Description
This powerpoint presentation outlines a study on pharmaceutical chemical contamination in surface water. Topics covered include: estrogen hormones; adverse ecological effects; effect of effluents from wastewater treatment plants; sources of estrogen; compounds of interest; analytical methods; free estrogen methods; percentage recovery and RSD ofSPE – GC/MS Analysis; detection limits (ng L<sup>-1</sup>); Presence of Emerging Contaminantsin Surface Waters; stream sampling; and, PNEC Values of Hormones andObserved Concentration Range. The second part of this study examined the aqueous phase destruction of pharmaceutical chemical contamination using ultrasound. Topics covered in this section include: Schematic and Picture of SonicationUnit; experimental system conditions; batch system equations; rate constant vs. pH; peroxide effects – degradation percentwith time; hydrogen peroxide effects -dosage and pH; effect of alkalinity; process conditions; continuous flow reactor – mass balance; correlation between molecular weightand first order degradation rates; Predicted vs. Observed Degradation; and, future/on-going work. Includes 4 references, figures.
