Acid-base indicator properties of dyes from local plants I: Dyes from Basella alba (Indian spinach) and Hibiscus sabdariffa (Zobo)
The acid-base indicator properties of aqueous and ethanol extracts from calyces of H. sabdariffa (Zobo) and a dye obtained from the ripe fruits of Basella alba (Indian spinach), two local plants, were investigated. A purple coloured dye obtained from the ripe fruits of Basella alba showed a λmax at 580nm, absorptivity of 0.2269 and was found to be photochemically unstable. A deep red coloured d...
متن کاملDyeing Properties Using Natural Dyes from Rhubarb:
In this investigation dyeing of alginate fiber was carried out after cationic treatment of 11 EPTAC (2, 3-Epoxypropyl Trimethyl Ammonium Chloride). Optimum dyeing process and 12 parameter show good dyeing performance when alginate fiber dyed with rhubarb dye. In addition 13 to cationic treatment is taken into account for alginate fiber to improve fastness, color strength, 14 breaking strength. ...

T h i s chapter describes the des ign, f a b r i c a t i o n , a n d propert ies of mater ia ls that respond to the presence of a chemical species by a change i n their opt ical properties. Ideally, such effects are reversible. They may be detected by conventional methods of absorpt ion, reflection, or luminescence spectrometry, a n d appl ied i n various formats such as test strips and disposa...
متن کاملAcid Dyes Removal from textile wastewater using waste cotton activated carbon: Kinetic, isotherm, and thermodynamic studies
The present study aims at investigating the potential of activated carbon AC prepared from waste cotton fiber for the removal of Acid Dyes from aqueous solutions. The prepared activated carbon was characterized by pore structure analysis, Fourier transforms infrared spectroscopy FTIR. Batch adsorption studies were carried out and the effect of experimental parameters such as pH, initial dye con...
