【摘要】 <正>本文基于罗丹明B的衍生物RND设计了一种新型的PVC膜传感器,可用于汞离子的选择性识别。该传感器对汞离子具有荧光增强的特异性响应,线性响应范围为1.0×109到2.0×103M,检出限低至8.1×1010M。更多还原

【Abstract】 A novel prepared mercuric ion PVC membrane sensor based on a Rhodamine B derivative(RND) as a selective sensing material was described.The sensor has also been incorporated into a flow-cell for determination of Hg2+ in flowing streams with improved sensitivity and detection limit.The proposed fluorescence optode was successfully applied to detect Hg2+ in environmental water samples and fish.更多还原
