The adsorptions of reactive procion brilliant red H-EGXL and procion yellow H-EXL by various clay adsorbents were investigated in this research. The research showed that synthetic talc has the highest adsorption capacity for decolorization of both procion type of reactive dyes compared with other clay adsorbents. The removal efficiencies of synthetic talc relatively stable above 80% until the i...

The study aim was to test the applicability of exoskeletons and molts from mealworm (Tenebrio molitor) cultures as sorbents for anionic dyes: Reactive Black 5 (RB5) Yellow (RY84). Factors investigated included: characteristics (FTIR, pHPZC), influence pH on sorption efficiency, kinetics (pseudo-first, pseudo-second-order, intraparticle diffusion models), determination maximum capacity (Langmuir...

The extracellular colorants produced by Chlorociboria aeruginosa, Scytalidium cuboideum, and Scytalidium ganodermophthorum, three commonly utilized spalting fungi, were tested against a standard woodworker's aniline dye to determine if the fungal colorants could be utilized in an effort to find a naturally occurring replacement for the synthetic dye. Fungal colorants were delivered in two metho...

Explant cultures were established from capsule/epithelium preparations from both normal and cataractous lenses to investigate properties of human lens epithelial cells. The cultured cells were found to have similar membrane potentials to whole human lenses and isolated epithelia, and similar free ionic concentrations of potassium, sodium, and calcium (131 mM, 17 mM and 0.8 microM respectively) ...

We characterized gap junctional communication in the extraembryonic tissues of the 7.5-d gastrulating mouse embryo. At this stage of development, the extraembryonic tissues form a large part of the conceptus, and link the embryo proper to the maternal tissue. Using Lucifer yellow injections, cells in most extraembryonic tissues were observed to be very well dye coupled, the only exception being...

We report an environmentally friendly synthetic strategy to fabricate reduced graphene oxide (rGO)-based ternary nanocomposites, in which glutathione (GSH) acts both as a reducing agent for graphene oxide and sulfur donor for CdS synthesis under modified hydrothermal (MHT) conditions. The report becomes interesting as pH variation evolves two distinctly different semiconducting nanocrystals of ...

This study was aimed to investigate the amount of reactive blue 29 (RB29) dye removal from aqueous solution by Chitosan extracted from Persian Gulf shrimp shell. The effect of parameters such as pH, the concentration of reactive blue 29 dye, contact time, and adsorbent dosage in dye removal was studied. Isotherm, Thermodynamics, and kinetics of adsorption process were also investigated. The...

introduction: discharge of textile wastewater causes the reduction of sunlight penetration, interferes with the receiving waters ecology and damage the environment. the aim of this study was to determine the removal efficiency of reactive blue 19 dye from aqueous solutions by cuttlefish bone powder. materials & methods: this study was performed experimentally and in laboratory scale. in this re...

This study aimed to optimize the preparation condition of activated carbon using Teff straw as a precursor material via evaluating its potential in terms maximizing adsorptive removal Reactive Yellow 145 dye (RY 145) from aqueous solutions. Selective factors, such activation time, temperature, and impregnation ratio on Straw-based Activated Carbon (TSAC) were optimized response surface methodol...
