Development of an accurate and sensitive analytical method for the determination of cadmium at trace levels using dispersive liquid-liquid microextraction based on the solidification of floating organic drops combined with slotted quartz tube flame atomic absorption spectrometry was written by Aydin, Ilgin;Chormey, Dotse Selali;Budak, Tuerkan;Firat, Merve;Turak, Fatma;Bakirdere, Sezgin. And the article was included in Journal of AOAC International in 2018.Synthetic Route of C18H37Cl This article mentions the following:
A dispersive liquid-liquidmicroextraction(DLLME) technique based on a solidification-of-floating-organic-drop (SFOD) procedure was developed for the determinationof trace amountsof cadmium (Cd) by using a flame at.absorption spectrometer (FAAS) fitted with a slotted quartz tube (SQT). The extractionof Cd was achieved by forming a complex with diphenylcarbazone. Parameters affecting the formation of complex and extractionoutputs were carefully optimized to obtain high-absorbance signals to achieve lower LODs. An SQT was fitted on top of the flame burner head to further enhance the absorbance of the signals recorded by the FAAS. Coupling the DLLME-SFOD procedure with SQT-FAAS produced an enhancement factor of about 183. The LOD of the method was 0.23μg/L with an RSD of 3.8%. Matrix-matching was used to overcome any low recovery results obtained with tap water and municipal wastewater. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Synthetic Route of C18H37Cl).
1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Synthetic Route of C18H37Cl
