Abstract:This study shows the dyeing behaviour and impact over the wastewaters quality resulted from dyeing wool fibres, of a new synthesized premetalated dyes, derived from new acid dye, sodium(E)-2-((1-amino-4-sulphonatonaphthalen-2-yl)diazenyl)-6methoxybenzo[d]thiazole-5 or 7-sulphonate, as a result of interaction with Ni(II) and Zn(II) ions. In order to characterize the complexed dyes they were studied in both phase: solution and solid phase. The dyeing performances assessment and the environmental impact has been … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
