【摘要】 研究以下沿1,3-位用水杨醛酰腙基团修饰的杯[4]芳烃衍生物L作为Zn²⁺荧光探针的性能。L浓度为1.0×10^-4mol·L^-1时,Zn²⁺浓度在4.0×10^-6mol·L^-1～4.0×10^-5mol·L^-1范围内体系的荧光强度与Zn²⁺浓度呈良好的线性关系,相关系数0.999,检出限1.0×10^-6mol·L^-1。金属离子Na⁺、Mg²⁺、Ni²⁺、Cd²⁺、Mn²⁺、Pb²⁺和Cu²⁺优先选择性实验结果表明,Na⁺、Mg²⁺、Cd²⁺和Pb²⁺的存在不影响体系的荧光强度,但Ni²⁺、Mn²⁺和Cu²⁺将干扰L对Zn²⁺的测定。更多还原

【Abstract】 The properties of fluorescent probe L for Zn²⁺ ion,which is a calix[4]arene derivative modified by salicylaldehyde acylhydrazone at 1,3-low rim,was investigated.At the concentration 1.0×10^-4 mol·L^-1 for ligand L,when the concentration of Zn²⁺ ion was in the range of 4.0×10^-6 mol·L^-1～4.0×10^-5 mol·L^-1, there was a good linearity between the fluorescence intensity of the system and the concentration of Zn²⁺ ion with a correlation coefficient of 0.999,and the detection limit was 1.0×10^-6mol·L^-1.Result about the priority selectivity test of the probe to metal ions including Na⁺,Mg²⁺,Ni²⁺,Cd²⁺,Mn²⁺,Pb²⁺ and Cu²⁺ showed that the fluorescence intensity of the system had not been influenced by the existence of Na⁺,Mg²⁺, Cd²⁺ and Pb²⁺ ion,but by Ni²⁺,Mn²⁺ and Cu²⁺ ion,which meant they could interfere with the determination of Zn²⁺ ion.更多还原
