Elemental Analysis of Hypericum triquetrifolium Species by Inductively Coupled Plasma Mass Spectrometry

Öz

The aim of this study is to explore the presence and content of metals; lead(Pb), Mercury(Hg), arsenic(As), selenium(Se) and semi-metals; aluminium (Al), cadmium (Cd), copper (Cu), iron (Fe), nickel (Ni), zinc (Zn), Cobalt (Co), calcium (Ca), potassium(K) in aerial part of Hypericum triquetrifolium species collected from Adana-Tarsus by using inductively coupled plasma-mass spectrometry (ICP-MS) method. A convenient microwave technique has been used at the stage of preparing the plant sample for analysis. As a result of ICP-MS measurements, heavy metals with high toxicity such as mercury (0.35±0.01mg.kg-1) and lead (6.36±0.25mg.kg-1), were determined, however other heavy metal such as arsenic and cadmium were not found in the plant sample. The results obtained showed that the alkaline earth metals, calcium (1226.780 ± 43.4 mg.kg-1) and potassium (10308 ± 103.7 mg.kg-1) contents were found to be quite high in the plant sample. The amounts of other elements analyzed in the plant species were; Se (129.8± 3.9 mg.kg-1) Al (373.95±17.1 mg.kg-1), Cu (12.6±0.7 mg.kg-1), Fe (609.3±24.1 mg.kg-1), Ni(8.7±0.4 mg.kg-1), Zn(25.2±1.2 mg.kg-1), Co (0.08±0.01mg.kg-1),respectively.

İndüktif Eşleşmiş Plazma-Kütle Spektrometresi ile Hypericum triquetrifolium Türünün Elementel Analizi

Öz

Bu çalışmada Adana-Tarsus bölgesinden toplanan Hypericum triquetrifolium bitkisinin topraküstü kısımındaki metaller; kurşun(Pb), civa(Hg), arsenik(As), selenyum(Se) ve yarı metaller; alüminyum (Al), kadmiyum (Cd) bakır (Cu), demir (Fe), nikel (Ni), çinko (Zn), kobalt (Co), kalsiyum (Ca), potasyum(K) içerikleri indüktif eşleşmiş plazma-kütle spektrometresi (ICP-MS) yöntemi ile incelenmiştir. Bitki numunesinin analize hazır hale getirilmesi aşamasında mikrodalga yakma yöntemi ile numuneler çözünür hale getirilmiştir. ICP-MS ölçümleri sonucunda, yüksek toksik özellik gösteren kadmiyum ve arsenik metallerine rastlanmazken, diğer yüksek toksik özellik gösteren ağır metal içerikleri; civa (0,35±0,01mg.kg-1) ve kurşun (6,36±0,25mg.kg-1) olarak belirlenmiştir. Elde edilen sonuçlar, bitki numunesinde toprak alkali metallerden kalsiyum (1226,780±43,4 mg.kg-1) ve potasyum (10308±103,7 mg.kg-1) içeriklerinin oldukça yüksek oranda bulundukları tespit edilmiştir. Bitki içeriğinde analizi gerçekleştirilen diğer elementlerin miktarları; Se (129,8± 3,9mg.kg-1) Al (373,95±17,1 mg.kg-1), Cu (12,6±0.7 mg.kg-1), Fe (609,3±24,1 mg.kg-1), Ni(8,7±0,4 mg.kg-1), Zn(25,2±1,2 mg.kg-1), Co (0,08±0,01 mg.kg-1) olarak belirlenmiştir.
