Özet
A new magnetic dispersive micro-solid phase extraction (d-& micro;SPE) procedure and inductively coupled plasma mass spectrometer (ICP-MS) are combined for the separation and determination of inorganic (iron, copper, arsenic, mercury), biological (microbial), and organic pollutants from wastewater samples. To this end, a novel magnetic nanocomposite (LiNiFe2O4-MCM-41, LNFM) was synthesized/characterized, and the LNFM@PVDF nanofiber membranes were obtained via electrospinning. The optimal conditions were found to be: pH 4.0; 1-mL of 2.0 mol L-1 HNO3 as the eluent reagent and sample volume: 250-mL except for As (As: 25-mL). For adsorption studies, the LNFM @PVDF nanofiber membrane reached equilibrium very fast (in only 3 min) upon vortexing. The limits of detection (LOD) and preconcentration factors (PF) of the d-& micro;SPE method were determined as follows: 0.01 & micro;g L-1 and 250 for Fe, 0.04 & micro;g L-1 and 250 for Cu, 0.02 & micro;g L-1 and 25 for As, and 0.04 & micro;g L-1 and 250 for Hg, respectively. The precision of the d-& micro;SPE method was found to be <= 1.6%. The d-& micro;SPE procedure was validated by certificate reference material (CWW-TMD wastewater) analyses and recovery tests in wastewaters, lake water, sea water, sea mucilage, rain water, and tap water samples yielding recoveries in the range of 96%- 101%. Therefore, LNFM@PVDF nanofiber membrane can be used as a suitable adsorbent for the d-& micro;SPE of iron, copper, arsenic, mercury, biological and organic pollutants from wastewater.
