摘要

罗丹明 B、水合肼和盐酸生成中间体 LBXJ。接着，LBXJ、3-甲醛铬酮和 100 % 乙醇制备出探针 Y2ST。核磁共振、红外和质谱对中间体和探针的结构进行了描述。确定结构后，对样品的响应时间、pH 值、线性度、检测限、准确度、配位比和回收率进行了测试。此外，还比较了离子的荧光选择性。在 5 × 10-6 mol/L--5 × 10-5 mol/L 的条件下，葡萄糖酸锌中 Zn2+ 的检测率为 96.1%，而 Y2ST 的检测限为 0.7 × 10-6 mol/L。该方法可用于 Zn2+ 含量的测定。

Study on the Properties of rhodamine B fluorescent probe Y2ST

Rhodamine B, hydrazine hydrate, and HCl generated the intermediate LBXJ. Next, LBXJ, chromone 3-formaldehyde, and 100 % ethanol prepared the probe Y2ST. NMR, IR, and MS. described the intermediate and probe structures. Following the determination of the structure, tests were conducted on the response time, pH value, linearity, detection limit, accuracy, coordination ratio, and recovery of samples. Additionally, the fluorescence selectivity of ions was compared. The rate of Zn²⁺ detection in zinc gluconate was 96.1 % at 5 × 10⁻⁶ mol/L--5 × 10⁻⁵ mol/L, while the detection limit of Y2ST was 0.7 × 10⁻⁶ mol/L. It can be applied to Zn²⁺ content determination.
