the mononuclear gd(iii) complex, [gd(l)3(h2o)5] (where l is alizarin yellow r (nac13h8n3o5)), has been prepared in h2o under reflux condition. the gd(iii) complex has been characterized by elemental analysis and spectroscopic methods (uv–vis and ft–ir). the gd2o3 nanoparticles were prepared by the calcination of the gd(iii) complex in air at different temperatures up to 600 °c for 2 h. the calc...

The Cyclic Voltammetry (CV) was used to investigate the electrochemical behavior of alizarin yellow R and some analogous arylazo compounds having almost the same central azo group. For this purpose, the substances chosen for the measurements are Alizarin Yellow R (AYR), Eriochrome Black T (EBT) and Sudan II (SUD II). The investigations were carried out at room temperature (298 K) in both aqueou...

In this study, we designed a membrane-free, continuous plug-flow baffled bioelectrocatalyzed reactor (PFB-BER) to enhance the degradation of azo dye containing wastewater. The efficiency of decolorizition of alizarin yellow R (AYR) was tested in such a bioelctrochemical system with acetate as carbon source. The influent containing AYR (100mg·L) and acetate (1000mg·L, 25mM PBS) was flowed into t...

In this study, two modes of hybrid anaerobic digestion (AD) bioreactor with built-in BESs (electrodes installed in liquid phase (R1) and sludge phase (R2)) were tested for identifying the effect of electrodes position on azo dye wastewater treatment. Alizarin yellow R (AYR) was used as a model dye. Decolorization efficiency of R1 was 90.41 ± 6.20% at influent loading rate of 800 g-AYR/ m(3)·d, ...

A multimode, dual functional nanomaterial, CNTs-Ag2S, comprised of carbon nanotubes (CNTs) and silver sulfide (Ag2S) nanoparticles, was prepared through the facile hydrothermal process. Before deposition Ag2S hydrophobic CNTs were modified to become hydrophilic refluxing with a mixture concentrated nitric sulfuric acids. The oxidized employed deposit nanoparticles for their efficient immobiliza...

L-Asparaginase enzyme has received great attention owing to its potential as anticancer drug and food processing agent. L-Asparaginase producing microbes are conventionally screened on phenol red plates containing L-asparagine as the sole nitrogen source for its growth. However, the contrast of the zone in phenol red plates is not very distinct. To overcome this problem, an alternate methodolog...
