HC Yellow No. 5 is a direct hair dye. Hair dyes containing HC Yellow No. 5, as "coal tar" hair dye products, are exempt from the principal adulteration provision and from the color additive provision of the Federal Food, Drug, and Cosmetic Act of 1938 when the label bears a caution statement and "patch test" instructions for determining whether the product causes skin irritation. Preliminary te...

Currently, the reduction of reactive dyes present in the textile effluent is a big challenge due to the threat to the environment. Existing physical and chemical methods contains many drawbacks. In the present scenario microbial reduction pays much attention and current focus of research. Therefore, the present study isolated dye decolorizing bacterium Exiguiobacterium aurantiacum (TSL7) from a...

The present work deals with the ways of testing the compatibility of reactive dyes with cotton in different textile industries in Bangladesh. This report includes three laboratory trials that were carried out for three different reactive dyes to check the compatibility for use in a dye recipe on cotton knitted goods. In this study, Spectrophotometric analysis was conducted and the fixation of e...

Abstract The purpose of this research is to report a unique manipulation producing carbon nanotubes/carbon xerogel (CNTs/CX) hybrid loaded with bimetallic catalysts Fe–Ni via one-step chemical vapor deposition (CVD) camphor. Active were formed during carbonization resorcinol–formaldehyde at 800 °C form (CX); meanwhile, the gas was librated from camphor 220 for 45 min. CX and CNTs/CX samples ana...

The umu test system is a newly developed method to evaluate genotoxicities of a wide variety of environmental carcinogens and mutagens (Oda et al., 1985; Nakamura et al., 1987). In the present study, SOS-inducing activity of 142 synthetic dyes was investigated by the umu test using Salmonella typhimurium (TA1535/pSK1002) under the condition of absence and presence of rat liver microsomal fracti...

In this research modified Kaolin by Cetyltrimethylammonium bromide is used as an adsorbent for the removal of Reactive Blue 21 from aqueous solutions. Response Surface Methodology was used to study the effect of independent variables, such as Reactive Blue 21 dye concentration (20, 40, 60, 80 and 100 mg/L), time (10, 20, 30, 40 and 50), initial pH (2, 4, 6, 8 and 10) and modified Kaolin dosage ...

The decolorization of reactive yellow 145 from wastewater in batch mode operation using groundnut shell-based biochar was studied the present research. adsorption process by investigating effects different variables such as temperature, initial dye concentration, pH, and dosage. results showed that dosage had a substantial impact on absorption potential. equilibrium determined to be 1 g/L, with...
