Biosorption is becoming a promising alternative to replace or supplement the present dye removal processes from dye wastewaters. Based on the results of batch studies on biosorption of the dyes on powdered fungal biomass, Aspergillus niger, an immobilised fungal biomass was used in column studies for removal of four dyes, Acid Blue 29, Basic Blue 9, Congo Red and Disperse Red 1 from aqueous sol...

Mesoporous photocatalysts of CeO2/SBA-15 are prepared by two methods of direct synthesis as solvent-usage and solvent-free methods. In solvent-usage method, CeO2/SBA-15 is synthesized in acidic media. While, in solvent-free method, CeO2/SBA-15, has been prepared through the novel path of directly grind cerium salt into the as-prepared samples of SBA-15 occluded ...

BACKGROUND Primary localized cutaneous amyloidosis (PCA) is a relatively rare condition characterized by amyloid deposition in dermis without systemic involvement. Although, histopathological examination of the lesion reveals amorphous eosinophilic deposits in papillary dermis examination of congo red stained slides under polarized light will give definitive diagnosis AIMS To study the clinic...

The powder of Ocimum tenuiflorum leaves (OtLP) was modified by ZnCl2, H2C2O4, or CuS. powders were characterized and applied as adsorbents for the first time to adsorb Congo red (CR). effects most potent experimental variables on CR adsorption chosen adsorbent examined. Kinetic, isotherm, thermodynamic constants investigated. best discovered be ZnCl2 CuS, which removed 97.82% had a pore size 13...

Abstract Metal–organic frameworks (Sm-MOFs) were prepared using a microwave-assisted ball milling method with water solution. The structure was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and SEM, the thermal stability of Sm-MOFs tested Thermogravimetry (TGA). results showed that Sm-MOF material exhibited favorable effect on removing organic dye Con...

In this work, the ability of the MgCaFe- Layered double hydroxide (LDH) for congo red (CR) dye removal in aqueous solution was investigated. Various parameters such as initial dye concentrations, temperature, adsorbent dosage, pH effect and agitation rate were examined and optimal conditions (10 mgL-1 of the dye concentration, 25 °C of temperature, 0.5 gL-1 of the adsorbent dosage, pH~7 and 450...

The interaction of Congo Red CR with a series of Alkyltrimethylamoniumbromide CnTAB, N-hexadecylpyridinium bromide CPB and N-hexadecylpyridinium CPC were investigated using conductometry technique. It was observed that the formation of dye-surfactant ion pairs takes place at surfactant concentration far below the critical micelle concentration of the individual surfactants. Aggregation was refl...

Nickel oxide (NiO) nanoflowers are synthesized via a one-pot method using an amphiphilic block copolymer in aqueous solution. Pluronics F-127 works as structure-directing agent the formation of NiO nanoflowers. The controlled hydrolysis precipitating slowly releases ammonia that can form Ni(OH)2, which is stabilized polymer calcination removes polymeric part nanocomposite and converts Ni(OH)2 i...

The coal tar-based carbon with ultra-high specific surface area was synthesized from tar using CaO as template coupled KOH activation by conventional heating. To utilize the existing pores of porous carbon, multilayer adsorption organic dyes, including Congo red and methylene blue, tested. Results show that as-made features hierarchical structure, which is containing both micropores abundant me...
