建立了一种基于锌试剂与氰化物竞争结合的金属络合指示剂置换法（M-IDA）测定氰化物浓度。在某些真实的样品中，CN-的浓度可在pH = 9.0时通过测定484 nm处的吸光度来测定。该系统显示了XNOR逻辑功能，使用Zn（II）和氰化物作为化学输入，并且Zincon的颜色强度（在484 nm处）作为输出。在15 s以下的快速响应中，检出限为1.92 × 10 ~（-7）mol L ~（-1）（0.005 ppm），其它阴离子物质不干扰。采用PC-ANN算法提高了系统的工作范围。采用氰化物检测法测定生物样品中的氰化物。(C)2014爱思唯尔有限公司版权所有。
A metal complexing indicator displacement assay (M-IDA) based on competition between Zincon and Cyanide for binding with Zn (II) was developed to determine cyanide concentration. The concentration of CN- can be determined at pH = 9.0 in some real sample by measuring the absorbance at 484 nm. This system showed a XNOR logic function using Zn (II) and cyanide as chemical inputs and the color intensity of Zincon (at 484 nm) as output. cyanide can be detected with a detection limit of 1.92 x 10(-7) mol L-1 (0.005 ppm) in a fast response below 15 s and no interference of other anionic materials. The working range was improved by using PC-ANN algorithm. Cyanide detection method was applied to determine cyanide anion in biological samples. (C) 2014 Elsevier B.V. All rights reserved.
