expanded graphite nanosheets (eg-nanosheets) were used for adsorption of malachite green (mg) from aqueous solution. the influences of dye concentrations, absorbent dosage, ph values and the temperatures on the adsorption were investigated as well. the dye adsorption experiments were carried out by utilizing batch procedure. eg-nanosheets were initially characterized by scanning electron micros...

Abstract: Metal organic framework (MOF) of MIL-101(Cr)-Silica (SiO₂) composites with highly mesoporous and uniform dispersions were synthesized by a microwave-assisted hydrothermal method followed by the sol-gel technique. Water vapor adsorption experiments were conducted on the MIL-101(Cr)-SiO₂ composites for industrial adsorption chiller applications. The effects of MIL-101(Cr)-SiO₂ mixing ra...

The plant powder of Jaswand (Hibiscus rosa-Sinensis) were activated with sulphuric acid and used as low cost easily available and renewable biological adsorbent for the removal of acid dyes (acid blue, acid red and malachite green) from aqueous solution. Batch experiments were carried out for adsorption kinetics and isotherms. Operating variable studied were pH, temperature, adsorbent dose, ini...

High concentration animal wastewater is often contaminated by tetracycline and an upflow anaerobic sludge bioreactor (UASB) with granular sludge is often used to treat the wastewater. The investigation of the adsorption process of tetracycline on anaerobic granular sludge during anaerobic digestion of animal wastewater will increase the understanding of antibiotics behavior in the UASB reactor....

In this study, a series of laboratory tests were conducted to investigate the efficiency of hydroxyapatite (1-iAP)nanopowders towards adsorption of lysozyme from aqueous solution. In the present research. I RP nanopowderssynthesized from egg-shell characterized using SEM and FT-Ht. The adsorption of lysozyme was I mg/mL using0.1 g adsorbent in 100 mL of lysozyme solution. Adsorption data were f...

existence of acid humic in water resources is undesirable and causes carcinogenic component in disinfection process due to reaction with chlorine. due to their cost-effectiveness and higher physical resistance than activated carbon, natural zeloites are used for removing various pollutants. . in the present study, iranian natural zeolite modified with cetylpyridinium bromide (cpb) was investiga...

The studies on removal of Lead (II) were conducted using Coconut shell. Adsorption efficiency has been evaluated. The effect of pH, contact time, adsorbent dose, concentration of metal, particle size and temperature were studied. The result reveals that Langmuir and Freundlich isotherms are followed during adsorption process. Thermodynamics parameter indicates the feasibility of the process. Ki...

The adsorption parameter, A,, (maximum protein adsorbed/g substrate) and KA (adsorption equilibrium constant) of Trichoderma reesei C-5 cellulases were 58.8 mg protein/g cellulose and 11.6 x 104 Z/m01 respectively. The activation energies for the adsorption rate constants of cellobiobydrolases and endoglucanases of C-5 were 30% and 11% lower respectively than that in the parent T. reesei QM9414...
