Determination and comparison of metal contents in simulated body fluid medium conditions of the plant species by flame atomic absorption spectrometry (FAAS)

Bu çalışmada, gıda ve tıbbiamaçlar için kullanılan bazı bitki türlerinin (Arum conophalloides,Arum detruncatum, Ornithogalum narbonense Muscari comosumve Lippia citrodora) multi-element içerikleri indüktif eşleşmiş plazmalı kütle spektrometresi (ICP-MS) ile tayin edilmiştir. Çalışmada kullanılan türler önce mikrodalga çözünürleştirme işleminde derişik nitrik asit ve hidrojen peroksit ilave edilerek yakma işlemi yapılmıştır. Daha sonra elde edilen çözelti son hacim 100 mL olacak şekilde seyreltilmiş ve ICP-MS ile analiz edilmiştir. Aynı cinsin farklı türlerinin element içerikleri birbiriyle karşılaştırılmıştır. Bu cinslere ait türlerin element içerikleri birbirinden farklı olduğu ve bu farlılık ise bitkinin genetik yapısı, coğrafi konum, iklim ve çevre koşullarına bağlı olduğu belirlenmiştir. Ayrıca, bu çalışmada metot validasyon çalışması yapılmıştır.

“…For this reason, analytical methods to determine the amount of lead in the environment are very important. There are known procedures for determining lead by flame atomic absorption spectrometry (FAAS) or inductively coupled plasma mass spectrometry (ICP-MS), but these are not methods that can be easily or cheaply used under field conditions [3][4][5][6][7]. Electrochemical methods, such as stripping voltammetry, are far better for such applications [8].…”

A copper film-modified, carboxyl-functionalized, and multi-walled carbon nanotube (MWCNT-COOH)-modified screen-printed carbon electrode (CuF/MWCNTs/SPCE) was used for lead determination using anodic stripping voltammetry. The main parameters were investigated and optimized during the development of the research procedure. The most optimal electrolyte concentrations were determined to be 0.4 M HCl and 6.3 × 10−5 M Cu(II). The optimal parameters for voltammetric stripping measurements are as follows: an accumulation potential of −0.7 V; an accumulation time of 120 s; and a pulse amplitude and pulse time of 120 mV and 2 ms, respectively. The effect of surface active substances and humic substances as potential interferents present in aqueous environmental samples was investigated. The validation of the procedure was carried out using certified reference materials, like waste water SPS-WW1 and environmental matrix TM-25.5. In addition, the developed procedure was applied to investigate lead recovery from natural environmental water, such as rivers and lakes.
