提出了一种基于杂原子大环荧光团(二氮杂冠醚、金属配位体和吡啶膦)的新型全固态光学传感器阵列，用于液体介质的照相分析。在单选择传感器模式和多传感器排列的情况下，评价了新光学系统对多种不同物种(阳离子：Li+、K+、Na+、Mg~(2+)、Ca~(2+)、Co~(2+)、Cu~(2+)、锌~(2+)、Cd~(2+)、Pb~(2+)和阴离子：、Cl-−、Br-−)的灵敏度。在所有测试浓度范围内，Cd~(2+)、Cu~(2+)、Zn~(2+)和离子的传感器阵列光学响应与被分析物浓度之间建立了满意的最小二乘回归模型。在这些物种中，镉和亚硝酸盐离子的检测受到了最高的关注，用3σ方法估算的检出限DL分别为0.0013 mg/L和0.21 mg/L，低于世界卫生组织指导值0.003 mg/L(镉)和2 mg/L()。所开发的传感器适用于常见的信号采集设备(发光二极管，LED作为光源，数码相机作为信号检测器)，以及用于数据处理的化学计量学方法，以在具有环境重要性的真实样品中对感兴趣的物种进行快速和低成本的监测。
The development of a novel all-solid-state optical sensor array based on heteroatomic macrocyclic fluorophores (diaza-crown ether, metallocorrole and pyridinophans) for the photographic analysis of liquid media, is presented. The sensitivity of the new optical system toward a number of different species (cations: Li+, K+, Na+, , Mg2+, Ca2+, Co2+, Cu2+, Zn2+, Cd2+, Pb2+ and anions: , , Cl−, Br−, ) was evaluated both in single selective sensor mode and in multisensory arrangement. The satisfactory PLS1 regression models between sensor array optical response and analyte concentration were obtained for Cd2+, Cu2+, Zn2+, and ions in all the range of tested concentrations. Among these species the highest attention was focused onto detection of cadmium and nitrite ions, for which the detection limits, DL, estimated by 3σ method were found 0.0013 mg/L and 0.21 mg/L respectively, and these values are lower than the corresponding WHO guideline values of 0.003 mg/L (Cd2+) and 2 mg/L (). The suitability of the developed sensors implemented with familiar devices for signal acquisition (Light Emitting Diode, LED, as light source and a digital camera as a signal detector), and chemometric methods for data treatment to perform fast and low-cost monitoring of species under interest, in real samples of environmental importance, is demonstrated.
