A sensitive and robust trap method was developed for the determination of cadmium (Cd) by using a slotted quartz tube. Using this method at a sample suction rate of 7.4 mL/min for 4.0 min collection, a 1467-fold increase in sensitivity was obtained compared to the flame atomic absorption spectrometry method. Under the optimized conditions, a limit of detection of 0.075 ng mL was obtained for the trap method. The interference effects of hydride-forming elements, transition metals, and some anions on the Cd signal were investigated. The developed method was evaluated by analyzing "Sewage Sludge-industrial origin (BCR no: 146R)", "NIST SRM 1640a Trace elements in natural water", and "DOLT: 5 Dogfish Liver". There was a good agreement between the certified and found values at the 95% confidence level. This method was applied successfully for the determination of Cd in drinking water and some fish tissue samples (liver, muscle, and gill) obtained from Muğla province.
开发了一种灵敏且稳健的捕集方法，用于使用开槽石英管测定镉（Cd）。使用该方法，在7.4 mL/min的样品抽吸速率下收集4.0分钟，与火焰原子吸收光谱法相比，灵敏度提高了1467倍。在优化条件下，捕集法的检出限为0.075 ng/mL。研究了氢化物形成元素、过渡金属和一些阴离子对Cd信号的干扰效应。通过分析“工业来源污水污泥（BCR编号：146R）”、“NIST SRM 1640a天然水中的微量元素”和“DOLT：5角鲨鱼肝”对所开发的方法进行了评估。在95%置信水平下，认证值和测定值之间具有良好的一致性。该方法成功应用于测定来自穆拉省的饮用水和一些鱼类组织样品（肝脏、肌肉和鳃）中的Cd。
