1. Twenty-eight leaf-protein concentrate (LPC) samples, subjected to different thermal treatments, were produced from five curd batches. For these samples, the fluorodinitrobenzene (FDNB)-reactive lysine values gave closer agreement with dye-binding lysine (DBL) than with the dye-binding capacity (DBC). 2. No relationship was established between the dye-bound-after-propionylation (DBAP) and the...
Background and Objective: PACT is an adsorption- degradation process through which slowly or non-biodegradable waste water compounds such as dye can be degraded. This study was carried out to evaluate the efficacy of PACT in removal of dyes form textile industry wastewaters. Materials and Methods: This research was carried out in pilot scale. The pilot design had two parts: an aeration tank wit...
Background and purpose: Colors are toxic organic materials with complex structures used in textile production stages such as dyeing, finishing and printing that cause environmental problems. One of the most widely used colorant in textile is reactive blue 19 dye. This study aimed to examine the feasibility of TiO2 as catalysts and sonochemistry process for discoloration of reactive blue 19 from...
Seven reactive dyes judiciously selected based on chemical structures and fixation mechanisms were applied at 2% of of shade on amidoximated acrylic fabrics. Amidoximated acrylic fabric has been obtained by a viable amidoximation process. The dyeability of these fabrics was evaluated with respect to the dye exhaustion, fixation, and colour strength under different conditions of temperature and ...
The present investigation assesses the application of ceric sulfate for the removal of the colorant reactive blue19 (R.B19) from synthetic wastewater. The adsorption characteristics and dye removal efficiency of adsorbent have been determined by investigating factors such as effect of pH (pHOptimum
In this work La0.7Sr0.3MnO3 , one group of nanosized perovskite-type oxides were prepared by sol-gel method. The perovskite structure has been characterized by X-ray diffraction (XRD) , scanning electron microscopy (SEM) , energy dispersive X-ray spectrometer (EDX) and Fourier transform infrared (FTIR) . The nanoparticles showed the excellent adsorption properties towards reactive blue 4 (RB4) ...
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...
In this study, the adsorption of Reactive blue 19 onto pomegranate residual-based activated carbon PRAC was investigated in aqueous solution. The activated carbon prepared by phosphoric acid activation under air condition. PRAC was characterized for its surface chemistry by point of zero charge measurements, Scanning Electron Microscopy and nitrogen adsorption at 77 K. The effect of operational...
