Fixed-bed column adsorption performance for ammonia removal using adsorbent from zeolite

Erratum to: Adsorption performance of packed bed column for nitrate removal using PAN-oxime-nano Fe2O3

A continuous fixed bed study was carried out by using PAN-oxime-nano Fe2O3 as a sorbent for the removal of nitrate from aqueous solution. The effect of factors, such as flow rate (2, 5 and 7 mL/min) and bed depth (5, 10 and 15 cm) were studied. Data confirmed that the breakthrough curves were dependent on flow rate and bed depth. The adsoption capacities observed in diffent conditions of flow r...

Disinfection and removal performance for Escherichia coli and heavy metals by silver-modified zeolite in a fixed bed column

Experimental, Kinetics and Isotherm Modeling of Carbon Dioxide Adsorption with 13X Zeolite in a fixed bed column

In this work, zeolite 13X with porosity structure has been used as an adsorbent for adsorption of CO2 flue gas. The effect of operating conditions including pressure and time on adsorption capacity were investigated. The experiments conditions are constant temperature, the range of pressure 1 - 9 bar and the registration of adsorption capacity with passing of time. Experimental data were adjust...

kinetic modeling of heavy metals adsorption on fixed bed column

the adsorption of lead (11) and copper (11) in a fixed bed column using activated carbonprepared from nipa palm nut was investigated. thomas model and yoon and nelson kinetic models were used to analyze the column performance. the rate constant for thomas model increased with increase in flow rate and initial ion concentration but remained constant at varying bed height. adsorption capacity for...

Aqueous Cadmium Ions Removal by Adsorption on APTMS Grafted Mesoporous Silica MCM-41 in Batch and Fixed Bed Column Processes

Highly ordered mesoporous MCM-41silica with hexagonal structure was synthesized using extracted amorphous silica from sedge (Carex riparia) ash. Obtained mesoporous materials functionalized by 3-(Aminopropyl) trimethoxysilane (APTMS) and their structures characterized by means of X-ray diffraction (XRD), nitrogen adsorption-desorption, thermogravimetric analysis (TGA) and Fourier transform infr...
