syntheses of organochalcogen-supported azacalix[3]arenes and their behavior toward metal ions sensing was investigated by spectrochemical (UV-vis, 1 H NMR and 77 Se NMR) methods. The azacalix[3]arenes prepared have shown better potentiometric response for uranyl ions compared to alkali (Na+, K+), alkaline-earth (Mg 2 + , Ca 2 + , Ba 2 + ), transition and heavy metal (Co 2 + , Ni 2 + , Cu 2 + , Ag+, Zn
通过光谱化学(UV-vis、 1 H NMR 和 77 Se NMR)方法研究了有机硫元素负载的氮杂杯[3]芳烃的一锅合成及其对金属离子传感的行为。与碱(Na+、K+)、碱土(Mg 2 + 、Ca 2 + 、Ba 2 + )、过渡金属和重金属(Co 2 + 、 Ni 2 + , Cu 2 + , Ag+ , Zn 2 + , Cd 2 + , Pb 2 + , Fe 3 + ) 离子,因此可以作为有效的离子载体用于制备基于 PVC 膜的离子选择性电极,用于测定铀酰离子。
