A fluorescent chemosensor with high sensitivity and selectivity for palladium species based on a conjugate of phosphine and rhodamine B has been developed. The chemosensor showed an excellent palladium selectivity with a detection limit down to the 10â9 M range, which is lower than the WHO limit for palladium content in drug chemicals.
基于膦和罗丹明 B 的共轭物,一种对钯具有高灵敏度和高选择性的荧光化学传感器被开发出来。该化学传感器具有极佳的钯选择性,检测限低至 10â9 M 范围,低于世界卫生组织对药物化学品中钯含量的限制。
