Bottom ash, a waste of thermal power plants, and deoiled soya, an agricultural waste material, were employed for successful removal and recovery of hazardous phenol red dye from wastewaters. The adsorption characteristics and operational parameters were determined by monitoring different parameters such as effect of pH, effect of concentration of the dye, amount of adsorbents, contact time, and...

The plausible role of arginine and tyrosine residues at the active side of horseradish peroxidase (HRP) in aromatic donor (guaiacol) oxidation was probed by chemical modification followed by characterization of the modified enzyme. The arginine-specific reagents phenylglyoxal (PGO), 2,3-butanedione and 1,2-cyclohexanedione all inactivated the enzyme, following pseudo-first-order kinetics with s...

ABSTRACT. Iodinated heterocyclic molecules are crucial structural components of many natural products, including hormones, vitamins, and medicines. The pharmaceutical survey is very interested in the investigation kinetics iodination N-(p-chlorophenyl)-3,5-dimethyl-1,1-dioxo-1,2-thiazine. rate directly dependent on concentration both 1,2-thiazine iodine under different molar ratios (1:10), (10:...

The adsorption of Triton X-100 in aqueous solution on the granite sand has been investigated to evaluate its ability as an adsorbent. Various parameters such as agitation time, adsorbent dose, adsorbent size, initial concentration of adsorbate, pH, temperature, and effect of interference ions were studied on the laboratory scale to establish optimum conditions for the removal of TX-100 from the...

In the present study, adsorption behavior of sulfadiazine (SDZ) on various sediments under different hydrodynamic conditions generated by a rocking shaker was investigated. Based dye mixing experiments, three regimes with characteristics, i.e., laminar, transition, and turbulent regimes, were identified. The intensity found to have positive effect SDZ, general, capacity followed order > tran...

background and purpose:the presence of dyes in wastewaters may cause serious problems for the environment because of their high toxicity to aquatic organisms and unfavorable aesthetical impact. in the present study, multi-walled carbon nanotubes (mwcnts) were used for removal of anionic dyes direct blue 106 (db106) and acid green 25 (ag25), from water samples. materials and methods:mwcnts were ...

This study reports the first approach of immobilizing a redox (glucose oxidase-GOx) enzyme on amino functional group-integrated tailor-made textile (polyester nonwoven fabric-PF) support matrix. To achieve that, polyethylenimine if not chitosan was chemically grafted plasma (with O2/N2 gas)-activated PF before GOx through physical adsorption. Diverse qualitative and quantitative characterizatio...

Cauliflower leaf powder (CLP), a biosorbent prepared from seasonal agricultural crop waste material, has been employed as a prospective adsorbent for the removal of a basic dye, methylene blue (MB) from aqueous solution by the batch adsorption method under varying conditions, namely, initial dye concentration, adsorbent dose, solution pH, and temperature. Characterization of the material by FTI...

Fresh water source scarcity in arid and semiarid area is limitation factor for saline-sodic soil reclamation. The reusing of agricultural drainage and industrial wastewater are preferred strategies for combating with this concern. The objective of current study was evaluation in application of industrial sugar manufacture wastewater due to high soluble organic compounds in saline-sodic and sodi...

The ability of orange peels (OP) and almond peels (AP) as adsorbents for the removal of a dyestuff, namely methylene blue (MB) from aqueous solutions has been studied. After their characterization by different techniques (elemental analysis, biochemical analysis, IR spectroscopy, thermogravimetric analysis, scanning electron microscopy, mercury porosimetry), adsorption kinetics of the dye have ...
