The nonylphenol (NP) biosorption and desorption potential for fungal biomass used under batch conditions was investigated using kinetics and isotherm models. Fungal biomass of Rhizopus arrhizus TISTR 3610 exhibited preferential uptake of NP, an endocrine disrupting chemicals. Sporangiospores, asexual spores, were immobilised in chitosan beads. The biosorption data of NP on the moist heat inacti...

methyl orange is one dye resulted from the textile industry. the aim of this study is to test theadsorption capacity of nickel oxide nanoparticles for removing the methyl orange from aqueoussolution. the parameters studied were the effect of temperature, contact time and initial ph ofsolution. results indicate that the removal efficiency of nickel oxide nanoparticles increases withincreasing co...

Hydrothermal and non-hydrothermal spherical TiO2 nanoporous with crystalline framework were prepared by sol-gel method. The Crystalline structures, morphologies and surface texturing of materials were determined by X-ray diffraction (XRD), scanning electron microscopy (SEM) and N2 adsorption-desorption isotherms. The Hydrothermal spherical TiO2 nanoporous was found to have a narrow and strong p...

We report results of nitrogen and argon adsorption experiments performed at 77.4 and 87.3 K on novel micro/mesoporous silica materials with morphologically different networks of mesopores embedded into microporous matrixes: SE3030 silica with worm-like cylindrical channels of mode diameter of approximately 95 angstroms, KLE silica with cage-like spheroidal pores of ca. 140 angstroms, KLE/IL sil...

To evaluate atrazine behavior in an agricultural soil (adsorption–desorption, leaching) and the effects of bioaugmentation with Arthrobacter sp. strain AAC22, as a remediating strategy. An history application was used. Equilibrium batch experiments allowed investigation adsorption–desorption at different depths, while leaching potential assessed using disturbed columns. AAC22 selected for bioau...

volumetric techniques were employed to study the adsorption of co2 on a purified multi-wall carbon nanotubes (mwnt’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 k and pressures ranging from 30 to 150 kpa. langmuir, freundlich and sips equations were used to represent the isotherms. also the parameters of these fitted isotherm models have been determined. the ...

The idea of generating high-value practical materials, such as activated carbons, from agricultural wastes a raw material has been quite important trend recently due to its positive contributions the environment and resource savings biomass. In this paper, carbons prepared durian husk waste by KOH chemical activation method are studied. We focus on effects stages activating temperature their pr...

water desorption isotherms of raw and osmotically dehydrated (at 25ºc, for 2 hours, with 10 and 26% nacl solutions) garlic slices at different temperatures (25, 40, 55, and 70ºc) were experimentally determined over a range of water activity of 0.05–0.90 using a static gravimetric method. desorption isotherms can be classified as type iii. the water desorption isotherms of raw garlic clearly sho...

Cow bone charcoal (CBC) was synthesized and used for the removal of metals ions (manganese, iron, nickel and copper) from aqueous solutions. Two different adsorption models were used for analyzing the data. Adsorption capacities were determined: copper ions exhibit the greatest adsorption on cow bone charcoal because of their size and pH conditions. Adsorption capacity varies as a function of p...

Conventional separation methods are not suitable for recovering palladium present in low concentrations in ore leaching solutions. In this study, a novel isopentyl sulfide (S201)-impregnated α-MnO₂ nanorod adsorbent (BISIN) was prepared, characterized, and applied for the selective adsorption and separation of palladium from the leaching liquor of ores. Batch studies were carried out, and the m...
