Abstract

The dye auramine, used in textile and paper factory, is possibly carcinogenic according to Internation Agency for Research on Cancer (IARC). Its production and commercialization are forbidden in Europe, however, it still being sold and produced in another countries, even Brazil. Then, this work is proposed validate an method for analysis of auramine in surface water samples using LLE and HPLC-DAD-UV.

Highlights

Dyes may be classified as emerging contaminants, a group of potentially harmful compounds whose effects on the environment are poorly understood and their levels of use and contamination are increasing.[1]
There are no data on the use of this compound in Brazil, but several studies have been carried out and their presence in the hydrosphere has been found.[3]. This project aimed to validate the method of quantification of auramine in river water samples using LLE and HPLC- DAD-UV
The data in Chart 1 indicate the method is suitable for the analysis of auramine, which can be used to determinate the risk assessment, considering the LOQ obtained is lower than the PNEC value of 1.2 μg / L, stipulated to auramine. 3

Summary

Introduction

Dyes may be classified as emerging contaminants, a group of potentially harmful compounds whose effects on the environment are poorly understood and their levels of use and contamination are increasing.[1]. Dyes may be classified as emerging contaminants, a group of potentially harmful compounds whose effects on the environment are poorly understood and their levels of use and contamination are increasing.[1] Auramine dye is used in dyeing fabrics and paper factories, and as a component in paints. The production of this dye is banned in the US and Europe due to carcinogenicity, and is producing in India and China.[2] There are no data on the use of this compound in Brazil, but several studies have been carried out and their presence in the hydrosphere has been found.[3] this project aimed to validate the method of quantification of auramine in river water samples using LLE and HPLC- DAD-UV.
