in this study, aniline-formaldehyde polymer was synthesized and then modified with extra aniline as cross-linker in the presence and absence of ni(ii) as the template to produce ion imprinted poly(aniline-formaldehyde) (iipaf) and non imprinted poly(aniline-formaldehyde)(nipaf) the iipaf was subjected to adsorption, preconcentration and determination of ni(ii) ion in environmental samples. the ...

equilibrium adsorption property of multi-walled carbon nanotubes with oh group was studied using experimental design for the adsorption of co2 , ch4 and h2 . the effect of temperature, pressure, their binary interactions and quadratic terms were studied for adsorption capacity of nanotubes and the results were analyzed by the face centered central composite design method and analysis of varianc...

Unmodified zeolites show little affinity for anions due to the fact that their surfaces are negatively charged. However modification of zeolites with amines turns their negative surface charge to positive and creating higher adsorption capacity for anions. In this study, polyaniline-clinoptilolite composite was prepared by polymerization of anilinium on the surface of zeolite. The composite...

ADSORPTION OF COPPER(II) BY PEANUT HULLS IN A FIXED-BED, CONTINUOUS FLOW COLUMN Tyler Stephen Cook, Masters of Science in Chemistry Western Carolina University (April 2017) Advisor: Dr. Carmen L. Huffman Heavy metal pollution is an important concern due to its adverse health and environmental effects. Biosorption is a way to remove heavy metals from aqueous systems with the use of biomaterials....

interaction of pb(ii) ion with modified banana shell (mbs) and banana shell (bs) during adsorption fromaqueous solution were investigated. batch experiments were carried out to investigate the effect of contact time,ph, and idmid ion concentration on adsorption efficiency. the favorable pll for maxim= pb(ii) adsorptionwas at 5.0. for the investigated imoi) concentrations (10-80 mph), maximum ad...

Aqueous-phase edsorption equilibrium and kinetic mechanism of phenol, 3-chlorophenol rnd o-cresol onto Norit Granular Activaied Caibon (NAC 1240) were studied in a batch system at temperature of 30 oC, agitation speed of 120 rpm, initial phenol concentrations of 25-200 mg/t. The elfects of initid phenol concentration and time of adsorption on phenol adsorption process were lnvestigated. The ads...

Oxygen-enriched carbon materials derived from carbon dioxide were functionalized using sulfonic acid to remove Sr ions from aqueous solutions. Synthesized sulfonated porous carbon materials (PC-SO3H) showed higher adsorption capacity and selectivity towards Sr than non-functionalized porous carbons (PC). The formation of the C-SO3H functional group in PC-SO3H and its ability to proton exchange ...

The aim of this study was to evaluate the adsorption capacity of the novel coated activated carbon by chitosan for removal of Cr (VI) and Cd (II) ions from single and bi-solute dilute aqueous solutions. In addition, the adsorption abilities of activated carbon (AC), chitosan (CH) and chitosan / activated carbon composite (CHAC) have been compared. Adsorption studies were performed in a batch sy...

The performance of activated sludge in the removal of tetradecyl benzyl dimethyl ammonium chloride (C14BDMA) by adsorption from aqueous solution was investigated with different PH, contact time, ionic strength and temperature. Equilibrium was achieved within 2 h of contact time. The adsorption capacity increased largely with increasing solution pH and remained constant above pH 9. The ionic str...
