Abstract Acetone is a solvent used in many laboratories and factories. Serious problems will occur when it exposed to the environment. Therefore, new design hydrophobicity bimetallic metal material (10-Fe 1 Mn -USY) was prepared for acetone adsorption under conditions of high humidity. Hydrophobic Y type zeolite prepare materials effect different operating parameters (including material, humidi...

The aim of the present work is to prepare an adsorption package to simulate adsorption / desorption operation for both single and multi-component systems in an isothermal condition by different mechanisms such as; local adsorption theory and mass transfer resistance (rigorous and approximated methods). Different mass transfer resistance mechanisms of pore, solid and bidispersed diffusion, t...

In this research, the generation process of engineered microsphere agarose adsorbent has been explained that has surfaces with different active sites to adsorb protein nanoparticles into the fluidized-bed system. Also, excellent selectivity of protein nanoparticles, high adsorption capacity, and fast equilibrium rate through the eco-friendly polymeric adsorbents were vital aims in here. Hence, ...

Understanding the dynamics of fixed-bed adsorption columns for modeling is a demanding task due to the strong nonlinearities in the equilibrium isotherms, interference effects of competition of solutes for adsorbent sites, mass transfer resistances between fluid phase and solid phase, and fluid-dynamic dispersion phenomena. The interplay of these effects produces steep concentration fronts, whi...

Contamination of drinking water due to fluoride is a severe health hazard problem. Excess of fluoride (>1.5mg/l) in drinking water is harmful to the human health. Various treatment technologies for removing fluoride from groundwater have been investigated in the past. Present investigation aims to remove fluoride by activated alumina. Adsorption isotherm has been modeled by Langmuir equation an...

The adsorption behaviors of treated animal bone (TAB) with methylene blue dye (MBD) were studied. The aim of this study is to remove MBD from wastewater. A synthetic solution of 25 mg/L of the dye was used. The adsorption process was affected by contact time, doses of adsorbent, concentration of dye and temperature. It was carried out at constant pH (7.1). The optimum contact time was 90 min an...

In recent years, the treatment of water pollution has been a challenging and far-reaching topic. order to improve adsorption performance polyvinyl alcohol nanofibers, new nano-adsorbent graphene oxide was introduced into them in this work. The resistance stability nanofibers were improved by crosslinking glutaraldehyde. introduction GO greatly increased Cu2+, methylene blue (MB) Congo red (CR)....

CO2 geosequestration is currently considered to be the most effective and economical method to dispose of artificial greenhouse gases. There are a large number of coal mines that will be scrapped, and some of them are located in deep formations in China. CO2 storage in abandoned coal mines will be a potential option for greenhouse gas disposal. However, CO2 trapping in deep coal pillars would i...

Batch adsorption studies were undertaken with the abundantly available waste biosorbent Tectona grandis L.f. leaf powder for removal of cadmium(II) from aqueous solutions. The adsorption experiments were performed under various conditions such as time, temperature, different initial Cd(II) concentrations, pH, adsorbent dosage, and adsorbent particle size. The data showed that in 30 minutes, 1 g...
