摘　　要：本文比较了火焰原子吸收光谱法(FAAS)和硫氰酸盐分光光度法在测定水中铁含量方面的性能。FAAS以其高敏感度和精确度著称,适用于追踪水中微量铁含量,尽管它的设备成本和操作复杂性较高。相比之下,硫氰酸盐分光光度法操作简便,成本较低,适用于常规水质检测和现场快速检测,但在敏感度和精确度方面略逊于FAAS。选择哪种方法取决于具体的测试需求、可用资源和所需的精确度。总的来说,对于高精确度的实验室分析和专业应用,FAAS是更佳选择;而硫氰酸盐分光光度法则适合于预算有限和快速现场检测的情况。The properties of flame atomic absorption spectrometry(FAAS) and thiocyanate spectrophotometry for determination of iron in water were compared in this paper.Known for its high sensitivity and accuracy,FAAS is suitable for tracking trace amounts of iron in water,despite its high equipment cost and operational complexity.In contrast,thiocyanate photometry is easy to operate,low cost,suitable for routine water quality detection and field rapid detection,but in terms of sensitivity and accuracy slightly inferior to FAAS.Which method you choose depends on the specific test requirements,available resources,and the required precision.In general,FAAS is the preferred choice for high-precision laboratory analysis and professional applications;The thiocyanate photometric method is suitable for the situation of limited budget and fast field detection.
