Effects of surface functional groups and porous structures on selective adsorption mechanisms of pharmaceutical residues on organic-inorganic hybrid adsorbents
1) To investigate the effects of surface functional groups, pore size, crystalline structures, hydrophobicity and surface area on adsorption/desorption capacities and mechanism of adsorption of pharmaceutical residues (i.e. hormones, antibiotics, antilipicdemics, and non-steroidal anti-inflammatory drugs) onto functionalized porous and/or superparamagnetic porous silicates.
2) To evaluated effects of molecular characteristics of pharmaceutical residues on interaction with both NOM and organic-inorganic hybrid adsorbents.
3) To investigate the effects of pH and temperature on adsorption capacities and mechanism of adsorption of the pharmaceutical residues onto organic-inorganic hybrid adsorbents.
4) To determine the adsorption selectivity of difference pharmaceutical residues on organic-inorganic hybrid adsorbents.
