Developing A Novel Method for The Determination of Silver In Real Samples Using Slotted Quartz Tube Atomic Absorption Spectrometry (Sqt-Aas)
Silver is a valuable metal with antibacterial properties. The industry has a widespread use; It is mostly used in water purification and medicinal products. For this reason, the quantity of silver is important for industrial applications. Flame Atomic Absorption Spectrometer (FAAS) is a widely used technique for the determination of elements. However, due to the low sensitivity and the relatively short duration of the analyte atoms remaining in the measurement zone, FAAS is inadequate for some situations to determine elements. To overcome this sensitivity problem, some atom traps have been developed in recent years. In this study; in order to increase sensitivity of FAAS technique, a slotted quartz tube (SQT) have been used. SQT is a sensitive, easy and economical way to determine silver in any real samples. The aim of this study is to develop a sensitive, easy and economical technique with the help of SQT for silver determination. In addition, using this sensitive technique, the determination of the silver concentration in soil and clay samples taken from Burdur region has been performed. LOD values for silver determination were obtained as 0.07 mg/L and 0.03 mg/L for AAS and SQT-AAS techniques, respectively. Using SQT device, sensitivity of the system was increased about 2.33 times for Ag determination.
