Bioaccumulation of synthetic dyes viz. Acid Blue 93, Direct Red 28 and Basic Violet 3 by the environmental yeast isolate, Candida tropicalis growing in aqueous extract of sugarcane bagasse medium was studied in a batch system as a function of initial pH and dye concentrations. The optimum pH value for bioaccumulation was found to be 3.0 for Acid Blue 93 and Direct Red 28 and 5.0 for Basic Viole...

In this study, degradation of Basic Violet 16 (BV16) by ultraviolet radiation (UV), ultrasonic irradiation (US), UV/H2O2 and US/H2O2 processes was investigated in a laboratory-scale batch photoreactor equipped with a 55W immersed-type low-pressure mercury vapor lamp and a sonoreactor with high frequency (130kHz) plate type transducer at 100W of acoustic power. The effects of initial dye concent...

The effect of acid-alkaline treatment of lignocellulosic material (wild carob forest wastes) on Ethyl violet adsorption was investigated. It was found that surface chemistry plays an important role in Ethyl Violet (EV) adsorption. HCl treatment produces more active acidic surface groups such as carboxylic and lactone, resulting in an increase in the adsorption of EV dye. The adsorp...

In this study, the adsorption of certain water-soluble cationic dyes, (basic blue 9, basic blue 12, basic blue 17, brilliant cresyl blue, janus green B, basic green 4, basic violet 1, basic violet 3, and thionin) onto TriSyl silicas by batch adsorption at 25◦C was investigated. In the adsorption experiments, Langmuir type adsorption in the Giles classification system was found. Binding paramete...

The sorption of three basic dyes, named basic violet 10, basic violet 1, and basic green 4, from aqueous solutions onto sugarcane dust was studied. The results revealed the potential of sugarcane dust, a waste material, to be a low-cost sorbent. Equilibrium isotherms were analyzed using the Langmuir, the Freundlich, and the three-parameter Redlich-Peterson isotherms. In order to determine the b...

Fungi is widely found on air, soil, water and organic substances in nature. Unlike single-celled bacteria, fungi form multicellular structures, sometimes even visible to the naked eye. In studies of Aspergillus sp. removal dye order obtain information, examinations are made by painting. Basic dyes, when ionized, charged with positive electricity. dyes include malachite green, methyl violet, cry...

The adsorption of basic dye (i.e., ethyl violet or basic violet 4) from aqueous solution onto the regenerated spent bleaching earth (RSBE) was carried out by varying the process parameters such as initial concentration, pH, and temperature. As analytical comparisons, activated bleaching earth (ABE) was also used as adsorbent for the adsorption of the basic dye at various initial concentrations....

A novel discrete single-walled metal-organic nanotube (JLU-MONT1) with a rare armchair (3,3) carbon nanotube topology is successfully synthesized, which is further linked by hydrogen-bonds forming a 3D supramolecular architecture. Benefiting from its anionic skeletal features and open mesoporous channels (21 Å), JLU-MONT1 exhibits extremely high efficiency and capability to adsorb carcinogens b...
