shown that bioflavony and extracts from onion peels tend to form complexes with metal ions. It was found that the reaction of complexation with the metal ion of quercetin are characterized by the formation of connection with metal by electron transfer from the metal d orbitals in the π * orbital of quercetin. The Study of the natural scales dye staffs pommel and cortex of the plants ruyan applicable in textile industry. The Determination main dying pigment of the dye staffs and offers of the methods to stabilizations of the dye staff.
