Results Materials and Methods Four commercial dyes were used — Remazol® Black BA, Levafix® Blue Ca, Levafix® Yellow CA and Levafix® Red CA (Dystar). A standard anthraquinone dye, Remazol Brilliant Blue R (RBBR, Sigma) was also used. Dye stock solutions were added to solid or liquid decolorization media, up to 200 mg.L-1 final concentration. Rose Bengal Agar and Potato Dextrose Agar (both from D...

This paper reviews results obtained using statistical state dynamics (SSD) that demonstrate the benefits of adopting this perspective for understanding turbulence in wall-bounded shear flows. The SSD approach used in this work employs a second-order closure that retains only the interaction between the streamwise mean flow and the streamwise mean perturbation covariance. This closure restricts ...

Abstract The aim of this work was a complete thermodynamic study on the partitioning Remazol Yellow l, Brilliant Blue, and Red dyes in isopropyl alcohol + sodium phosphate water aqueous two‐phase systems at different temperatures. free energy change transfer, enthalpy entropy transfer were evaluated. effects structure dye, tie line length, temperature studied. results indicate that these have h...

In this research, fabrication and functionalization of MnO2 nanoparticles with cetyltrimethylammonium bromide (MnO2 NPs-CTAB) were confirmed for removal two reactive anionic sulfonated azo dyes: remazol red (RR) black 5 (RB5). The modified nanosorbent was characterized via X-ray diffraction, thermogravimetric analysis, Fourier transform infrared spectroscopy, BET SEM HRTEM studies. Various adju...

Of the five species of white rot fungi evaluated for their ability to decolorize Amaranth, Remazol Black B, Remazol Orange, Remazol Brilliant Blue, Reactive Blue, and Tropaeolin O in agar plates, Bjerkandera sp. BOS55, Phanerochaete chrysosporium, and Trametes versicolor displayed the greatest extent of decoloration. In static aqueous culture, the three cultures formed fungal mats which did not...

Di Indonesia, industri tekstil dan produk adalah salah satu penyumbang terbesar dalam peningkatan perekonomian. Namun perkembangan yang pesat ini berbanding terbalik dengan keseimbangan lingkungan hidup. Salah menjadi masalah utama dari limbah cair dihasilkan yaitu berupa zat warna. Umumnya dibuang termasuk senyawa organik tidak dapat diuraikan oleh mikroorganisme cepat sehingga menyebabkan pol...

This study investigates the adsorption behavior of Reactive Black 5 (RB) and Reactive Yellow 176 (RY) from aqueous solution on coal fly ash (FA-CO), HCl-treated coal fly ash (TFA-HCl), and biomass fly ash (FA-BM). In preliminary study, the FA-BM showed the greatest dye adsorption capacity of both dyes, compared to FA-CO and TFA-HCl. Hence only for the FA-BM, the effects of various experiment pa...
