Aas Determination of Some Trace Heavy Metals in Lake Van Water After Preconcentration by Complexation With Surface Functional Groups on Activated Carbon
(Parlar Scientific Publications (p S P), 2005) Kiliçel, F; Gökalp, F
The adsorption of some trace heavy metals on a granulated, pure and activated carbon (Riedel-de Haen, 18002) was characterized assuming that it takes place by formation of complexes with functional groups, present in the activated carbon. The concentrations were determined for each element in aqueous suspension at constant acidity. An atomic absorption spectrometric method for the determination of the trace heavy metals (Zn, Pb, Cd, Cr, Ni, Cu, Co, Bi, Mn) in Lake Van water and that of the rivers flowing into the lake has been developed after adsorption of their diethyldithiocarbamate (DEDTC) complexes on activated carbon. Complexes were adsorbed on the adsorbent at pH 3.2 +/- 0.1. Trace heavy metal ions were elueted with 20 ml of 1 M HNO3 and determined by flame atomic absorption spectrometry (FAAS). Under optimum conditions, the trace heavy metal ions in aqueous samples were concentrated about 50-fold by column treatment and recovery rates of the investigated metals were in the range 79-106%.
Determination of Some Heavy Metal Levels in Muscle Tissues of Lake Van Fish (Chalcalburnus Tarichi)
(Asian Journal of Chemistry, 2005) Kiliçel, F; Gökalp, F
Some heavy metal (Zn, Pb, Cd, Cr, Ni, Co, Bi, Mn, Cu) concentrations in the muscle tissues of Lake Van fish (Chalcalburnus tarichi) were measured and compared with sea fish. Metal concentration in muscles was investigated by linear regression analysis. Concentration (as mu g/g dry weight) was highest for Zn (1.806 +/- 0.553) and lowest for Cd (0.032 +/- 0.014). Cu was not measured. The highest concentration of Zn (3.02), Pb (0,09), Cd (0.06), Cr (0.09), Ni (0.44), Co (0.26), Bi (0.64) and Mn (0.42) were measured in muscle tissues of Lake Van fish (Chalcalburnus tarichi).
Heavy Metal Contamination in Soils of Garbage Area in Van, Turkey
(Asian Journal of Chemistry, 2006) Kiliçel, F
In this study, some heavy metal concentrations in soils of the garbage area in Van, Turkey, by flame atomic absorption spectrometry (FAAS) have been determined. Ni, Co, Cr, Cd and Ca concentrations are the highest; Zn, Cu, Mn and Fe concentrations are higher than control sample concentrations. Metal concentrations in the spring season are higher than in the autumn season except Cd. Wastewater of this garbage area enters into the soil and Puddle Sihke where the water of Puddle Sihke is used as irrigation water and arrives at Lake Van.
